摘要: A method for producing a multiphase mixed-oxide catalyst including at least one active phase based on bismuth molybdate and one co-catalyst based on iron molybdate and at least one amongst the two elements cobalt and nickel, includes the following steps:
preparing a mixture of the precursors of said-mixed oxides in a solvent,
making said precursors react through a microwave-assisted hydrothermal reaction, and
isolating the mixed oxides to obtain the catalyst.
A catalyst and a catalytic system prepared in this manner are related to the method as well as the uses of this catalyst and of this catalytic system, in particular in the oxidation of propene into acrolein.-

摘要: Selective recovery of C2 to C4 hydrocarbons is achieved through the use of a converging-diverging nozzle, or de Laval nozzle. The vapor stream comprising C2 to C4 hydrocarbons is fed into an inlet of a de Laval nozzle having a throat. The vapor stream may have an initial temperature of between 0° C. and 100° C., and an initial pressure of between 200 psig and 500 psig. In the de Laval nozzle, the vapor stream expands after passing through the throat of the de Laval nozzle, producing a vapor stream having re-duced temperature and pressure. Then, C2 to C4 hydrocarbons condense from the reduced-temperature vapor stream as liquid droplets, which may be recovered. Fractionation of C2 to C4 hydrocarbons by means of a de Laval nozzle is possible; the technique allows select-ive recovery of propane from a mixture of propane and ethane.

摘要: The first aspect of the present invention is intended to provide a method for producing an oxidation reaction product of the hydrocarbon or a derivative thereof efficiently using hydrocarbon or a derivative thereof as a raw material. In order to achieve the above object, the first aspect of the present invention provides a method for producing an oxidation reaction product of a hydrocarbon or a derivative thereof. The method includes the step of irradiating a reaction system with light in the presence of a raw material and a chlorine dioxide radical. The raw material is hydrocarbon or a derivative thereof, the reaction system is a reaction system containing an organic phase, and the organic phase contains the raw material and the chlorine dioxide radical. In the step of irradiating a reaction system with light, the raw material is oxidized by the light irradiation to generate an oxidation reaction product of the raw material.

摘要: The invention relates to the field of petrochemistry, and specifically to a method for synthesizing high-octane oxygen containing components of motor fuel. The objects of the invention consist in variants of a method for synthesizing high-octane oxygen-containing components of motor fuel from olefin-containing gas mixtures via oxidative non-catalytic conversions using nitrous oxide, and the subsequent condensation and hydrogenation of the produced oxygenates using heterogeneous catalysts. The high-octane components according to the proposed method consist in a mixture of carbonyl compounds (ketones, aldehydes, hydroxy ketones, hydroxy aldehydes) C2-C9 and/or branched hydrocarbons C5-C9 and/or alcohols in different ratios. Depending on the production method variant, the octane number of a mixture of the proposed high-octane components consists in a value between 100 and 130 RON. The technical result consists in broadening the resource base for the production of high-octane gasolines and of a variety of environmentally-friendly high-octane additives.
