초록 ▼

A process for upgrading topped crude oils and residual portions comprising material boiling above 552°C. (1025°F.) by the combination of partial demetallizing and decarbonizing of the residual oil before effecting zeolite catalytic cracking thereof is described in conjunction with a product separation process, a combined hydrocarbon gas product concentration section and the use of parallel arranged CO boilers to produce sulfur free flue gas and steam. Steam generated by the combination operation effectively reduces the energy requirement of the combustion process.

A method for upgrading high boiling residual portions of crude oils comprising metal contaminants, porphyrins, asphaltenes and high molecular weight multi-ring hydrocarbon material, which method comprises: A. charging a high boiling residual portion of crude oil admixed with diluent in contact with suspended upflowing substantially inert fluidizable solids particulate material at an elevated thermal visbreaking temperature in a riser contact zone for a time sufficient to recover therefrom a vaporous hydrocarbon product higher boiling than gasoline partially decarbonized and demetallized to a lower contaminating metals level, B. quenching said vaporous product of thermal visbreaking below its dew point after separation from solids, C. charging quenched thermally modified high boiling hydrocarbon product comprising metal contaminants in admixture with thermally produced naphtha in contact with a crystalline zeolite cracking catalyst maintained under cracking conditions for a hydrocarbon residence time in a riser cracking zone in the range of 0.5 to 3 second providing a riser outlet product temperature within the range of 510°C. (950°F.) to 593°C. (1100°F.), D. recovering a hydrocarbon conversion product of said zeolite cracking operation comprising gasoline, lower and higher boiling product components separated from catalyst particles, E. separating a combined C4 minus wet gas product stream of said visbreaking and zeolite catalyst cracking operating to recover a C3-C4 rich fraction separately from a C2 minus dry gas product fraction, and F. regenerating said crystalline zeolite containing catalyst comprising carbonaceous deposits of said cracking operating in a sequence of separate regeneration zones provided with catalyst cooling transferred between zones under conditions to produce a CO rich flue as and high temperature catalyst particles suitable for recycle to said zeolite cracking operation; wherein vaporous hydrocarbon products of each said inert solids and catalyst contacting steps comprise naphtha and lower boiling materials which are processed together under conditions to effect the recovery of a C3 minus dry gas stream from a C3-C4 rich gaseous product stream and a naphtha boiling range product separated from a light cycle oil product is used to effect separation of C2 minus products from a C2-C4 rich product stream.
