    • A method of modifying an alkylation catalyst to reduce the formation of condensed hydrocarbon species thereon. The method comprises providing an alkylation catalyst comprising a plurality of active sites. The plurality of active sites on the alkylation catalyst may include a plurality of weakly acidic active sites, intermediate acidity active sites, and strongly acidic active sites. A base is adsorbed to a portion of the plurality of active sites, such as the strongly acidic active sites, selectively poisoning the strongly acidic active sites. A method of modifying the alkylation catalyst by providing an alkylation catalyst comprising a pore size distribution that sterically constrains formation of the condensed hydrocarbon species on the alkylation catalyst or by synthesizing the alkylation catalyst to comprise a decreased number of strongly acidic active sites is also disclosed, as is a method of improving a regeneration efficiency of the alkylation catalyst.

    • 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 of removing a polar solvent from a fluid volume contaminated with at least one polar impurity, such as a free fatty acid, is provided. The method comprises providing a fluid volume that includes at least one polar impurity dissolved in at least one solvent. The fluid volume is contacted with an expanding gas to remove the at least one solvent. The expanding gas may be dissolved into the at least one solvent in the fluid volume to form a gas-expanded solvent. The immiscibility of the polar impurities in the gas-expanded solvent enables separation of the polar impurities from the gas-expanded solvent. After separation of the polar impurities, at least one of the temperature and pressure may be reduced to separate the solvent from the expanding gas such that the clean solvent may be reused.
    • 提供了从由至少一种极性杂质污染的流体体积如游离脂肪酸中除去极性溶剂的方法。 该方法包括提供包含溶解在至少一种溶剂中的至少一种极性杂质的流体体积。 流体体积与膨胀气体接触以除去至少一种溶剂。 膨胀气体可以溶解在流体体积中的至少一种溶剂中以形成气体膨胀溶剂。 气体膨胀溶剂中的极性杂质的不混溶性使得能够从气体膨胀溶剂中分离极性杂质。 在分离极性杂质之后,可以降低温度和压力中的至少一个以使溶剂与膨胀气体分离,使得清洁溶剂可以重复使用。
