Embodiment Construction
[0010] The method provided by the invention is specifically implemented as follows: the alkylating agent and the petroleum fraction raw material are premixed in a weight percentage of 0.1 to 99.9, preferably 5 to 45, and then enter the catalyst movable reactor, and the sulfide and alkane in the petroleum fraction are The alkylating agent is in contact with the powdered alkylation catalyst at a temperature of 35°C to 400°C, preferably 90°C to 280°C, a pressure of 0.001MPa to 8MPa, preferably 0.2MPa to 4MPa, and a space velocity of 1h -1 ~4h -1 The alkylation reaction is carried out under certain conditions. At the same time, the alkylating agent can be superimposed to form a component with a higher octane number. The sulfide reacts with the alkylating agent to form a sulfide with a higher boiling point. The reaction product enters the distillation tower Distillation is carried out, the low-sulfur light petroleum fraction is distilled from the top of the tower, and the heavy pet...
