    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 application discloses a method for preparing glycolic acid and methyl glycolate through hydrolysis of methyl methoxyacetate and methoxyacetic acid. The method includes: allowing raw materials including methyl methoxyacetate, methoxyacetic acid, and water to contact and react with a catalyst to produce glycolic acid and methyl glycolate, where the catalyst is at least one selected from the group consisting of a solid acid catalyst, a liquid acid catalyst, a solid base catalyst, and a liquid base catalyst. The method for preparing glycolic acid and methyl glycolate in the present application can be implemented by a traditional fixed-bed reactor, tank reactor, or catalytic distillation reactor under an atmospheric pressure, which is very suitable for continuous production. When used in combination with methanol and formaldehyde condensation to prepare dimethoxymethane (DMM) and DMM carbonylation to prepare methyl methoxyacetate, the method in the present application can allow efficient, environmentally-friendly, and economical conversion of methanol (a platform chemical in the coal chemical industry) into glycolic acid and methyl glycolate.

    摘要: Disclosed are a catalyst and a method for preparing low aromatic hydrocarbon liquid fuel by direct conversion of synthesis gas. According to the method, synthesis gas is used as a raw material of reaction and is subject to conversion reaction on a stationary bed or a moving bed; the catalyst is a composite catalyst by mechanically mixing component I and component II, the active ingredients in component I being metal oxides, component II including one or more than two molecular sieves having one-dimensional ten-membered ring pore passage, and a weight ratio of the active ingredients in component I to the active ingredients in component II being within a range of 0.1-20 times. The reaction process has high product yield and selectivity; the liquid fuel composed of C 5 -C 11 has a selectivity up to 50-80%; the aromatic hydrocarbon in C 5 -C 11 has a selectivity lower than 40%, and side product methane has a selectivity lower than 15%; therefore, the method has good application prospect.
