摘要： Disclosed are various embodiments for alkylating olefins and isoparaffins in the presence of an acid to reduce and/or control acid consumption or maximize and/or control the octane number of the produced alkylate product. One embodiment includes alkylation by controlling the C3/iso-C5 olefin ratio to reduce acid consumption. Another embodiment includes alkylation of C3 and C5 olefins in separate alkylation zones to maximize alkylate octane number. Even another embodiment includes propylene alkylation followed by C4 and/or C5 olefin alkylation, with the spent propylene acid used in the C4 and/or C5 olefin alkylation. Still another embodiment includes alkylation of C3, C4 and C5 olefins in separate alkylation zones, with the spent propylene acid used in the C4 alkylation, and the spent butylene acid used in the C5 alkylation. Yet another embodiment includes alkylation by controlling the C3/C4 olefin ratio to maximize the octane number of the produced alkylate.
摘要翻译：公开了在酸存在下烷基化烯烃和异链烷烃以减少和/或控制酸消耗或最大化和/或控制所产生的烷基化产物的辛烷值的各种实施方案。一个实施方案包括通过控制C3 / iso-C5烯烃比率来烷基化以减少酸消耗。另一个实施方案包括在单独的烷基化区烷基化C3和C5烯烃以使烷基化辛烷值最大化。即使另一个实施方案包括丙烯烷基化，随后是C4和/或C5烯烃烷基化，在C4和/或C5烯烃烷基化中使用废丙烯酸。另一个实施方案包括在单独的烷基化区中烷基化C3，C4和C5烯烃，其中用于C4烷基化的废丙烯酸和用于C5烷基化的废丁烯酸。另一个实施方案包括通过控制C3 / C4烯烃比例使烷基化使所产生的烷基化物的辛烷值最大化。

摘要： Disclosed are various embodiments for alkylating olefins and isoparaffins in the presence of an acid to reduce and/or control acid consumption or maximize and/or control the octane number of the produced alkylate product. One embodiment includes alkylation by controlling the C.sub.3 /C.sub.5 olefin ratio to reduce acid consumption. Another embodiment includes alkylation of C.sub.3 and C.sub.5 olefins in separate alkylation zones to maximize alkylate octane number. Even another embodiment includes propylene alkylation followed by C.sub.4 and/or C.sub.5 olefin alkylation, with the spent propylene acid used in the C.sub.4 and/or C.sub.5 olefin alkylation. Still another embodiment includes alkylation of C.sub.3, C.sub.4 and C.sub.5 olefins in separate alkylation zones, with the spent propylene acid used in the C.sub.4 alkylation, and the spent butylene acid used in the C.sub.5 alkylation. Yet another embodiment includes alkylation by controlling the C.sub.3 /C.sub.4 olefin ratio to maximize the octane number of the produced alkylate.
