The present invention relate to processes for converting olefins to alcohols, ethers, or combinations thereof that are suitable for use as a gasoline additive. In one embodiment, the process comprises (a) receiving a feed stream, wherein the feed stream comprises one or more olefins having 2 to 5 carbon atoms in an amount of up to 80% by weight based on the weight of the feed stream; (b) hydroformylating the feed stream in the presence of a catalyst to convert at least 80% of the olefins from the feed stream to oxygenates; (c) separating a product stream from step (b) into an oxygenate stream and a stream comprising unreacted olefins, inerts, the catalyst, and the remaining oxygenates; and (d) treating the oxygenate stream to convert a plurality of the oxygenates into at least one of an alcohol, an ether, or combinations thereof is suitable for use as a gasoline additive.
本发明涉及将烯烃转化为适合用作汽油添加剂的醇、醚或其组合的工艺。在一个实施方案中,该工艺包括:(a) 接收进料流,其中进料流包含一种或多种具有 2 至 5 个碳原子的烯烃,其含量为进料流重量的 80%;(b) 在催化剂存在下对进料流进行加氢甲酰化,将进料流中至少 80%的烯烃转化为含氧化合物;(c) 将来自步骤(b)的产品流分离为含氧化合物流和包含未反应烯烃、惰性物质、催化剂和剩余含氧化合物的流;以及 (d) 处理含氧化合物流,将多种含氧化合物转化为醇、醚或其组合中至少一种适合用作汽油添加剂的物质。
