Abstract: A titanium silicalite molecular sieve has a micropore specific surface area of 320-500 m2/g, a micropore volume of 0.1-0.4 cm3/g, a mesopore specific surface area of 50-100 m2/g, a mesopore volume of 0.075-0.1 cm3/g, and a particle size of 100-250 nm. Its micropore specific surface area accounts for 50-90% of the total specific surface area. A catalyst contains the titanium silicalite molecular sieve carrier and is loaded with nano-gold particles. The catalyst has a micropore volume of 0.06-0.4 cm3/g and a particle size of 100-250 nm. The catalyst is prepared by subjecting the titanium silicalite molecular sieve to an alkaline treatment with an aqueous aliphatic amine solution and then loading same with nano-gold particles. The catalyst is used for an olefin epoxidation reaction, a cycloolefin epoxidation reaction, a phenol hydroxylation reaction, and a cyclohexanone ammoximation reaction.

Abstract: 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 CO2 is generated; the ignition and explosion risk is avoided; and the reactor is safer and more environmentally friendly.

Abstract: A gas sensor has a sensing structure that is used for generating, for a variety of gases, multiple corresponding electric signals. It has a plurality of measuring electrodes and a gas-sensitive film coating the measuring electrodes; and a micro-heating structure that is used for providing different heating temperatures for the sensing structure, and a silicon-based substrate and a heating layer disposed on the silicon-based substrate. The heating layer integrates heating electrodes of different sizes or different layouts to form a plurality of heating regions of different temperatures, and the plurality of measuring electrodes are respectively disposed in the corresponding heating regions. By integrating heating electrodes of different sizes or different layouts on a single micro-heating structure to form heating regions of different temperatures, a complex atmosphere detection function of a variety of sensing materials at different temperatures is achieved.

Abstract: A method of preparing epoxypropane by direct epoxidation of propylene includes the steps of contacting a mixed gas consisting of a reaction feed gas and a diluent gas with a catalyst to carry out reaction under reaction conditions of propylene epoxidation to prepare epoxypropane. The reaction feed gas contains propylene, oxygen gas and hydrogen gas while at least a portion of the diluent gas is a gaseous olefin. Using gaseous olefin as at least a portion of the diluent gas to perform propylene epoxidation that can significantly extend service life of the catalyst, effectively reduce the used amount of diluent gas, and improve the reaction selectivity and propylene conversion rate.

Abstract: A method and system for preparing epoxypropane by direct epoxidation of propylene includes the steps of 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. 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 contains a diluent gas. The method 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.
