ABSTRACT - CTS 9705238 Linda J. Broadbelt Northwestern University A new approach to modeling heterogeneous catalytic reactions and predicting their rates is proposed. Transient techniques of characterization, such as temperature-programmed desorption and reaction (TPD, TPR), yield quantitive information on the energetic heterogeneity of real catalysts. The TPD profiles are reduced to sets of parameters identifying binding energies of chemisorbed species. Those are included in reaction mechanisms, and rates of reaction are thus predicted. This work's goal is to prove the outlined concept by utilizing TPD data from supported and single-crystal nickel catalyst, and verifying predictions against rate data for the methanation of carbon monoxide.

摘要- CTS 9705238琳达J.布罗德贝尔特西北大学 提出了一种新的非均相催化反应模型和速率预测方法。 瞬态表征技术，如程序升温脱附和反应（TPD，TPR），产生真实的催化剂的能量不均匀性的定量信息。 的TPD配置文件减少到一组参数识别化学吸附物种的结合能。 这些都包含在反应机理中，因此可以预测反应速率。 这项工作的目标是证明概述的概念，利用TPD数据从支持和单晶镍催化剂，并验证预测对一氧化碳甲烷化的速率数据。
