Abstract
Heavy oils are coked in a fluidized system by contacting the oils with fluidized particulate solids at above 1200 DEG F. to produce a vaporous product and a carbonaceous residue which is deposited on the particulate solids, separating the solids from the vaporous product, separating the vaporous product after quenching to obtain at least a naphtha product, a light gas oil fraction boiling below 650 DEG F., and a tar bottoms having an initial boiling point contiguous to the final boiling point of the light gas oil fraction, stripping from the tar bottoms an overhead fraction having a final boiling point below 800 DEG F. and condensing and combining the overhead fraction with a portion of the light gas oil fraction to obtain the liquid quench medium. In a typical example a feed comprising an 1100 DEG F. I.B.P. South Louisiana residuum is fed through a pipe into a transfer line zone, the temperature of which is 1400 DEG F. After approximately 0.75 sec. the reaction mixture is quenched by a liquid medium added through a line, the temperature after quench being 500 DEG F. The quench vapours are separated to obtain 26.8 per cent by weight of naphtha boiling below 430 DEG F., a gas oil fraction boiling from 430 DEG F. to 650 DEG F., and a heavy tar bottoms which is stripped with steam to remove a 650-700 DEG F. fraction which is combined with a larger quantity of the light gas oil fraction which is recycled to the quench point at a temperature of 240 DEG F. as a quench medium. The remainder of the light gas oil fraction amounting to 7.6 per cent by weight on the fresh feed, and of the stripped tar bottoms amounting to 30 per cent by weight are withdrawn as products.
