摘要：
A method of converting methanol into gasoline is disclosed. A stream of methanol at is received at a gasoline production facility. The stream is split into a first stream for use in a methanol to gasoline (MTG) facility and a second stream for use in a methanol to olefin (MTO) facility. The first stream of methanol is converted using a methanol to gasoline process to produce a first stream of gasoline blend stock and a stream of light non-quaternary isoparaffins. The second stream of methanol is converted using a methanol to olefin process to produce a stream of light olefins selected from the group consisting of ethylene, propylene, butenes and combinations thereof. At least a portion of the stream of light non-quaternary isoparaffins is alkylated with at least a portion of the stream of light olefins to produce at least one alkylate. At least a portion of the alkylate is blended with at least a portion of the first stream gasoline blend stock to form a second stream of gasoline blend stock. In one embodiment, the alkylation process uses an ionic liquid catalyst capable of alkylating ethylene.
摘要（中）：
公开了一种将甲醇转化成汽油的方法。 在汽油生产设施处接收甲醇流。 流被分成用于甲醇 - 汽油（MTG）设备的第一流和用于甲醇 - 烯烃（MTO）设施的第二流。 使用甲醇将第一流甲醇转化成汽油过程以产生第一流的汽油共混料和轻质非四级异链烷烃流。 使用甲醇转化为烯烃方法将第二甲醇流转化成产生选自乙烯，丙烯，丁烯及其组合的轻质烯烃物流。 将至少一部分轻质非正构烷烃与至少一部分轻质烯烃流烷基化以产生至少一种烷基化物。 将烷基化物的至少一部分与至少一部分第一流汽油混合原料混合以形成第二汽油混合原料料流。 在一个实施方案中，烷基化方法使用能够使乙烯烷基化的离子液体催化剂。
