PROCESS FOR PRODUCING BTX FROM A C5-C12 HYDROCARBON MIXTURE |
摘要 |
The present invention relates to a process for producing chemical grade BTX from a mixed feedstream comprising C5-C12 hydrocarbons by contacting said feedstream in the presence of hydrogen with a catalyst having hydrocracking/hydrodesulphurisation activity. Particularly, a process for producing BTX from a feedstream comprising C5-C12 hydrocarbons is provided comprising the steps of: (a) contacting said feedstream in the presence of hydrogen with a combined hydrocracking/hydrodesulphurisation catalyst to produce a hydrocracking product stream comprising BTX; and (b) separating the BTX from the hydrocracking product stream. The hydrocracking/hydrodesulphurisation catalyst comprises 0.1-1 wt-% hydrogenation metal in relation to the total catalyst weight. The hydrocracking/hydrodesulphurisation catalyst further comprises a zeolite having a pore size of 5-8 Å and a silica (SiO2) to alumina (Al2O3) molar ratio of 5-200. The hydrocracking/hydrodesulphurisation conditions include a temperature of 450-580° C., a pressure of 300-5000 kPa gauge and a Weight Hourly Space Velocity of 0.1-10 h−1. |

1. Process for producing BTX comprising:
(a) contacting a feedstream comprising C5-C12 hydrocarbons in the presence of hydrogen with a hydrocracking/hydrodesulphurisation catalyst comprising 0.1-1 wt-% hydrogenation metal in relation to the total catalyst weight and a zeolite having a pore size of 5-8 Å and a silica (SiO2) to alumina (Al2O3) molar ratio of 5-200 under process conditions comprising a temperature of 450-580° C., a pressure of 300-5000 kPa gauge and a Weight Hourly Space Velocity of 0.1-10 h−1 to produce a hydrocracking product stream comprising BTX; and (b) separating the BTX from the hydrocracking product stream. |
