Patent ID: 8309778

Claim:
A process for producing light aromatic hydrocarbons and light alkanes from hydrocarbonaceous feedstock, comprising the following steps: (a) introducing hydrogen and a hydrocarbonaceous feedstock having boiling point in range of 30-250° C. into at least one reaction zone; (b) converting the hydrocarbonaceous feedstock to an effluent enriched in light aromatic hydrocarbons of benzene, toluene and xylene and light alkanes in the reaction zone in the presence of a catalyst, wherein of the hydrocarbonaceous feedstock the heavy aromatic hydrocarbons are subjected to hydrodealkylation and/or transalkylation with light aromatic hydrocarbon, the light aromatic hydrocarbons are subjected to isomerization and the non-aromatic hydrocarbons are subjected to hydrocracking reaction, and the catalyst comprises metallic Pt and/or Pd supported on a binder-free zeolite for producing light aromatic hydrocarbons and light alkanes from hydrocarbonaceous feedstock, wherein the amount of metallic Pt and/or Pd is of 0.01-0.8 wt % on the basis of the total weight of the catalyst, and the binder-free zeolite is selected from the group consisting of mordenite, beta zeolite, Y zeolite, ZSM-5, ZSM-11 and composite or cocrystal zeolite thereof; and (c) recovering the light aromatic hydrocarbons and the light alkanes respectively by passing the effluent through gas-liquid separation and distillation sequentially, and the separated heavy fraction is recycled to the reaction zone for further reaction.
