【摘要】：通過熱重-紅外-質(zhì)譜(TG-FTIR-MS)三機聯(lián)用技術(shù)對樺甸油頁巖在不同升溫速率的條件下進(jìn)行熱解實驗,計算了其揮發(fā)分氣體析出階段的動力學(xué)參數(shù),并對整個熱解過程中揮發(fā)分氣體的析出特性進(jìn)行了分析,獲得了揮發(fā)分氣體析出的紅外三維譜圖及CH_4、CO_2、CO、H_2O、CnHm和H_2共6種氣體的析出速率隨溫度變化的規(guī)律曲線。其中甲烷作為熱解析出的主要氣態(tài)烴類產(chǎn)物,是多種反應(yīng)綜合作用的結(jié)果,故采用分峰擬合的方法對其在升溫速率為20℃/min下的析出過程進(jìn)行分析。結(jié)果表明,在300~600℃這一溫度區(qū)間,甲烷的生成速率曲線可以分為4個峰,代表了4個反應(yīng)類型,分別計算了其動力學(xué)參數(shù),結(jié)合樺甸油頁巖的結(jié)構(gòu)特性及熱解過程中其他氣體析出的特性,分析了各個反應(yīng)甲烷的生成機理。
[Abstract]:The pyrolysis experiments of Huadian oil shale at different heating rates were carried out by means of TG-FTIR-MS3 combined with thermogravimetric infrared mass spectrometry (TG-FTIR-MS), and the kinetic parameters of the volatile gas precipitation stage were calculated. The precipitation characteristics of volatile gases in the whole pyrolysis process were analyzed. The infrared three-dimensional spectra of volatile gases and the curves of the precipitation rates of six gases, CH4CO2CO2CnHm and H2CnHm, as well as the temperature variation of CH4CO2CO2CnHm and H2 were obtained. Methane, as the main gaseous hydrocarbon product, is the result of various reactions. Therefore, the precipitation process of methane at 20 鈩，
