A non-linear dynamic analysis model which is suitable for methanation oncommercial Ni-Al catalyst is derived.The adsorption rate and equilibrium constants of re-versibly adsorbed hydrogen and carbon monoxide were obtained by using the non-linear dy-namic analysis model and Modified-powell method.The results showed that the adsorptionof reversible hydrogen is 2.2 times faster than that of reversible carbon monoxide, Becausethe reversible adsorption hydrogen and irreversible carbon monoxide are...

A non-linear dynamic analysis model which is suitable for methanation oncommercial Ni-Al catalyst is derived.The adsorption rate and equilibrium constants of re-versibly adsorbed hydrogen and carbon monoxide were obtained by using the non-linear dy-namic analysis model and Modified-powell method.The results showed that the adsorptionof reversible hydrogen is 2.2 times faster than that of reversible carbon monoxide, Becausethe reversible adsorption hydrogen and irreversible carbon monoxide are responsible for theformation of methane,the adsorption of irreversible carbon monoxide is far slower than thatof reversible carbon monoxide and the concentration of irreversible carbon monoxide does notvary with pressure. Thus,elevating pressure have no effect on the mathanation,that is,themethanation should be performed at atmosphere pressure.

在推导出适应于甲烷化反应体系非线性动态分析不同吸附物种动力学参数模型的基础上,采用计算机优化出工业镍铝甲烷比催化剂上可逆吸附氢和可逆吸附一氧比碳的吸附速率常数和吸附平衡常数。结果表明,镍铝催化剂上吸附可逆氢要比吸附一氧化碳快2.2倍左右。该结果为镍铝催化剂上甲烷化产物的生成主要依赖于一氧化碳的吸附这一判断提供了理论依据。由于镍铝催化剂上甲烷化是可逆吸附氢与不可逆吸附一氧化碳共同作用的结果,且不可逆吸附一氧化碳不随压力而变化,因而镍铝催化剂上的甲烷化反应可在常压下进行。

The 6 # extraction solvent oil contains benzene 12.28, toluene 3.32, and total aromatic hydrocarbons 15.60%. Hydrodearomatization of the feed was carried out on a 10 ml scale fixed bed microreactor chromatography unit over a Ni Al catalyst. Effects of reaction conditions on the dearomatization were investigated. The preferred results were obtained at reaction condition of 130 ℃, 0 5 MPa,SV=1 0 h -1 and H 2/oil volumeric ratio of 70∶1. At this condition, the hydrogenated oil contains less than 0...

The 6 # extraction solvent oil contains benzene 12.28, toluene 3.32, and total aromatic hydrocarbons 15.60%. Hydrodearomatization of the feed was carried out on a 10 ml scale fixed bed microreactor chromatography unit over a Ni Al catalyst. Effects of reaction conditions on the dearomatization were investigated. The preferred results were obtained at reaction condition of 130 ℃, 0 5 MPa,SV=1 0 h -1 and H 2/oil volumeric ratio of 70∶1. At this condition, the hydrogenated oil contains less than 0 05% aromatic hydrocarbons,which meets the requirment of 6 #extraction solvent oil for aromatic hydrocarbons content of less than 0 1%.
