Abstract
The invention relates to a process for hydrocracking a feedstream comprising hydrocarbons to obtain BTX in a gas phase hydrocracking reactor system which comprises (i) an upstream end and a downstream end, (ii) a plurality of successive reaction zones distributed along the reactor between the upstream end and the downstream end, wherein each of the reaction zones has a bed of a hydrocracking catalyst contained therein and (iii) a plurality of quench zones, the quench zones being distributed along the reactor and each being situated between successive reaction zones, wherein the process comprises: (a) injecting a first portion of a hydrogen gas into the upstream end and a first portion of a hydrocarbon gas into the upstream end and (b) injecting a second portion of the hydrogen gas into at least one of the quench zones and injecting a second portion of the hydrocarbon gas into at least one of the quench zones, wherein the molar ratio between hydrogen and hydrocarbons entering each of the reaction zones is 1:1 to 4:1, wherein the molar ratio between hydrogen and hydrocarbons entering the reaction zones decreases with the distance of the reaction zone from the upstream end of the reactor.
