不同煤级煤对H2S气体的吸附差异及吸附模型
Adsorption and adsorption model of H2S in different coal ranks
摘要
Abstract
In order to research H2S adsorption and adsorption model in different ranks coal, the proximate analysis, petrography analysis and isotherms adsorption experiment were conducted respectively on Xinjiang gas coal, Lu'an lean coal and Jincheng anthracite. Langmuir, BET, D-R and D-A models were adopted, fitting software was used to conduct nonlinear regression fitting of data of isothermal adsorption experiment and examine the fitting degree. The results showed that H2S adsorption increased with coal rank, and was of sorption isotherm type I. The fitting results of Langmuir model were the best, followed by D-A model, BET model was poor. The fitting degree had nothing to do with the number of parameters. The theory of monolayer adsorption can be used to explain H2S adsorption in coal.关键词
