【摘要】：為了驗證吸附強化焦?fàn)t荒煤氣重整制氫工藝的可行性,并為相關(guān)的實驗研究提供理論依據(jù),文章采用HSC Chemistry軟件對焦?fàn)t荒煤氣全組分蒸汽重整反應(yīng)進行熱力學(xué)分析,研究反應(yīng)溫度、反應(yīng)壓力、S/C,CaO/C對H_2產(chǎn)率、濃度等的影響。研究結(jié)果表明:焦?fàn)t荒煤氣蒸汽重整反應(yīng)能夠有效地脫除焦油組分,隨著S/C的增大,H_2產(chǎn)率會得到明顯提升,且最佳H2產(chǎn)率所對應(yīng)的反應(yīng)溫度會隨之降低,當(dāng)S/C為5∶1,反應(yīng)溫度為700℃時,H_2產(chǎn)率為1.62 mol/mol,但H_2濃度僅為75%左右;CO_2吸附劑的加入會強化蒸汽重整反應(yīng),H_2產(chǎn)率、濃度均會顯著提升,最佳重整反應(yīng)區(qū)的反應(yīng)溫度會隨之降低,當(dāng)反應(yīng)溫度為500~600℃,S/C為5∶1,CaO/C為3∶1時,H2產(chǎn)率、濃度能夠分別達到1.83 mol/mol,98%以上。
[Abstract]:In order to verify the feasibility of adsorption enhanced reforming of coke oven gas for hydrogen production and to provide theoretical basis for related experimental research, the thermodynamic analysis of steam reforming reaction of coke oven waste gas is carried out by using HSC Chemistry software. The effects of reaction temperature, reaction pressure and S / C / Cao / C on the yield and concentration of H _ 2 were studied. The results show that the steam reforming reaction of coke oven waste gas can effectively remove the tar component. With the increase of S / C, the yield of H _ 2 will be obviously increased, and the reaction temperature corresponding to the optimum H _ 2 yield will decrease. When S / C is 5: 1 and the reaction temperature is 700 鈩，
