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.

古德温教授将继续利用稳定范围的同位素瞬时动力学分析(SSITKA)技术研究催化机理。在这项研究中，他打算将SSITKA技术扩展到连续反应，特别是CO在双功能催化剂上的加氢合成甲醇和二甲醚，包括二氧化硅、氧化铝、HY沸石、硅-氧化铝和硅-HY沸石负载的钯。活性中间体的表面浓度、特定的中心活性、中心的异质性、产物的再吸附将被区分为每种类型的中心，即金属中心和酸性中心。将使用矩分析、线性卷积和反卷积方法来分析从所述反应中获得的同位素瞬时动力学数据。SSITKA程序将免费分发。
