Abstract: A method for desalinating a liquid, including: contacting, within a hydrate former reactor, a feed gas stream including iso-butane in an amount ranging from above zero mol % to about 3 mol % and liquid seawater or liquid wastewater including a dissolved salt, wherein a temperature and pressure within the hydrate former reactor is controlled so that the feed gas stream and the liquid seawater or liquid wastewater form a hydrate slurry; separating hydrate particles from the hydrate slurry; and decomposing the hydrate particles into its constituents of water and gas or gas mixture containing iso-butane, wherein the water has a concentration of the dissolved salt that is less than that of the liquid seawater or liquid wastewater.

Abstract: In a process for the catalytic alkylation of an olefin with an isoparaffin, an olefin-containing feed is contacted with an isoparaffin-containing feed under alkylation conditions in the presence of a solid acid catalyst comprising a crystalline microporous material of the MWW framework types, wherein the olefin-containing feed consists essentially of pentenes.

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 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: A method for removing gas contaminants from flowing solids in a fluid catalytic cracking (FCC) process can include: catalytically cracking a hydrocarbon feedstock in the presence of a catalyst in a riser of a FCC unit to produce a hydrocarbon product; separating the hydrocarbon product from a spent catalyst to produce a hydrocarbon product stream; regenerating the spent catalyst in a regeneration gas comprising oxygen to produce a mixture comprising a regenerated catalyst and a gas contaminant at a first concentration; introducing a stripping gas and the mixture into a regenerated catalyst stripper to produce a regenerated catalyst stream comprising the regenerated catalyst, the stripping gas, and a gas contaminant at a second concentration that is reduced by 50% or greater as compared to the first concentration; and introducing the regenerated catalyst stream to the riser.
