METHOD FOR CATALYTIC PROCESSING OF METHANE

摘要

The invention relates to the production of hydrocarbons, in particular to the production of hydrocarbons having molecular mass which is higher than the molecular mass of methane. Said invention can be used for producing high quality hydrocarbon products such as components of motor fuels and C3-C5 aliphatic hydrocarbons. The processing of methane for producing hydrocarbons having a carbon atomic number higher than one (c2<+>) is carried out by adding to methane a hydrocarbon material, having an atomic number higher than one, in a quantity equal or higher than 5 % of a total quantity of the hydrocarbon material supplied to a system of reactors. The process is carried out using a catalyst containing, mass %: Acid component equal or higher than 3.0 Hydrogenating component equal or higher than 0.1 The rest being a carrier Amorphous aluminium silicate, synthetic silicium aluminium phosphate (SAPO) or ceolite is used as the acid component. A group VIII metal alloys of groups VIII and VIA metals, groups II-IV metal oxide(s) or VI and VII groups metals sulphides can be used as the hydrogenating component. As a carrying agent, the catalyst contains aluminium oxide, aluminium silicate clay or the mixture thereof and a mesoporous material. Unsaturated hydrocarbons C2-C4 or large ranges of hydrocarbon fractions steaming away up to a temperature of 560 DEG C are added into methane as a C2<+> component.
