Abstract: A method for catalytic synthesis of ammonia under normal pressures, including: performing a reaction of hydrogen and nitrogen to synthesize ammonia under normal pressures by taking a liquid alloy as a catalyst in a reactor, where the reactor contains a molten salt, the density of the molten salt is smaller than that of the liquid alloy, and the molten salt is used for providing a reaction interface and isolating the liquid alloy from being introduced impurities. The first metal reacts with the nitrogen to produce the metal nitride, and the molten salt provides a new reaction interface for the metal nitride to react with the hydrogen to synthesize ammonia, so that ammonia is produced continuously. In addition, the molten salt prevents the liquid alloy from contacting with the oxygen and the water vapor, which prevents the liquid alloy from being oxidized, thus prolonging its service life.

Abstract: A catalyst includes a support, where the support includes an external surface, about 60 wt % to about 99 wt % silica, and about 1.0 wt % to about 5.0 wt % alumina. A catalytic layer is disposed within the support adjacent to the external surface, where the catalytic layer further includes Pd, Au, and potassium acetate (KOAc). In the catalyst, (a) the KOAc is from about 60 kg/m3 to about 150 kg/m3 of the catalyst; or (b) the catalytic layer has an average thickness from about 50 μm to about 150 μm; or (c) both (a) and (b). The catalyst also possesses a Brunauer-Emmett-Teller surface area of about 130 m2/g to about 300 m2/g and a geometric surface area per packed bed volume from about 550 m2/m3 to about 1500 m2/m3. The catalyst is highly active for the synthesis of vinyl acetate monomer and exhibits a high selectivity for vinyl acetate monomer.

Abstract: The addition of small amounts of alkaline earth metal oxides (CaO, MgO) as the isomerization function and transition metal oxides (such as MoO3, WO3) as the metathesis function significantly enhances the production of propylene using zeolites. Once the light olefins are formed by cracking on the acid sites of the zeolite, the 1-butene molecules undergo isomerization catalyzed by alkali earth metal oxides and then react with ethylene to produce more propylene.

Abstract: A porous material structure and device are described and shown to enhance the mass transfer and/or heat transfer at low pressure drops for removal of certain molecular species from a fluid by adsorption and/or catalytic reaction. The porous structure of active materials comprising packed fine particles of adsorbents or catalysts is encapsulated with a thin membrane to provide large interfacing area with the fluid per unit volume for rapid mass transfer between the porous structure and fluid. The thin membrane also blocks particulate from getting into the porous structure of the active material. For the process involving significant heat of adsorption and/or reaction, the another surface of the porous structure of the active material is encapsulated with a thin non-permeable sheet to interface with a thermal fluid for rapid heat transfer between the porous structure and the thermal fluid. The device can be used for removal of CO2, moisture, and hydrocarbon molecules from a gas stream with rapid in-situ regeneration. The device can be used for removal of water from water-containing liquid fluids, such as solvents and oils. The device can be used for removal of bacteria, virus, salts, and molecular contaminants from one water simultaneously.

Abstract: A process for converting a hydrocarbon feed includes contacting a hydrocarbon feed with steam in the presence of a cracking catalyst under steam enhanced catalytic cracking conditions. The contacting the hydrocarbon feed with the steam in the presence of the cracking catalyst causes at least a portion of the hydrocarbon feed to undergo steam catalytic cracking reactions to produce a cracked effluent comprising C2 to C4 olefins, C6 to C10 aromatic compounds, or both. The cracking catalyst is a nanoparticle. The nanoparticle has a core and a shell. The core includes at least one zeolite particle, where the at least one zeolite particle includes ZSM-5 zeolites, Beta zeolites, Y-zeolites, or combinations of these zeolites. The shell is mesoporous and incudes silica (SiO2), alumina (Al2O3), or silica and alumina.

Abstract: Processes for converting a hydrocarbon reactant into an alcohol compound and/or a carbonyl compound are disclosed in which the hydrocarbon reactant and a supported transition metal catalyst—containing molybdenum, tungsten, or vanadium—are irradiated with a light beam at a wavelength in the UV-visible spectrum, optionally in an oxidizing atmosphere, to form a reduced transition metal catalyst, followed by hydrolyzing the reduced transition metal catalyst to form a reaction product containing the alcohol compound and/or the carbonyl compound.
