Abstract
1387127 Chemical contact apparatus UNIVERSAL OIL PRODUCTS CO 2 May 1972 [3 May 1971] 20340/72 Heading B1F [Also in Division C5] A catalytic cracking in which both regenerated and unregenerated catalyst are recycled to the reactor riser (b) process comprises (a) cracking a feed stream (1) in contact with a mixture of regenerated catalyst and recycled used catalyst in a riser (6), (b) passing used catalyst, cracked products and any uncracked feed into a separation zone (8), (c) passing part of the used catalyst from the separation zone to a regeneration zone (9) where coke is removed from the catalyst, (d) passing regenerated catalyst from the regeneration zone to the riser (by line 18) to provide the regenerated catalyst for step (a), and (e) passing part of the used catalyst from the separation zone to the riser (by line 5) to provide the recycled used catalyst for a step (a), without mixing of the two catalyst streams outside the riser. As shown, the separation zone 8 includes a fluidized dense bed 16 in which further cracking takes place; both catalyst streams are stripped by gases from lines 19 and 20; and cracked products and spent regeneration gases are taken off by lines 10 and 11 through cyclone separators 12 and 13. Suitable catalysts are zirconia, silica, silica-alumina and zeolite.
