The kinetics of methane steam catalytic reforming reaction over Z 102 nickel catalyst had been investigated in internal recycle gradientless reactor at atmospheric pressure. Experimental conditions were as follows:reaction temperature range 500-700℃, H2O/CH4=2.5-4.5 (molar ratio), methane space velocities 2000-10000ml/h.g-cat. According to the analysis of experimental results the authors have considered that carbon monoxide and carbon dioxide are formed together in these reaction process, i. e, catalytic steam...

在常压下使用内循环式无梯度反应器研究了Z102镍催化剂上甲烷水蒸汽催化转化反应的动力学。实验条件如下:反应温度500—700℃,H_2O/CH_4=2.5—4.5(克分子比),甲烷空速为2000—10000ml/h·g-cat。根据实验结果的分析,作者认为在反应过程中一氧化碳和二氧化碳是同时生成的,即甲烷水蒸汽催化转化反应可用平行反应模型来表示。所得到的一氧化碳及二氧化碳的生成速度方程分别为: rco=k,p_(CH_4)~(0.8)及 rco_2=k_2p_(CH_4)~(0.8) p_(H_2O)~(1.5)反应速度常数k_1及k_2与温度的关系均符合阿累尼乌斯方程。一些研究者认为在通常的操作条件下,甲烷水蒸汽催化转化反应过程中,水煤气变换反应很快就达到平衡,我们的实验数据计算证明这个见解是不妥的。

In comparison with potassium carbonate catalyst, the activies of sodium carbonatecalcium oxide compound catalysts in steam gasification of Jinggezhuang gas coal under normal pressure and the effects of potassium sulfate or ferrous sulfate additives have been investigated. A better blending ratio of sodium carbonate to calcium oxide was obtained and the influence of temperatures on activity of this type of catalysts was investigated. It is fo(?)d that 5% sodiun carbonate—10% calcium oxide compound catalyst behaves a higher activity in steam gasification of Jinggezhuang coal. In addition, the influences of tenperatures, pressures and rates of steam supply on steam catalyeic gasification of Jinggezhuang coal with a sodium—calcium compound catalyst under pressurized conditions were studied and discussed. It is odserved that the above-mentioned catalyst is more active in pressurized gasification, bat less active in methanation.

The reaction of methane, carbon dioxide and steam over a nickel-work catalyst has been studied in integral flow reactor at 1.1 atm and high temperature. Conversion data at 1100℃, CO2/CH4 = 0.9 and CO2/H.2O=1.45 (molar ratio) were collected. These data are fitted with an exponential-second polynomial spline function. According to the experimental results it was concluded that the following two primary reactions were CH4+H2O=CO+3H2 and CO2+H2=H2O+CO. Considering the influence of interior diffusion, a kinetic model is proposed:The computer simulation showed that the model was reasonable, the mean deviations of calculated and experimental values were no more than 2%. The calculation of experimental data indicated that water gas shift reaction was not at equilibrium. The experiment shows that the hole diameter, hole number and activity of catalyst in the catalysis bed of reformer is approriate.
