    Abstract: The present disclosure relates to processes for the alkylation of isoparaffins. A process may include introducing, in a multistage reactor, a solid acid catalyst to an isoparaffin feed and an olefin feed at a pressure of about 300 psig to about 1500 psig to form a alkylation product mixture. A process may also include solid acid catalyst that includes a crystalline microporous material of the MWW framework type. In yet other embodiments, the present disclosure provides for processes for the alkylation of an isoparaffin. A process may include introducing, in a multistage reactor, a solid acid catalyst to an isoparaffin feed and an olefin feed at a temperature of from about 100° C. to about 200° C. to form an alkylation product mixture. A process may further include a solid acid catalyst that includes a crystalline microporous material of the MWW framework type.

    Abstract: The present disclosure is related to processes for the alkylation of an isoparaffin. The process may include introducing, in a multistage reactor, a solid acid catalyst including a zeolite to an isoparaffin feed and an olefin feed to form an alkylation product mixture including C5+ olefins. The processes may further include separating at least a portion of the C5+ olefins from the alkylation product mixture to form an oligomer light stream. The present disclosure further relates to multistage reactors for the alkylation of an isoparaffin with an olefin. The multistage reactors may include a plurality of stages, and a plurality of separation systems. The multistage reactors may also include an outlet space coupling each stage to a separation system and an inlet space coupling a separation system to a subsequent stage.

    Abstract: The present disclosure provides processes for hydroprocessing hydrocarbon feedstocks comprising a silicon content of about 1 wppm or greater. In at least one embodiment, a process includes introducing, in a reactor or to the reactor, a hydrocarbon feedstock having a silicon content of at least about 1 wppm, based on the total weight of the hydrocarbon feedstock, to a treat gas to produce a hydrocarbon feedstock/treat gas mixture. The process includes introducing the hydrocarbon feedstock/treat gas mixture to a catalyst composition comprising at least one group 6 metal and at least one group 8-10 metal, wherein the molar ratio of group 6 metal to group 8-10 metal is from about 10:1 to about 1:10. The process includes obtaining a liquid product comprising a sulfur content of 5,000 wppm or less. Furthermore, processes of the present disclosure provide hydroprocessing of high Si content feeds using hydrocarbon feeds at high liquid hourly space velocities.
