【摘要】：為了準(zhǔn)確預(yù)測(cè)低溫條件下煤對(duì)甲烷的吸附等溫線,選用平頂山己15-17煤層煤樣,并以高低溫變頻實(shí)驗(yàn)裝置為依托,對(duì)煤樣進(jìn)行高/低溫環(huán)境(-20、-10、0、10、20℃)下的甲烷吸附試驗(yàn)。基于吸附勢(shì)理論,利用吸附特性曲線的唯一性,根據(jù)20、10、0℃的甲烷吸附數(shù)據(jù),預(yù)測(cè)-10、-20℃時(shí)甲烷的吸附等溫線。結(jié)果表明:預(yù)測(cè)的吸附等溫線與實(shí)測(cè)的吸附等溫線吻合良好,平均相對(duì)誤差分別為2.47%和2.64%。
[Abstract]:In order to accurately predict the adsorption isotherm of methane to coal under low temperature condition, coal samples from Pingdingshanji 15-17 coal seam were selected, and the methane adsorption experiments were carried out under high / low temperature environment (-20 ~ 10 ~ (10) ~ (10) ~ (10) ~ (20 鈩，
