A combined promoting effect of lanthanum and molybdenum on the catalytic properties of highsilica zeolite in natural gas conversion into liquid hydocarbons has been studied. It has been shown that lanthanum additives to the Mo-containing zeolite lead to an increase in the activity and selectivity of a catalyst in the formation of aromatic hydrocarbons from the components of natural gas. It has been found that the maximum amount of aromatic hydrocarbons are formed in the presence of a zeolite containing 1.0% La and 4.0% Mo. Using thermal desorption of ammonia, data has been obtained on the amount and strength of acid sites in modified zeolites.
