Reforming types

There are two major types of reforming: thermal and catalytic. Thermal reforming is a conversion of appropriate fractions of primary oil distillation into high-octane gasolines induced by high temperatures only. In more advanced catalytic reforming, conversion of original raw material takes place with simultaneous application of process catalysts and high temperatures. While the catalytic reforming is a more effective option, thermal reforming remains in use due to its lower cost; however, in developed countries, it has been almost completely expelled from petrochemical industry.

In the course of the catalytic reforming process, the catalyst gradually loses its activity and needs regeneration or replacement. Therefore, three options are considered for the chemical process arrangement:

1) regeneration from time to time;

2) cyclic regeneration;

3) continuous regeneration.

For the first option, reforming takes place in continuous mode over the stationary layer of catalyst; no regeneration is provided for this layer, and it must be replaced from time to time. For the second option, the stationary layer of catalyst is also used; however, unlike the first option, the layer is regenerated. If several reactors are used, regeneration can be carried out both simultaneously in all devices (the process has to be suspended for this purpose) and alternately, when a device is taken out from the process, one by one, for catalyst replacement, while the reforming process itself is not stopped. If the third option is used, a reactor is provided with a supplementary regeneration unit; in this configuration, the catalyst is being continuously circulated between the reactor and the regeneration unit; and, as a result, catalyst regeneration is possible while the production is not stopped.

The service life of a platinum catalyst is significantly reduced by impurities that can be found in the raw material, such as as nitrogen, sulfur, lead and other substances that are catalytic poisons. Molecules of catalytic poisons interact with active centers of catalysts, significantly reducing their effectiveness or resulting in catalyst poisoning (deactivation). If such substances are found in a raw material for reforming, this material, before being placed into the reactor, must be pre-treated by hydrofining with hydrogen. This process is arranged as follows: straight-run gasolines are passed through a gas containing hydrogen. During this process, harmful impurities are bounded; as a result, their concentration in raw material is reduced to an admissible level.

To extract aromatic hydrocarbons from liquid reforming products, various non-standard methods are used because the boiling temperature of naphthenic and paraffinic hydrocarbons is close to the boiling temperature of aromatic hydrocarbons. To extract toluene, benzene and mixture of xylenes, liquid extraction with sulfolanes and polyethylene glycols is used. Such individual hydrocarbons as С8 and С9 are extracted by crystallization, adsorption and (in some cases) superfractionating.

Reforming catalysts

For reforming, bifunctional catalysts are used in the form of porous promoted aluminum oxide, with platinum alloys or small-size platinum crystals applied on it. Oxide and metal areas in catalysts serve as active centers. Such reactions as hydrogenolysis, hydrogenation, dehydrogenation and, partially, dehydrocyclization take place on a metal component. An oxide component is a catalyst for such reactions as hydrocracking, isomerization and, partially, dehydrocyclization. At enterprises in Russia, catalysts in the form of aluminum oxide promoted by chlorine or fluorine are used for reforming. Also, when a catalyst is made, platinum (sometimes in combination with metal promotor) is uniformly distributed on it. To suppress hydrogenolysis reactions, catalysts are sulfurated.

Operating characteristics of catalysts considered as the most important are selectivity, activity and stability. So, for reforming, catalyst must provide maximum output of hydrogen and liquid products (maximum selectivity). At the same time, hydrocarbon aromatization reactions must be as deep as possible, while the catalyst activity in hydrogenolysis and hydrocracking must be minimal. Otherwise, content of gaseous hydrocarbons in a raw material will grow and the end product output will decrease.

Under certain conditions, octane rating of a product (from conversion of an original raw material) or the product’s content of aromatic hydrocarbons can be considered as the reforming effectiveness indices.

Catalyst stability means its capability to keep its initial selectivity and activity within a period of time. In other words, the reforming catalyst must have sufficient aggregate service life and sufficient cycle length between regenerations. One more important characteristic of a catalyst’s stability is high wear resistance, especially against abrasion and crushing. If there is no sufficient mechanical strength, dust and debris will be accumulated in pipelines and a device of the reforming plant, resulting in growth of pressure difference and hindered flow of gaseous mixtures in the system.

