    摘要： Disclosed is a process for starting up fluidized reaction apparatus which are used for producing lower olefins from methanol or/and dimethyl ether. Said process includes after heating the catalyst bed of circulating fluidized catalytic reaction apparatus to above 200 °C or 300°C by using a starting-up auxiliary heat source, feeding methanol or dimethyl ether raw materials to a reactor, whereby heat released by the reaction makes the temperature of the reaction system apparatus increase quickly to a designed temperature, consequently making the system reach the normal operation state rapidly. Said process is suitable for starting up an exothermic fluidized catalytic reaction apparatus and can simplify the apparatus and operation, accordingly lowering the cost.

    摘要： This invention relates to a class of microporous metal-silicoaluminophosphate molecular sieves(MeAPSOs) and the method of their fast preparation. These molecular sieves can be represented by the empirical formula on an anhydrous basis: mR· (M q Si x AI y P z )O 2 , wherein "R" represents the templating agent presented in the intracrystalline pore system; " m " is the molar amount of "R" per mole of (M q Si x Al y P z O 2 and has a value from 0.01 to 8.00; "M" represents at least one metal element; " q ", " x ", " y " and " z " represent the molar fractions of metal, silicon, aluminum and phosphorus respectively, whose variations are q=0∼0.98, x=0∼0.98, y=0.01∼0.60, z=0.01∼0.60 and q+x+y+z=1. The crystallization time of the synthesis is 0.5-12 hours, which is defined as the method of fast preparation. This molecular sieve can be used as adsorbents and catalysts of many hydrocarbon conversion processes.

    摘要： The present invention discloses an amine-bromine two electron electrolyte of flow battery and the use thereof, and a flow battery, which belong to the field of flow battery. In the electrolyte, an amino compound with an electron-withdrawing group at the ortho-position of an amino group is used to react with bromine charged to a positive valence so as to form an amine-bromine compound, such that positive-valence bromine is stabilized, and a reversible two-electron transfer reaction from bromine ions to amino compounds is achieved. The amine compounds have different solubilities and produce different voltages depending on their substituent groups, and thus have extensive adjustability and applicability for use in acidic, neutral, and weak alkaline flow battery systems. Flow batteries assembled with the electrolyte prepared using this reaction has the advantages of low cost and high energy density, and can achieve a longer cycle life and higher battery efficiency.

    摘要： The present invention relates to direct preparation of low-carbon olefins by using synthesis gas, and in particular to a catalyst and a method for directly converting synthesis gas into low-carbon olefins. In the method, synthesis gas is used as a reaction raw material and is subjected to a conversion reaction on a fixed bed or a moving bed. The catalyst is a composite catalyst, and is formed by compounding component I and component II in a mechanical mixing manner. The active ingredient of the component I is a metal oxide, and the component II is a molecular sieve having a CHA and AEI structure or one or more of metal modified CHA and/or AEI molecular sieves. The weight ratio between the active ingredient in the component I and component II is in the range of 0.1-20. The reaction process has a very high product yield and selectivity. The sum of selectivity of propylene and butylene reaches 40-75%, the sum of selectivity of low-carbon olefins including ethylene, propylene and butylene can reach 50-90%, and at the same time the selectivity of the byproduct methane is less below 15%, and thus the reaction process has good application prospects.
