摘要:A process for synthesis of lower isoparaffins from synthesis gas that is a mixture of hydrogen and carbon monoxide, wherein straight chain hydrocarbons are synthesized while isoparaffins and isoolefins are also produced through decomposition of hydrocarbons having a higher carbon number by use of a solid acid catalyst in the first stage, and isoparaffins are synthesized in the second stage. The straight chain hydrocarbons are produced by contacting the synthesis gas with a Fischer-Tropsch synthesis catalyst that is mixed with a solid acid catalyst for mainly hydrocracking long chain hydrocarbons. The isoparaffins are produced by contacting the straight chain hydrocarbons synthesized in the first stage, with a mixture of a hydrogenation catalyst for hydrogenating olefins and a solid acid catalyst for hydrocracking and isomerizing the straight chain hydrocarbons.

摘要:The present invention provides a method for the continuous synthesis of a substituted benzoic-acid organic substance. The continuous synthesis method comprises: in the presence of catalyst and organic solvent, the organic matter represented by formula (I) and oxygen are continuously inputted to a continuous reaction apparatus for continuous oxidation reaction to obtain a substituted benzoic-acid organic substance, which is discharged continuously, the substituted benzoic-acid organic substance having the structure represented by formula (II). Oxygen is a green reagent and is inexpensive and readily available; a large amount of wastewater, waste gas, and solid waste is not generated after the reaction, and the system is easy to handle. The use of a continuous reaction operation can reduce the risk of flash distillation and explosion of solvent due to a high concentration of oxygen in a batch reaction. Under the same oxidation conditions, the continuous preparation process can reduce the escape of oxygen, greatly increasing the oxygen utilization rate and also simplifying the operation, improving the safety of the reaction and the yield of the substituted benzoic-acid organic substance.

摘要:The present invention provides: a production process for a catalyst for synthesis of an unsaturated aldehyde and/or an unsaturated carboxylic acid, which production process is suitable for producing the catalyst with good reproducibility, wherein the catalyst is excellent in activity, selectivity, and physical strength; this catalyst; and a production process for the unsaturated aldehyde and/or the unsaturated carboxylic acid by using this catalyst. The production process for the catalyst comprises the steps of: carrying out heat treatment of an aqueous solution or slurry of a starting material to thus prepare a catalyst precursor P1, wherein the starting material includes molybdenum, bismuth, and iron as essential components; thereafter adding and mixing a binder into the P1 to thus prepare a catalyst precursor P2; and molding and then calcining the P2, thereby producing the catalyst for synthesis of the unsaturated aldehyde and/or the unsaturated carboxylic acid; with the production process being characterized by involving an ignition loss ratio of the catalyst precursor P1 in the range of 10 to 40 mass % (excluding 40 mass %).