Deactivation (poisoning) of platinum catalyst can also be caused by such factors as reduction of catalyst dispersity, coke deposits and accumulation of catalytic poisons that cannot be removed. The former causes can be eliminated by application of oxidizing regeneration followed by platinum treatment using organochlorine compounds in oxidizing environment at high temperatures. As for catalytic poisons, these are the compounds of lead, copper and arsenic that react with platinum and, as a result, the catalyst’s functions of hydrogenation and dehydrogenation are impaired. If a catalyst is poisoned by metals, it quickly cokes up, and it does not restore its activity after regeneration. Hence, the permissible content of aforementioned compounds in an original product is 0.3 mg/kg but not higher, while content of sulfur and nitrogen compounds may be 10-20 mg/kg and up to 1 mg/kg respectively.

Principal reforming reactions

Production of high-octane gasolines by catalytic reforming is possible in several reactions increasing the octane rating. These reactions include:

  1. formation of benzene-like aromatic molecules from heavy paraffinic hydrocarbons due to fiber peeling;
  2. conversion of linear paraffinic hydrocarbons into branched isomers;
  3. dehydrogenation of cyclic saturated hydrocarbons (naphthenes) followed by their conversion into aromatic molecules;
  4. hydrocracking of paraffinic hydrocarbons into light fractions with high octane rating.

Reactions that take place on reforming catalysts fundamentally change the hydrocarbon composition of gasoline fractions. In this process, aromatization of hydrocarbons under treatment has the highest priority. The final stage of aromatic hydrocarbons’ formation takes place during the alkylcyclohexanes dehydrogenation phase. Dehydrocyclization of heavy paraffinic hydrocarbons has an intermediate stage of formation of alkylcyclohexanes (followed by dehydrogenation) and alkylcyclopentanes. Paraffinic hydrocarbons are isomerized by reforming catalysts during the intermediate stage of formation of carbonium ions and slightly-branched isomers. Isomerization of alkylcyclopentanes into alkylcyclohexanes is also among the principal reforming reactions.

In certain cases, reforming is carried out with hydrogenolysis of heavy paraffinic hydrocarbons; due to this reaction, gaseous hydrocarbons, such as methane, can be produced. This reaction takes place on metal areas of catalyst used in reforming. Paraffinic and naphthenic hydrocarbons pass through the hydrocracking; this reaction takes place on acidic areas of catalyst. However, initial and final stages of hydrocracking, when olefins are produced and decomposition products are hydrogenated, take place on metal areas of catalyst. This is caused by their hydrogenating and dehydrogenating functions.

Moreover, under the conditions of catalytic reforming, there are several reactions that hardly affect the final formation of major products of the process though they have a significant impact on stability and activity of catalysts. They include the reaction of decomposition of chlorine-containing, nitrogenous and sulfurous compounds as well as reactions resulting in coke formation on the catalyst. The background for the coke formation process is the catalyst coking, the surface compaction reaction reducing the activity and worsening the selectivity.

Moreover, coking is affected by such factors as catalyst poisoning by catalytic poisons, reduction of hydrogen versus original raw material molar ratio, drop of partial pressure, imbalance of acidic and hydrogenating functions of catalyst and conversion of raw materials with high content of heavy and light hydrocarbons. It is assumed that the quickest reforming reaction is the reaction of dehydrogenation of cyclohexane and its chemical compounds into aromatic hydrocarbons. The reaction of dehydrocyclization of paraffinic hydrocarbons is the slowest. Dehydrocyclization as well as hydrocracking can be accelerated by maximum possible temperature rise.

Sulfurous compounds, depending on their structure, are converted during the reforming into aromatic, naphthenic or paraffinic hydrocarbons absorbing hydrogen and releasing hydrogen sulfide. Nitrogen-containing compounds on a catalyst are converted into similar hydrocarbons; however, ammonia is released during this process. Reforming reactions during which aromatic hydrocarbons are produced from naphthenes and paraffins absorb heat. Hydrogenolysis and hydrocracking reactions are essentially exothermic, while isomerization of naphthenic and paraffinic hydrocarbons has almost zero thermal effect.
