Analysis of Sequential Reactions Using Isotopic Transient Kinetics

Goodwin教授将继续通过稳态范围同位素瞬态动力学分析（SSITKA）技术研究催化机制。 在这项研究中，他打算将SSITKA技术扩展到顺序反应，特别是在双功能催化剂上将CO加氢为甲醇和二甲醚，包括负载在二氧化硅，氧化铝，HY沸石，二氧化硅-氧化铝和二氧化硅-HY沸石上的Pd。 活性中间体的表面浓度、特定位点活性、位点异质性、产物的再吸附，将被区分为每种类型的位点，即金属位点和酸性位点。 矩分析，线性卷积，去卷积方法将被用来分析从所描述的反应获得的同位素瞬态动力学数据。SSITKA计划将免费分发。

Prof. Goodwin will continue his research on the study of catalytic mechanisms by means of the Steady Scope Isotopic Transient Kinetic Analysis (SSITKA) technique. In this research he intends to extend the SSITKA technique to sequential reactions, particularly to the hydrogenation of CO into methanol and dimethyl ether on bifunctional catalysts, including Pd supported on silica, alumina, HY zeolite, silica-alumina, and silica-HY zeolite. Surface concentration of reactive intermediates, specific site activity, site heterogeneity, readsorption of product, will be discriminated for each type of site, namely metallic and acidic sites. Moment analysis, linear convolution, and deconvolution methods will be used to analyze the isotopic transient kinetic data obtained from the described reaction. The SSITKA program will be distributed freely.
