    • A process is disclosed for producing alkyl tertiary alkyl ether such as TAME from alkanol and hydrocarbon feedstock containing linear olefins, iso-olefins, linear alkanes and iso-alkanes such as C5 streams from FCC. The process selectively etherifies iso-olefins in a plural stage etherification zone whose linear olefin-containing effluent is treated by distillation to remove iso-alkanes, and alkanol before passing to a skeletal isomerization zone using constrained intermediate pore size zeolite catalyst such as ZSM-22, ZSM-23, or ZSM-35, which converts linear olefins to iso-olefins which are cycled for etherification. The use of distillation to remove iso-alkanes and alkanol reduces mass flow to the etherification process and minimizes skeletal isomerization catalyst poisoning by alkanol, without resort to water extraction processes which require subsequent treatment of the isomerization zone feed to remove water.
    • 公开了一种从链烷醇生产烷基叔烷基醚如TAME的方法,以及含有直链烯烃,异烯烃,直链烷烃和异烷烃如FCC的C5流的烃原料。 该方法选择性地醚化多级醚化区中的异烯烃,其直链烯烃流出物通过蒸馏处理以除去异烷烃,和链烷醇在使用约束的中等孔径沸石催化剂如ZSM-22进入骨架异构化区之前 ,ZSM-23或ZSM-35,其将线性烯烃转化为异烯烃,其循环用于醚化。 使用蒸馏来除去异烷烃和链烷醇减少了醚化过程的质量流动,并且使骨架异构化催化剂由链烷醇中毒最小化,而不用采用需要随后处理异构化区域进料以除去水的水提取方法。

    • A process for production of dialkyl ether by hydration and etherification of olefinic feedstock containing at least one lower alkene by contacting the olefinic feedstock and water in a catalytic reaction zone with porous solid metallosilicate acidic catalyst under olefin hydration and etherification conditions. Improvement is achieved by recovering a first fluid effluent stream from the reaction zone; splitting the first fluid effluent stream into a liquid product recovery stream and a fluid recycle stream; and passing the fluid recycle stream consisting essentially of olefin, alcohol and ether in effluent stream proportions for feeding to the reaction zone along with fresh olefinic feedstock and fresh water, wherein the amount of fluid recycle stream is sufficient to maintain a homogeneous single fluid reaction phase in the reaction zone.

    • An improved process for production of diisopropyl ether by conversion of hydrocarbon feedstock containing propene, propane and C.sub.2 -- light gas components. The overall process steps include, (optionally) prefractionating fresh feedstock containing propene, propane and C.sub.2 -- light gas components to provide a reactor feedstream rich in propene; contacting the feedstock and water in a catalytic reactor with acidic catalyst under olefin hydration and etherification conditions; and recovering from the catalytic reactor a liquid reactor effluent stream containing diisopropyl ether, isopropanol, water, unreacted propene, propane, oligomer and C.sub.2 -- light gas components. DIPE product containing C.sub.6 + oligomer is recovered by separating the liquid effluent stream in a stripper column, and extracting the DIPE-rich liquid with water. An improved separation process is employed for removing water to provide DIPE liquid product substantially free of water.
