摘要: A method for preparing p-xylene is provided. Raw materials containing methanol, naphtha and CO2 are introduced into a reactor filled with a catalyst for a reaction to produce p-xylene. By adding the methanol, the product distribution is adjusted, and the selectivity of p-xylene is obviously improved. In addition, components containing benzene and toluene in aromatic hydrocarbon products are returned to a reaction system and co-fed with the raw materials for a reaction to produce p-xylene, so that cyclic utilization of the raw materials is achieved, and the method has extremely high economic benefits. The method has a simple process and high feasibility, can greatly improve the selectivity and yield of p-xylene, has an important application value, and provides a new way for large-scale utilization of CO2.

摘要: Disclosed is a method for partially regenerating a catalyst for methanol and/or dimethyl ether-to-olefin. The method comprises: introducing a mixed gas into a regenerated region containing a catalyst to be regenerated, and subjecting same to a partial regeneration reaction to obtain a regenerated catalyst, wherein the mixed gas contains water vapor and air; and in the regenerated catalyst, the coke content of at least part of the regenerated catalyst is greater than 1%. The method utilizes the coupling of a mixed gas of water vapor and air to activate a deactivated catalyst, selectively eliminate part of a coke deposit in the catalyst to be regenerated, and obtain a partially regenerated catalyst for methanol-to-olefin. Another aspect of the present invention is that further provided is a method for methanol and/or dimethyl ether-to-olefin by using the partially regenerated catalyst for methanol-to-olefin regenerated by means of the method.

摘要: A burner includes a housing, a fan, a burning head and an ignition mechanism. An air inlet of the housing and an input end of the burning head form a pressure equalizing cavity. The ignition mechanism is arranged at an output end of the burning head. The burning head includes a main frame and at least one stable burning isolation strip, an interior of the main frame is divided into at least two ventilation areas by the stable burning isolation strip in a gas channel direction. A plurality of separation mechanisms is arranged in each ventilation area and divide the ventilation area into a plurality of through holes arranged in the gas channel direction, the through holes are used for allowing mixed gas to pass through and strengthening the mixing effect. The burning flame of a burning surface of the main frame can be divided into mutually independent flames by the stable burning isolation strip. The burner can be used in gas stoves, low-nitrogen combustion engines for a gas boiler, gas water heaters and gas heating water heaters.

摘要: A method of solvent-induced protein precipitation (SIP) for detecting the interaction of ligands with proteins in a complex protein sample. After the equal amount of solvent is added to the protein samples with and without a ligand to denature and precipitate the proteins, the protein abundances in supernatant and/or precipitate in the ligand group and the control group are measured by quantitative technology. The target protein(s) of a ligand is/are determined by comparing the differences of protein abundances in the ligand group and the control group. The affinity between a ligand and its targets can be evaluated by dose dependent experiments. This method does not require the chemical modification of the ligand and has the feature of high specificity. Furthermore, in certain embodiments, the targets identified by SIP method are complementary to those identified by thermal proteome profiling (TPP) method.
