The objectives of this research are to experimentally identify the effects of pore size on reaction rate in systems where the molecular size of the reacting species is comparable to that of the pore sizes within the material where the reaction is taking place. Based on the hypothesis that pore size influences the intrinsic reaction rate of large molecules within porous materials, a research program will be estalbished to investigate the effect in model reaction systems representative of the processing and upgrading of petroleum feedstocks as well as those of importance in the biotechnology field. The goal of the research is to address questions such as: Does the effect exist? What differences are observed between various reaction systems, for example, immobilized enzyme reactions versus catalytic hydrogenation reactions? What experimental techniques are needed to study the effect unambiguously? What is the functional dependence of the rate constants on the ratio of molecular diameter to pore diameter?

本研究的目的是通过实验确定孔径对反应速率的影响，在反应物质的分子大小与反应发生的材料的孔径大小相当的系统中。基于孔隙大小影响多孔材料中大分子的本征反应速率的假设，将建立一个研究项目，研究具有代表性的石油原料加工和升级的模型反应系统以及生物技术领域的重要反应系统的影响。这项研究的目的是解决以下问题：这种效应存在吗？在不同的反应体系之间观察到什么差异，例如，固定化酶反应与催化氢化反应？需要什么样的实验技术来明确地研究这种效应？速率常数对分子直径与孔径之比的函数依赖性是什么？
