Abstract:
An integrated process for preparing alkylbenzenes, the process comprising:(a) subjecting syngas to Fischer-Tropsch reaction conditions in the presence of a Fischer-Tropsch catalyst to form a hydrocarbon product stream; (b) isolating a fraction rich in C6-8 hydrocarbons comprising paraffins and olefins and a fraction rich in C18-26 hydrocarbons comprising paraffins and olefins from the hydrocarbon product stream; (c) subjecting the fraction rich in C6-8 hydrocarbons to catalytic reforming conditions to form C6-8 aromatics; (d) optionally subjecting the fraction rich in C18-26 hydrocarbons to dehydrogenation conditions in the presence of a dehydrogenation catalyst to form olefins; and (e) alkylating the C6-8 aromatics with olefins selected from the group consisting of the olefins of step (b) contained in the fraction rich in C18-26 hydrocarbons, the olefins of step (d), or combinations thereof, to form alkylbenzenes.
