Abstract
In a process for converting methane to aromatic hydrocarbons, a feed containing methane is supplied to one or more reaction zone(s) containing catalytic material operating under reaction conditions effective to convert at least a portion of the methane to aromatic hydrocarbons; the reaction zone(s) being operated with an inverse temperature profile.
Claims23
A process for converting methane to higher hydrocarbon(s) including aromatic hydrocarbon(s) in a reaction zone, the process comprising:
- (a) providing to said reaction zone a hydrocarbon feedstock containing methane;
- (b) providing a quantity of catalytic material within said reaction zone;
- (c) maintaining the said reaction zone with an inverse temperature profile;
- and
- (d) operating said reaction zone under reaction conditions sufficient to convert at least a portion of said methane to a first effluent having said higher hydrocarbon(s) wherein sufficient quantity of catalytic material is provided so that the percentage approach thermodynamic equilibrium conversion of methane to benzene at the reaction zone halfway point (in terms of quantity of catalytic material contracted by hydrocarbon) is greater than about 25%.
