  • Conversions of low molecular weight hydrocarbons to higher molecular weight hydrocarbons using a silicon compound-containing catalyst
    Patent number: 4567311
    Abstract: Disclosed is a catalytic process for the production of higher molecular weight hydrocarbons from lower molecular weight hydrocarbons. More particularly, disclosed is a catalytic process for the conversion of methane to C.sub.2 + hydrocarbons, particularly hydrocarbons rich in ethylene or benzene, or both. The process utilizes a silicon compound-containing catalyst, high reaction temperatures of greater than 1000.degree. C., and a high gas hourly space velocity of greater than 3600 hr.sup.-1.
