Annotation:

The authors of the article focus on the study of gas condensate effect in the water-methanol waste of natural gas on the conversion methanol on modified silica gel adsorbents ASM. The effect of gas condensate on the catalytic activity of industrial adsorbents was studied at an experimental installation of a cyclic process and a unit of gas preparation for transportation. According to the data of elemental analysis, phase analysis, parametric characteristics (specific surface area and specific pore volume) of samples and the catalytic activity of adsorbents, the conversion of methanol in the water-methanol waste of natural gas in the presence of gas condensate was estimated. The decrease of methanol conversion to dimethyl ether in the presence of gas condensate was revealed due to the presence of hydrocarbons in the gas condensate, capable of forming coke deposits at the stage of high-temperature regeneration and a change of the specific surface area of adsorbents with a constant phase composition and concentration of aluminum oxide.
