ABSTRACT A dry reforming (DR) catalyst based on bimetallic Pd–Pt supported on carbon nanotubes is presented. The catalyst was prepared using a microwave-induced synthesis. It showed enhanced DR activity in the 773–923 K temperature range at 3 atm. Observed carbon balances between the reactant and product gases imply minimal carbon deposition. A global three-reaction (reversible) kinetic model—consisting of DR, reverse water gas shift, and CH4 decomposition (MD)—adequately simulates the observed concentrations, product H2/CO ratios, and reactant conversions. Analysis shows that, under the conditions of this study, the DR and MD reactions are net forward and far from equilibrium, while the RWGS is near equilibrium.

碳纳米管催化剂钯铂上甲烷干法重整

摘要介绍了一种基于双金属 Pd-Pt 负载在碳纳米管上的干重整 (DR) 催化剂。使用微波诱导合成制备催化剂。它在 3 个大气压的 773-923 K 温度范围内显示出增强的 DR 活性。观察到的反应物和产物气体之间的碳平衡意味着最小的碳沉积。由 DR、反向水煤气变换和 CH4 分解 (MD) 组成的全局三反应（可逆）动力学模型充分模拟了观察到的浓度、产物 H2/CO 比率和反应物转化率。分析表明，在本研究条件下，DR和MD反应为净正向且远离平衡，而RWGS接近平衡。
