Reversible reactions (A + B = C + D) can be performed to near completion using an admixture of catalyst and sorbent that will selectively adsorb one of the reaction products. For an initially clean sorbent and a favorable adsorption isotherm and a long reactor, the adsorbed product, C, will propagate as a sharp, shock-like front. While the adsorbed product will not move faster than this front, the second, nonadsorbed product, D, will, in principle, leave the reactor, uncontaminated. However, a parametric analysis of the two examples presented in this work, the water gas shift and the cracking of hydrogen sulfide, reveals an unexpectedly complex behavior. While assuming adsorption equilibrium the effect of the equilibrium constant, the reaction kinetics and adsorption isotherm on the reactant and product concentration profiles are simulated. It is found that desired behavior is favored by large equilibrium constants, rapid kinetics, and strong nonlinear adsorption. © 2017 American Institute of Chemical Engineers AIChE J, 2017

吸附增强了可逆反应中高纯度产品的反应

可以使用催化剂和吸附剂的混合物进行可逆反应（A + B = C + D）接近完成，该混合物将选择性地吸附一种反应产物。对于最初清洁的吸附剂和有利的吸附等温线，以及较长的反应器，被吸附的产物C将以锋利的，像冲击一样的锋面传播。虽然被吸附的产品移动的速度不会比此前沿快，但第二个未吸附的产品D原则上不会污染反应器。但是，对本工作中出现的两个示例（水煤气变换和硫化氢裂解）的参数分析显示出意想不到的复杂行为。在假定吸附平衡的情况下，模拟了平衡常数，反应动力学和吸附等温线对反应物和产物浓度分布的影响。发现理想的行为受到较大的平衡常数，快速动力学和强非线性吸附的影响。©2017美国化学工程师学会AIChE的Ĵ，2017年
