摘要： The specification discloses a method for cleaning an oligomerization reactor after making a higher olefin in the reactor. An olefin is reacted in the presence of a catalyst comprising an aluminum alkyl to form an olefin reaction product. For example, ethylene can be trimerized in the reaction to produce 1-hexene. The reaction also causes a co-product residue of the catalyst to form on the interior surface of the reactor. The interior surface of the reactor is then contacted with an alcohol under conditions effective to remove at least a substantial amount of the catalyst residue from the interior surface of the reactor. The catalyst-removing step can be carried out by combining an alcohol with the process medium used in the reactor. The combined medium can be used to remove both the accumulated polymer co-product and the accumulated catalyst residue from the reactor.
摘要翻译：该说明书公开了在反应器中制备高级烯烃之后清洗低聚反应器的方法。烯烃在包含烷基铝的催化剂的存在下反应以形成烯烃反应产物。例如，乙烯可以在反应中进行三聚，以产生1-己烯。该反应还导致催化剂的副产物残余物在反应器的内表面上形成。然后在有效地从反应器的内表面除去至少大量催化剂残余物的条件下，将反应器的内表面与醇接触。催化剂除去步骤可以通过将醇与反应器中使用的加工介质结合来进行。组合的介质可用于从反应器中除去累积的聚合物共同产物和累积的催化剂残余物。

摘要： The present invention provides a method and apparatus for reforming a hydrocarbon feedstock in the presence of steam using a steam-active reforming catalyst The present invention can generally be used in conjunction with any steam-active reforming processes wherein the hydrocarbon reforming and catalyst regeneration operations are conducted simultaneously and the catalyst is regenerated using a steam-diluted oxygen (or air) regeneration medium. In the present invention, catalyst regeneration effluent gas is advantageously reused in the reforming operation to provide at least a portion of the steam environment required for reforming the hydrocarbon feedstock. Free oxygen is preferably removed from the regeneration effluent gas before the regeneration effluent gas is brought into contact with the hydrocarbon feedstock.
