Abstract
There is provided a catalyst comprising (i) ZSM-5 or ZSM-11, (ii) gallium and (iii) thorium. Also provided is a process for converting ethylene, propylene and/or propane into aromatics with this catalyst. Modification of ZSM-5 with both Ga and Th has been found to result in greater yields of liquid and BTX from a refinery off gas stream than can be obtained with ZSM-5 modified only with Ga.
