项目摘要

The catalysis which proceeds under a mild condition is one of the biggest targets of research work since the energy saving in chemical processes is great concern from the view point of environmental protection. This work aimed at clarifying adsorption interactions between adsorbates and catalyst materials, providing some useful information for development of carbon monoxide hydrogenation catalyst at mild conditions, such as modified Raney nickel.1. IR spectroscopic analysis of adsorbatesIR spectroscopic analysis of adsorbate was selected as the major procedure, and a laboratory made defuse reflectance IR cell was developed and tested under a wide range of temperature and pressure conditions. Catalyst and catalyst support materials, such as zeolites, mesoporous silicates, and activated carbons, were analyzed by molecular prove procedure.2. The effect of preparation condition of Raney nickel catalyst on the catalytic activity of CO hydrogenationIt was found that the selectivity of a nickel catalyst, which is the most typical methanation catalyst of CO, can be varied by some additives because of the change in adsorption selectivity. Similar effects were also proved in the change in catalyst development conditions.

在温和条件下进行的催化是研究工作的最大目标之一，因为从环境保护的角度来看，化学过程中的节能受到高度关注。本工作旨在阐明吸附质与催化剂材料之间的吸附相互作用，为开发温和条件下的一氧化碳加氢催化剂（例如改性雷尼镍）提供一些有用的信息。 1．吸附物的红外光谱分析选择吸附物的红外光谱分析作为主要程序，开发了实验室自制的漫反射红外池，并在广泛的温度和压力条件下进行了测试。采用分子证明程序对催化剂和催化剂载体材料，如沸石、介孔硅酸盐和活性炭进行了分析。 2．雷尼镍催化剂的制备条件对CO加氢催化活性的影响研究发现，作为最典型的CO甲烷化催化剂的镍催化剂，由于吸附选择性的变化，可以通过添加一些添加剂来改变其选择性。催化剂开发条件的改变也证明了类似的效果。
