摘要:A catalyst and process for synthesis of dimethyl ether from synthesis gas are disclosed. The catalyst and process allow dimethyl ether synthesis at low pressures (below 20 bars) at a conversion rate close to the expected equilibrium rate. The catalyst is a combination of a methanol synthesis catalyst with metal components comprising Cu, Zn, Al, Mn and Cs and a methanol dehydration catalyst, wherein the dehydration catalyst is a dehydration agent which allows optimum production of dimethyl ether.

摘要:There is provided macrostructures of porous inorganic material which can have controlled size, shape, and/or porosity and a process for preparing the macrostructures. The macrostructures comprise a three-dimension network of particles of porous inorganic materials. The process for preparing the macrostructures involves forming an admixture containing a porous organic ion exchanger and a synthesis mixture capable of forming the porous inorganic material and then converting the synthesis mixture to the porous inorganic material. After formation of the composite material, the porous organic ion exchanger can be removed from the composite material to obtain the macrostructures.

摘要:A catalyst composition which contains at least one metal from Group 2b and at least one metal from Group 6b of the Periodic Table of the Elements or compounds thereof and a crystalline aluminum silicate which is obtained by crystallizing an aqueous alkaline starting mixture comprising at least one silicon compound, at least one aluminum compound, at least one compound of a metal from Group 1a of the Periodic Table of the Elements (MX) and organic nitrogen compounds at an elevated temperature until said crystalline aluminum silicate is formed and subsequently separating crystalline aluminum silicate from the mother liquor, in which starting mixture the compounds are present in the following molar ratios: RN: R4NY=1-1000, SiO2: R4NY=10-5000, SiO2: Al2O3=50-300, SiO2: MX<15, and H2O: SiO2=5-100, where RN represents a pyridine and R4NY represents an organic quaternary ammonium compound. The catalyst composition can be used in a process for the preparation of hydrocarbons from synthesis gas.

摘要:There is provided a catalyst containing porous macrostructures comprised of: (a) a three-dimensional network of particles of porous inorganic material (e.g., zeolites); and, (b) at least one metal (e.g., a catalytically active metal). The particles of the at least one macrostructure occupy less than 75% of the total volume of the at least one macrostructure and are jointed together to form a three-dimensional interconnected network. The three-dimensional interconnected network will usually be comprised of pores having diameters greater than about 20 Ã…. The macrostructures can be made by forming an admixture containing a porous organic ion exchanger (e.g., a polymer-based ion exchange resin) and a synthesis mixture (e.g., for zeolite formation) capable of forming the porous inorganic material and the at least one metal; converting the synthesis mixture to the porous inorganic material; and removing the porous organic ion exchanger from the inorganic material. The metal-containing macrostructures find application in hydrocarbon conversion (e.g., hydrogenation, dehydrogenation, dehydrocyclization, isomerization, hydrocracking, dewaxing, reforming, conversion of alkyl aromatics, etc.) and in the reduction of emissions of hydrocarbons, carbon monoxide, and/or oxides of nitrogen from an internal combustion engine.
