摘要
采用波长为253.7 nm的紫外光为光源,以Na2S溶液为反应液,进行了紫外光液相光化学法分解硫化氢(H2S)制氢反应。考察了S的存在形式、Na2S溶液的浓度、Na2SO3溶液浓度及H2S通入流量对制氢的影响。研究结果表明,溶液中S以HS-的形式存在有利于紫外光的分解;加入Na2SO3可以提高体系的产氢量;在体系中通入H2S可以使产氢速率保持稳定。
Decomposition of H2S to produce H2 was carried out under ultraviolet light with the characteristic wavelength of 253.7nm in Na2S solution. The effects of the existing form of sulfur, the concentration of Na2S and Na2SO3, and the successive feed rate of H2S on the production of H2 were studied. The result showed that S existed with HS-was beneficial to decomposition of H2S to produce H2, Na2SO3 could increase the H2 yield, and the addition of H2S could keep the rate of H2 production stable.
