摘要： The invention relates to a process for producing LPG and BTX, comprising a) subjecting a mixed hydrocarbon stream to first hydrocracking in the presence of a first hydrocracking catalyst to produce a first hydrocracking product stream; b) separating the first hydrocracking product stream to provide at least a light hydrocarbon stream comprising at least C2 and C3 hydrocarbons, a middle hydrocarbon stream consisting of C4 and/or C5 hydrocarbons and a heavy hydrocarbon stream comprising at least C6+ hydrocarbons and c) subjecting the heavy hydrocarbon stream to second hydrocracking in the presence of a second hydrocracking catalyst to produce a second hydrocracking product stream comprising BTX, wherein the second hydrocracking is more severe than the first hydrocracking, d) wherein at least part of the middle hydrocarbon stream is subjected to C4 hydrocracking optimized for converting C4 hydrocarbons into C3 hydrocarbons in the presence of a C4 hydrocracking catalyst to produce a C4 hydrocracking product stream.

摘要： The invention relates to a process for producing C2 and C3 hydrocarbons, comprising a) subjecting a mixed hydrocarbon feedstream to first hydrocracking in the presence of a first hydrocracking catalyst to produce a first hydrocracking product stream; b) separating the first hydrocracking product stream to provide a light hydrocarbon stream comprising C4− hydrocarbons and c) subjecting the light hydrocarbon stream to C4 hydrocracking in the presence of a C4 hydrocracking catalyst to obtain a C4 hydrocracking product stream comprising C2 and C3 hydrocarbons.

摘要： The invention relates to a process for producing alkylated aromatic hydrocarbons comprising the steps of: (a) subjecting a mixed hydrocarbon feedstream comprising benzene to a separation to provide a C6 cut comprising benzene, wherein the C6 cut comprises at least 60 wt-% of C6 hydrocarbons; (b) subjecting the C6 cut to catalytic cracking or thermal cracking to provide a cracking product stream comprising benzene and C2-C4 alkenes and (c) after step (b), without pre-separation of the cracking product stream, subjecting the cracking product stream to conditions suitable for alkylation to provide an alkylation product stream rich in alkylated aromatic hydrocarbons, wherein the process further comprises the steps of separating benzene and benzene coboilers from the alkylation product stream to obtain a stream of benzene and benzene coboilers and wherein the stream of benzene and benzene coboilers is separated into a benzene-rich stream comprising a higher proportion of benzene than the stream of benzene and benzene coboilers and a benzene-lean stream comprising a lower proportion of benzene than the stream of benzene and benzene coboilers and wherein the benzene-lean stream is recycled back to the catalytic cracking or thermal cracking in step (b).
