摘要
本文以工业应用为目的，采用内循环无梯度反应器，在５７３～６７３Ｋ，０．３０～１．２０ＭＰａ的条件下，原料气组成为Ｈ＿２５０～５４％，ＣＯ１１．７～２０．７％，ＣＨ＿４２．１～１４．３％，ＣＯ＿２６．４～１１．５％，Ｎ＿２１２．２～１８．１％范围内，研究了φ５×３ｍｍＳＤＭ－１型城市煤气耐硫甲烷化催化剂的宏观动力学方程。选择ＣＯ＋３Ｈ＿２＝ＣＨ＿４＋Ｈ＿２Ｏ（１）ＣＯ＋Ｈ＿２Ｏ＝ＣＯ＿２＋Ｈ＿２（２）为系统的独立反应，获得了可靠的动力学模型，井讨论了反应条件对甲烷化反应效率因子的影响。
The macrokinetics of methanation over φ5×3mm sulfur-tolerant SDM-1catalyst was studied in a gradientless reactor with internal-recycle under conditions 300～400℃,0.30～1.20MPa,H_2 50～54%,CO 11.7～20.7%,CH_4 2.1～14.3%, CO_2 6.4～11. 5%and N_2 12.2～18.1%. The two independent reactions in this work were chosen as fol-lows:CO+3H_2=CH_4+H_2O CO+H_2O=CO_2+H_2 Reasonable globalkinetics has been derived from the two reactions.The influence of re-action conditions on the effectiveness factor of metbanation is also discussed.
