Abstract:
The invention relates to a process for producing C2 and C3 hydrocarbons, comprising a) subjecting a mixed hydrocarbon carbon stream comprising a middle distillate to first hydrocracking in the presence of a first hydrocracking catalyst to produce a first hydrocracking product stream, b) subjecting a second hydrocracking feed stream to second hydrocracking in the presence of a second hydrocracking catalyst to produce a second hydrocracking product stream, wherein the second hydrocracking is more severe than the first hydrocracking and c) subjecting a C4 hydrocracking feed stream to C4 hydrocracking optimized for converting C4 hydrocarbons into C3 hydrocarbons in the presence of a C4 hydrocracking catalyst to obtain a C4 hydrocracking product stream, wherein the C4 hydrocracking is more severe than the second hydrocracking, wherein the first hydrocracking product stream, the second hydrocracking product stream and the C4 hydrocracking product stream are fed to a separation system which provides —the second hydrocracking feed stream separated from the first hydrocracking product stream, —the C4 hydrocracking feed stream separated from the second hydrocracking product stream, —a first recycle stream to be recycled back to the first hydrocracking, —a second recycle stream to be recycled back to the second hydrocracking, —a third recycle stream to be recycled back to the C4 hydrocracking, —a hydrogen recycle stream of H2 or H2 and C1 to be recycled back to the first hydrocracking, the second hydrocracking and/or the C4 hydrocracking and —a C2 and C3 product stream of C3− hydrocarbons, wherein the second hydrocracking feed stream is a stream of C12− hydrocarbons excluding C10-C12 hydrocarbons having di-ring structures, wherein the first recycle stream is a stream of C13+ and C10-C12 hydrocarbons having di-ring structures, wherein the C4 hydrocracking feed stream is a stream of C5−, C4− or iC4−, wherein the second recycle stream is a stream of C6+, C5+ or nC4+ 30 wherein the third recycle stream is a stream of nC4+ or C4+.

Claim (Index 2):
The process according to  claim 1 , comprising\n a) subjecting a mixed hydrocarbon stream comprising a middle distillate to first hydrocracking in the presence of a first hydrocracking catalyst to produce a first hydrocracking product stream, a1) subjecting the first hydrocracking product stream to one or more separation steps to obtain\n the second hydrocracking feed stream of C12\u2212 hydrocarbons excluding C10-C12 hydrocarbons having di-ring structures and a heavy first hydrocracking product stream of C13+ and C10-C12 hydrocarbons having di-ring structures, \n a2) recycling at least part of the heavy first hydrocracking product stream to step a), b) subjecting a second hydrocracking feed stream to second hydrocracking in the presence of a second hydrocracking catalyst to produce a second hydrocracking product stream, wherein the second hydrocracking is more severe than the first hydrocracking, b1) subjecting the second hydrocracking product stream to one or more separation steps to obtain\n the C4 hydrocracking feed stream of C5\u2212 hydrocarbons and a heavy second hydrocracking product stream of C6+ hydrocarbons, \n the C4 hydrocracking feed stream of C4\u2212 hydrocarbons and a heavy second hydrocracking product stream of C5+ hydrocarbons or \n the C4 hydrocracking feed stream of iC4\u2212 hydrocarbons and a heavy second hydrocracking product stream of nC4+ hydrocarbons \n b2) recycling at least part of the heavy second hydrocracking product stream to step b), c) subjecting a C4 hydrocracking feed stream to C4 hydrocracking in the presence of a C4 hydrocracking catalyst to produce a C4 hydrocracking product stream, wherein the C4 hydrocracking is more severe than the second hydrocracking, c1) subjecting the C4 hydrocracking product stream to one or more separation steps to obtain\n a light C4 hydrocracking product stream of iC4\u2212 hydrocarbons and a heavy C4 hydrocracking product stream of nC4+ hydrocarbons or \n a light C4 hydrocracking product stream of C3\u2212 hydrocarbons and a heavy C4 hydrocracking product stream of C4+ hydrocarbons and \n c2) recycling at least part of the heavy C4 hydrocracking product stream to step c).
