摘要： A method for reducing the risk of burning and explosion in a deoxygenation process of an oxygen-containing gas. The method comprises: in the presence of a gaseous alkane, mixing an oxygen-containing gas from which an unsaturated hydrocarbon is removed with hydrogen, so that oxygen in the oxygen-containing gas undergoes an oxidation reaction with the hydrogen, wherein the oxygen-containing gas contains the oxygen and the unsaturated hydrocarbon, and the content of the oxygen in the oxygen-containing gas is greater than 0.5% by volume. A gaseous alkane is introduced to reduce the risk of burning and explosion of a mixed gas; a hydrocatalytic reaction is carried out to promote oxygen in the mixed gas to react with hydrogen to produce water, such that the purpose of deoxygenation of an oxygen-containing gas is achieved and the reaction product is clean; and the hydrocatalytic reaction can effectively inhibit the occurrence of carbon deposition on the surface of a catalyst and the production of a carbon oxide, and a strong endurance for fluctuation of the oxygen content in a raw gas is provided.

摘要： The present disclosure relates to the technical field of the preparation of epoxypropane, and particularly to a method and system for preparing epoxypropane by direct epoxidation of propylene. The method comprises: subjecting a mixed gas of a first feed gas and a second feed gas to a contact reaction with a catalyst under reaction conditions of propylene epoxidation to prepare epoxypropane, wherein the first feed gas contains oxygen gas and is free or substantially free of hydrogen gas, the second feed gas contains hydrogen gas and is free or substantially free of oxygen gas, the first feed gas and/or the second feed gas contain propylene, at least one of the first feed gas and the second feed gas further comprises a diluent gas. The technical solution of the disclosure can be used for reducing dosage of diluent gas, preferably recycling the tail gas, thereby significantly increasing the conversion rate of propylene without compromising the service life of catalyst.

摘要： The present invention relates to the field of energy chemical industry, and disclosed are a gliding arc plasma reactor, and a method for converting methane by means of plasma. The reactor comprises a reactor chamber and a gliding arc plasma generator arranged in the reactor chamber, wherein the gliding arc plasma generator comprises at least two arc surface electrodes which are symmetrically distributed, such that a discharge area can be formed between the arc surface electrodes. According to the gliding arc plasma reactor provided in the present invention, the conversion rate of methane can be significantly improved when methane is converted into olefin; the selectivity of ethylene in the product is improved; and carbon deposition is significantly reduced. In addition, compared with a traditional process for preparing olefin from methane, no CO 2 is generated; the ignition and explosion risk is avoided; and the reactor is safer and more environmentally friendly.

摘要： Provided a catalyst, and a catalytic oxidation-deoxidation method for an unsaturated hydrocarbon-containing gas using the catalyst. The catalyst comprises a carrier as well as an active component, a first co-agent component, and a second co-agent component loaded on the carrier respectively, wherein the active component is one or more selected from the group consisting of oxides of Pt, Pd, Ru, Rh, Ag and Ir; the first co-agent component comprises one or more selected from the group consisting of a rare earth metal element, a group IVB metal element and a group VIII metal element; and the second co-agent component comprises one or more selected from the group consisting of an alkali metal element and an alkaline earth metal element. The deoxidation method using the catalyst obviates the need to add a reducing gas such as H 2 , allows hydrocarbons to react directly with oxygen to produce CO 2 and H 2 O, achieves the goal of deoxidating a hydrocarbon-containing tail gas, and can prevent the generation of carbon deposits.
