    摘要： An organic base modified composite catalyst and a method for preparing ethylene by means of hydrogenation by carbon monoxide. Mixed gas of carbon monoxide and hydrogen is used as a reaction raw material to carry out a conversion reaction on a fixed bed or a moving bed. The catalyst is a composite catalyst prepared by combining component I and component II together in a mechanical mixing manner; The active ingredient of component I is a metal oxide, and component II is a molecular sieve with an organic base modified MOR structure; and the organic base is aliphatic amine. The reaction process has high product yield and selectivity; the C 2 -C 3 olefin selectivity is as high as 78-87%, wherein the selectivity of hydrocarbon products containing four or more C atoms is less than 10%; the selectivity of byproduct methane is extremely low (

    摘要： The invention relates to zinc iodine flow batteries, including zinc iodine single flow batteries or zinc iodine dual-flow batteries, which includes single batteries or cell stacks assembled with two or more single batteries connected in series. The single flow battery includes a positive end plate, a positive current collector, a negative current collector, a positive electrode with a flow frame, a membrane, a negative electrode with a flow frame, a negative end plate. The negative electrolyte is circulated between the negative storage tank and the negative cavity by pump. In addition, the negative pipe is provided with a branch pipe for the positive electrolyte circulation. The porous membrane between the positive and negative electrodes can realize the conduction of supporting electrolyte and prevent the diffusion of I 3 - to the negative electrolyte. Due to the high solubility of active substance in the electrolyte, the flow battery achieves a high energy density so it is suitable for constructing single flow battery. In a duel-flow battery system, same electrolyte serves as both the positive electrolyte and the negative electrolyte, which is a mixed aqueous solution containing iodized and zinc salt. The membrane is porous membrane without ion exchange group. At the same time, both the positive and negative electrolyte are neutral solutions, which avoids the corrosion problem of traditional flow battery using strong acid and alkali electrolyte. At the same time, the battery obtains high current density, long cycle life and low cost.
