【摘要】：選取中國(guó)樺甸、撫順、窯街3個(gè)地區(qū)油頁(yè)巖,酸洗得到各干酪根樣品。應(yīng)用TG-FTIR技術(shù)對(duì)不同升溫速率下各干酪根與蒙脫石共熱解行為進(jìn)行了研究,并利用Coats-Redfem積分法對(duì)升溫速率為10℃/min下的干酪根摻混樣品進(jìn)行熱解反應(yīng)動(dòng)力學(xué)分析,獲得了蒙脫石對(duì)干酪根熱解產(chǎn)物析出規(guī)律的影響及熱解過程的活化能(E)和指前因子(A)。結(jié)果表明,隨著蒙脫石摻混比例增大,樺甸和撫順干酪根熱解失重率先升高后降低;在熱解過程中,440℃前干酪根與蒙脫石摻混樣品的熱解失重率較干酪根單獨(dú)熱解低,而440℃后其熱解失重率較干酪根熱解有所提高;蒙脫石摻混比例增大使得各干酪根熱解產(chǎn)物中CH_3/CH_2值有所增加;有蒙脫石摻混的干酪根熱解活化能相比干酪根熱解活化能有所降低。表明蒙脫石對(duì)油頁(yè)巖干酪根熱解具有物理吸附和裂解催化兩種作用,且隨著熱解過程的加深和蒙脫石配比的改變而不同。最后,對(duì)升溫速率為10℃/min的樣品進(jìn)行了熱解反應(yīng)動(dòng)力學(xué)分析,進(jìn)一步探討了蒙脫石對(duì)干酪根的熱解影響機(jī)理。
[Abstract]:Oil shale was selected from Huadian, Fushun and Yaojie, China, and samples of kerogen were obtained by acid washing. The co-pyrolysis behavior of kerogen and montmorillonite at different heating rates was studied by TG-FTIR technique. The pyrolysis kinetics of kerogen mixed samples at 10 鈩，
