Abstract: Provided is a method for producing an alcohol through an olefin hydration reaction using a heteropolyacid catalyst, the method enabling the catalyst to be stably used over a long period. In the olefin hydration reaction, in which the heteropolyacid catalyst is used, the pressure loss during the period of passing a feed-material gas through a catalyst layer is regulated to a certain value or less. Specifically, the method for producing an alcohol comprises using a solid-acid catalyst including a supported heteropolyacid or salt thereof, supplying water and a 2C-5C olefin to a reactor, and hydrating the olefin in a gas phase, wherein the pressure loss during the period of passing the feed-material gas through a layer of the catalyst is regulated to 350 kPa or less.

Abstract: A method for making a supported tantalum oxide catalyst precursor or catalyst with controlled Ta distribution and the resulting supported Ta catalyst. In an embodiment, the method comprises selecting a Ta-precursor with appropriate reactivity with the surface hydroxyls of the solid oxide support material to give a desired Ta distribution in the catalyst precursor or catalyst. In an embodiment the method comprises controlling the number of surface hydroxyls available on the support material to react with the Ta-precursor by thermal methods, such as calcination, to achieve the desired Ta distribution.

Abstract: Embodiments of the present invention relate to two improved catalysts and associated processes that directly convert carbon dioxide and hydrogen to liquid fuels. A catalytic system comprises two catalysts in series that are operated in tandem to directly produce synthetic liquid fuels. The carbon conversion efficiency for CO2 to liquid fuels is greater than 45%. The fuel is distilled into a premium diesel fuels (approximately 70 volume %) and naphtha (approximately 30 volume %) which are used directly as “drop-in” fuels without requiring any further processing. Any light hydrocarbons that are present with the carbon dioxide are also converted directly to fuels. This process is directly applicable to the conversion of CO2 collected from ethanol plants, cement plants, power plants, biogas, carbon dioxide/hydrocarbon mixtures from secondary oil recovery, and other carbon dioxide/hydrocarbon streams. The catalyst system is durable, efficient and maintains a relatively constant level of fuel productivity over long periods of time without requiring re-activation or replacement.

Abstract: Processes for regenerating an at least partially deactivated catalyst that can include a Group (10) element, an inorganic support, and a contaminant. The Group (10) element can have a concentration of from 0.06 wt % to 6 wt %, based on the weight of the inorganic support. The process can include (I) heating the deactivated catalyst using a heating gas mixture that includes H2O at a concentration >5 mol %, based on the total moles in the mixture to produce a precursor catalyst. The process can also include (II) providing an oxidative gas that includes ≤5 mol % of H2O, based on the total moles in the oxidative gas, and (III) contacting the precursor catalyst at an oxidizing temperature with the oxidative gas for a duration of at least 30 seconds to produce an oxidized precursor catalyst. The process can also include (IV) obtaining a regenerated catalyst from the oxidized precursor catalyst.

Abstract: This disclosure relates to a single stage process for the direct conversion of alcohols, e.g. ethanol, to olefinic mixtures (C2-C7) with low levels of aromatics carried out in a single reactor with two fixed catalyst beds in series, or two catalytic fixed bed reactors in series wherein the first reactor operates at a lower or higher temperature than the operating temperature of the second reactor. The process transformation of ethanol is comprised of ethanol dehydration to ethylene and water in high yield with the first catalyst in the first reactor, or via the first fixed catalyst bed, followed by directly feeding the ethylene and water to the second reactor, or second fixed catalyst bed, with conversion of said ethylene and water to a C2-C7 olefinic mixture with the second catalyst(s) in high yields with minimal aromatic compound formation.
