摘要： A process for thermally and catalytically upgrading a heavy feed in a single riser reactor FCC unit is disclosed. A heavy feed is added to a blast zone in the base of the riser, and sufficient hot regenerated FCC catalyst is added to induce both thermal and catalytic cracking of the heavy feed. A reactive quench material, which cools the material discharged from the blast zone is added to a quench zone downstream of the blast zone, to reduce temperature at least in part by undergoing endothermic reactions in the riser. Quench liquids can be distillable FCC feeds such as gas oil, slack wax, or alcohols or ethers. The quench material is added in an amount equal to 100 to 1000 wt % of the non-distillable material in the heavy feed. A preferred catalyst, with a high zeolite content, is used which retains activity in the quench despite initial contact with the heavy feed, which tends to overwhelm conventional FCC catalysts.

摘要： Modified ZSM-5 type zeolite catalyst is prepared by controlled aging in a moving bed catalytic cracking unit. The modified catalyst exhibits significant olefin isomerization activity and reduced paraffin cracking activity. Hydrocarbons are cracked to products boiling in the motor fuel range, e.g., gasoline, by using the modified catalyst mixture comprising a ZSM-5 type zeolite and a conventional cracking catalyst. The ZSM-5 type zeolite is treated with partial pressure steam under conditions which increase the gasoline octane number of the product fuel without decreasing gasoline plus distillate yield. A process for changing a catalytic cracking unit's inventory from a conventional catalyst to a modified ZSM-5 type containing catalyst is also disclosed.

摘要： The invention combines two unit operations i.e. fluid catalytic cracking (FCC) and circulating fluid bed (CFB) boiler technologies. The circulating solid inventory of the CFB boiler is introduced to the bottom of a conventional FCC unit to supply the endothermic heat of reaction. A once-through FCC catalyst is introduced under high-temperature, short residence time conditions whereby improved yields are achieved through the reduction of coke made in the FCC unit.
