    • A process for the production of a high quality gasoline blending components from refinery process streams by the alkylation of light isoparafflns with olefins using an ionic liquid catalyst is disclosed. The alkylation process comprises contacting a hydrocarbon mixture comprising at least one olefin having from 2 to 6 carbon atoms and at least one isoparaffin having from 3 to 6 carbon atoms under alkylation conditions, said catalyst comprising a mixture of at least one acidic ionic liquid and at least one alkyl halide. In one embodiment, the acidic ionic liquid is chloroaluminate ionic liquid prepared by mixing aluminum trichloride (AlCl 3 ) and a hydrocatbyl substituted pyridinium halide, a hydrocarbyl substituted imidazolium halide, trialkylammonium hydrohalide or tetraalkylammonium halide of the general formulas (A), (B), (C) and (D), respectively, where R=H, methyl, ethyl, propyl, butyl, pentyl or hexyl group and X is a halide and preferably a chloride, and R 1 and R 2 =H, methyl, ethyl, propyl, butyl, pentyl or hexyl group and where R 1 and R 2 may or may not be the same, and R 3 , R 4 and R 5 and R 6 =methyl, ethyl, propyl, butyl, pentyl or hexyl group and where R 3 , R 4 , R 5 and R 6 may or may not be the same.
    • 公开了一种通过使用离子液体催化剂将轻质异链烷烃与烯烃烷基化从炼油厂工艺物流生产高品质汽油共混组分的方法。 该烷基化方法包括使包含至少一种具有2至6个碳原子的烯烃和至少一种具有3至6个碳原子的异链烷烃的烃混合物在烷基化条件下接触,所述催化剂包含至少一种酸性离子液体和 至少一种烷基卤化物。 在一个实施方案中,酸性离子液体为通过混合三氯化铝(AlCl 3)和卤代烃基取代的吡啶鎓盐,烃基取代的咪唑鎓卤化物,三烷基铵氢卤化物或四烷基铵卤化物制备的氯铝酸盐离子液体, (其中R = H,甲基,乙基,丙基,丁基,戊基或己基,X是卤素并且优选氯化物)和R(R) 1和R 2 = H,甲基,乙基,丙基,丁基,戊基或己基,并且其中R 1和R 2独立地选自 >可以是也可以不是相同的,并且R 3 ,R 4 和R 5 和R 6 = 甲基,乙基,丙基,丁基,戊基或己基,并且其中R 3,R 4,R 5,R 6, / SUB>可能相同也可能不相同。
