Abstract

The conversion of C3/C4 hydrocarbons and higher-boiling hydrocarbon fractions into aromatics-rich products and isobutane is carried out by (a) passing a suspension of a hot regenerated faujasite catalyst in a C3/C4 gaseous hydrocarbon stream at ca. 1250 degrees F through a lower annular portion of a riser reactor for a residence time of 0.1-2 sec.; (b) introducing a higher-boiling hydrocarbon fraction (gas oil or higher) into the suspension at one or more points downstream from the annular zone; (c) passing the suspension through the riser reactor at 900-1000 degrees F for a residence time of =10 sec.; (d) separating the suspension into a hydrocarbon phase and a catalyst phase; and (e) sequentially stripping and regenerating the sepd. catalyst phase. Significant amts. of aromatics and isobutane are produced by cyclisation and H-transfer of the C3/C4 hydrocarbons introduced and those formed by cracking of the heavy hydrocarbon.
