摘要： A family of catalysts for oxygen evolution reaction (OER) in alkaline condition is disclosed. The catalysts utilize elements which are abundant on earth, leading to lower costs compared to IrO2 catalysts. The catalysts can be used in the anode of an anion exchange membrane-based water electrolyzer. The family of new catalysts comprises Ni, Fe, M, B, and O, where M is a metal from Group VIB, Group VIII, and elements 57-71 of the Periodic Table. The catalyst has a layered double hydroxide structure. Methods of making the catalysts are also described.

摘要： A new catalyst hydroisomerizes C18 paraffins from fatty acids to a high degree to produce a composition with acceptable freeze point which retains 18 carbon atoms in the hydrocarbon molecule for jet fuel. We have discovered a fuel composition comprising at least 14 wt % hydrocarbon molecules having at least 18 carbon atoms and a freeze point not higher than −40° C. The composition also may exhibit a exhibiting a final boiling point of no more than 300° C. The hydroisomerization process can be once through or a portion of the product diesel stream may be selectively hydrocracked or recycled to hydroisomerization to obtain a fuel composition that meets jet fuel specifications.

摘要： A process for regenerating catalyst from an MTO process is disclosed. The process comprises providing an oxygen stream and a preheated carbon dioxide recycle stream and mixing the oxygen stream and the preheated carbon dioxide recycle stream to provide a carbon dioxide rich oxidation stream. The carbon dioxide rich oxidation stream is passed to a regenerator unit to provide a carbon dioxide rich flue gas stream. The carbon dioxide rich flue gas stream is filtered to remove the catalyst fines to produce a filtered flue gas stream. A carbon dioxide recycle stream is taken from the filtered flue gas stream.

摘要： Processes and apparatuses converting poly- and perfluoroalkyl substances (PFAS). An oxidation reaction zone, preferably a thermal oxidizer, is used to oxidize the PFAS into fluoride species. A reaction zone having at least one reactor containing a solid reactant for neutralizing the fluoride species is provided. The solid reactant is also configured to degrade any PFAS remaining in the effluent from the oxidation zone. A cooling zone, for example, a quench zone may be between the reaction zone and the oxidation zone. The PFAS may be liquid PFAS that is injected into the thermal oxidizer.

摘要： A process for oligomerizing olefins to distillate fuels which oligomerizes a recycle olefin stream with a charge olefin stream in a first-stage oligomerization reactor. The first-stage oligomerate is oligomerized in a second-stage oligomerzation reactor to provide a second-stage oligomerate stream. A recycle olefin stream is taken from said second-stage oligomerate stream.

摘要： A process is provided for preparing a hydrocarbon stream for oligomerization. The process strips dimethyl ether from an olefin stream using a stripping column. Lighter olefins such as C3− olefins are also removed. The C4+ olefins can then be sent for further processing including selective hydrogenation followed by oligomerization.

摘要： A process isolates a liquid hydrocracked stream from a liquid hydroisomerized stream, so heat in the hydrocracked stream can be preserved. Preserving heat in the hydrocracked stream avoids having to reheat the hydrocracked stream before product fractionation. Particularly, kerosene in the hydrocracked stream is not cooled with the hydroisomerized stream and then reheated in fractionation to distill the kerosene range hydrocarbons from the diesel range hydrocarbons.

摘要： A process of treating a feed in an adsorption separation zone comprising at least two adsorbent beds and a trim bed is disclosed. The process comprises displacing feed from a first adsorbent bed to a trim bed by feeding a desorbent from a second adsorbent bed to the first adsorbent bed while displacing spent desorbent from the trim bed. After discontinuing the first adsorbent bed displacement, an adsorber trim fluid to the first adsorbent bed to recover the remaining treated feed in the head. After discontinuing adsorber trim fluid to the first adsorbent bed; a trim displacement fluid is passed to the trim bed to displace feed from the trim bed.

摘要： A process increases the concentration of normal paraffins in a feed stream comprising separating a naphtha feed stream into a normal paraffin rich stream and a non-normal paraffin rich stream. A naphtha feed stream may be separated into a normal paraffin stream and a non-normal paraffin stream. An isomerization feed stream is taken from the non-normal paraffin stream and isomerized over an isomerization catalyst to convert non-normal paraffins to normal paraffins and produce an isomerization effluent stream. The isomerization effluent stream may be separated into a propane stream and a C4+ hydrocarbon stream optionally in a single column. The C4+ hydrocarbon stream may be recycled to the step of separating a naphtha feed stream.
