    • A method of reactivating a catalyst, such as a solid catalyst or a liquid catalyst is provided. The method comprises providing a catalyst that is at least partially deactivated by fouling agents. The catalyst is contacted with a fluid reactivating agent that is at or above a critical point of the fluid reactivating agent and is of sufficient density to dissolve impurities. The fluid reactivating agent reacts with at least one fouling agent, releasing the at least one fouling agent from the catalyst. The at least one fouling agent becomes dissolved in the fluid reactivating agent and is subsequently separated or removed from the fluid reactivating agent so that the fluid reactivating agent may be reused. A system for reactivating a catalyst is also disclosed.
    • 提供了重新催化剂如固体催化剂或液体催化剂的方法。 该方法包括提供至少部分由结垢剂去活化的催化剂。 催化剂与处于流体还原剂的临界点以上的流体还原剂接触并且具有足够的密度以溶解杂质。 流体再活化剂与至少一种结垢剂反应,从催化剂中释放至少一种结垢剂。 至少一种结垢剂溶解在流体再活化剂中,随后从流体再活化剂中分离或除去,使得流体再生剂可以重复使用。 还公开了还原催化剂的系统。

    • A method for reactivating a solid alkylation catalyst is provided which can be performed within a reactor that contains the alkylation catalyst or outside the reactor. Effective catalyst reactivation is achieved whether the catalyst is completely deactivated or partially deactivated. A fluid reactivating agent is employed to dissolve catalyst fouling agents and also to react with such agents and carry away the reaction products. The deactivated catalyst is contacted with the fluid reactivating agent under pressure and temperature conditions such that the fluid reactivating agent is dense enough to effectively dissolve the fouling agents and any reaction products of the fouling agents and the reactivating agent. Useful pressures and temperatures for reactivation include near-critical, critical, and supercritical pressures and temperatures for the reactivating agent. The fluid reactivating agent can include, for example, a branched paraffin containing at least one tertiary carbon atom, or a compound that can be isomerized to a molecule containing at least one tertiary carbon atom.
    • 提供了可以在含有烷基化催化剂的反应器中或在反应器外部进行的重新活化固体烷基化催化剂的方法。 无论催化剂是完全失活还是部分失活,都能实现有效的催化剂再活化。 使用流体再活化剂来溶解催化剂污垢剂,并且与这些试剂反应并携带反应产物。 失活的催化剂在压力和温度条件下与流体再生剂接触,使得流体再活化剂足够致密以有效地溶解污垢剂和污垢剂和再活化剂的任何反应产物。 重新激活的有用的压力和温度包括重新激活剂的近临界,临界和超临界压力和温度。 流体再活化剂可以包括例如含有至少一个叔碳原子的支链烷烃,或可以异构化成含有至少一个叔碳原子的分子的化合物。
