    摘要： 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.

    摘要： The present invention relates to a process for converting a feed comprising C2-C4 alkanes to higher hydrocarbon(s) including aromatic hydrocarbon(s) in n reaction zones operated in series, wherein m reaction zones are not participating in the conversion process and only (n-m) reaction zones are operated under reaction conditions sufficient to convert at least a portion of said a feed comprising C2-C4 alkanes to an effluent having said higher hydrocarbon(s). An object of the present invention is to provide a process for converting LPG to higher hydrocarbon(s) including aromatic hydrocarbon(s) wherein a high reactant, i.e. ethane, propane and/or butane, conversion can be achieved.
