Conversion of propane-butane fraction to arenes on zeolite catalystsmodified by gallium oxides

Abstract

The main industrial technologies used currently for the conversion of natural and associated petroleum gas (APG) aresteam reforming of methane and APG into synthesis gas on alum-nickel catalysts which is carried out at 860–950 ° Cand the Fisher-Tropsch process. The synthesis gas is further processed into hydrocarbons on iron and cobalt catalysts.The high temperature (860–950 ° C) in the processes, especially at the first stage of synthesis gas production and the lowselectivity of the target products in the Fischer-Tropsch process are major drawbacks of these technologies for theprocessing of natural gas (methane) and APG. The paper provides the comparative analysis of the activity and selectivityof microporous high-silica zeolites of the ZSM-5 type, synthesized using various additives, during the conversion ofnatural associated gas.
