摘要： The C2 to C5 and heavier acetylenes and dienes in a thermally cracked feed stream are hydrogenated without significantly hydrogenating the C2 and C3 olefins. Additionally, the C4 and heavier olefins may be hydrogenated. Specifically, the cracked gas feed in an olefin plant is hydrogenated in a distillation reaction column containing a hydrogenation catalyst without the necessity of separating the hydrogen out of the feed and without any significant hydrogenation of the ethylene and propylene. A combined reaction-fractionation step known as catalytic distillation hydrogenation is used to simultaneously carry out the reactions and separations while maintaining the hydrogenation conditions such that the ethylene and propylene remain substantially unhydrogenated and essentially all of the other C2 and heavier unsaturated hydrocarbons are hydrogenated. Any unreacted hydrogen can be separated by a membrane and then reacted with separated C9 and heavier materials to produce hydrogenated pyrolysis gasoline.

摘要： A process for removing dienes from etherification uses a hydrogenation zone (24) in the reactor distillation column (20) above the etherification zone (22). MTBE is produced and the unreacted C4 stream is also subjected to selected hydrogenation of the butadiene contained in the C4 feed stream. The C4 stream is introduced via line (101) and methanol is introduced via line (102) which is combined in flow line (104) and subsequently enters the distillation column (20) via line (103) wherein the C4 stream is contacted with methanol in the etherification zone (22) where the MTBE is distilled downward. The unreacted C4's then are subjected to selective hydrogenation in the hydrogenation zone (24) wherein butadiene in the overhead raffinate (108) is reduced by over 90 %. The hydrotreated C4's are thus suitable for cold acid alkylation or other use wherein butadiene is harmful.
摘要翻译：用于从醚化中除去二烯的方法在醚化区（22）上方的反应器蒸馏塔（20）中使用氢化区（24）。生产MTBE，并且还对未反应的C4物流进行C4进料流中包含的丁二烯的选择氢化。经由管线（101）引入C4流，并且经由管线（102）引入甲醇，该管线（102）在流动管线（104）中组合，随后通过管线（103）进入蒸馏塔（20），其中C4流体与甲醇接触在醚化区（22）中，MTBE向下蒸馏。然后在氢化区（24）中对未反应的C4进行选择性氢化，其中塔顶残液（108）中的丁二烯减少超过90％。因此，加氢处理的C4适合于冷酸烷基化或丁二烯有害的其它用途。

摘要： A process for the hydrogenation of unsaturated cyclic and polycyclic compounds to saturates is provided wherein the reactor is operated at a pressure wherein the reaction mixture is boiling under low hydrogen partial pressure in the range of about 0.1 psi to less than 70 psia at 0 to 350 psig. The catalyst is provided as a catalytic distillation structure such that the reaction is concurrently occurring with a distillation. A portion of the overheads is returned as reflux to provide cooling within the catalyst bed and concurrent condensation of some of the gaseous material within the bed. Although no separation is obtained all of the advantages of concurrent reaction with distillation are achieved.
