Abstract
Problems concerning the production of diesel fuel and motor petrol at small-scale installations intended for oil and gas condensate processing into motor fuel are considered. It is shown that for a large number of oil and gas condensate deposits the virgin diesel fractions correspond in their physicochemical characteristics to the requirements of standards for diesel fuel. In some cases, graded diesel fuel can be obtained by varying the fraction composition and/or using the corresponding additives. For the production of graded automobile petrol at small-scale installations, the most optimal process is Zeoforming, which is based on the use of a zeolite-containing catalyst. It is shown that varying the process conditions one may manufacture petrol of required grades (from AI-80 to AI-96, of summer and winter kinds) from low-octane hydrocarbon fractions of different origin without preliminary desulphurization or hydrofining and without any use of hydrogen-containing gas. In comparison with reforming, petrol obtained by Zeoforming Process is characterized by lower content of aromatic hydrocarbons, especially benzene.
