Abstract
An integrated process is provided for producing benzene, toluene, and/or xylene and hydrogen from shale gas under the feeding of carbon dioxide. The integrated process for producing an aromatic compound and hydrogen can efficiently and continuously produce high value-added aromatic compounds and hydrogen without the need to separate methane from shale gas through cryogenic distillation.
Claims18
An integrated process for producing an aromatic compound and hydrogen, which comprises:
- (1) coaromatizing a hydrocarbon feed comprising at least one of methane, ethane, and propane in the presence of a catalyst while feeding carbon dioxide to the hydrocarbon feed or to a reactor in which the coaromatization reaction is carried out to prepare an aromatic compound-containing product comprising at least one of benzene, toluene, and xylene, methane, hydrogen, and carbon monoxide;
- (2) separating from the aromatic compound-containing product (a) hydrogen, (b) the at least one of benzene, toluene, and xylene, and (c) a first methane-containing mixture comprising methane and carbon monoxide, respectively;
- and
- (3) subjecting the carbon monoxide of the first methane-containing mixture to a water-gas shift reaction to prepare a second methane-containing mixture comprising methane, hydrogen, and carbon dioxide.
