O2 or CuOx. Oxidation of methoxide species to HCHO was found to be the rate-controlling step in oxidation of CH3OH to formate species, and HCHO was identified as the reaction intermediate in the synthesis of dimethoxy methane (DMM) and methyl formate (MF), the two major by products in dimethyl carbonate (DMC) synthesis.KEY WORDS：Cu-zeolite, CO adsorption, oxidative carbonylation, DRIFTS目录第一章 文献综述..........................................................................................................11.1 引言 ...........................................................................................................11.2 分子筛简介及工业应用 ...........................................................................11.3 Cu-分子筛催化剂中 Cu 活性位的表征21.3.1 SAPO-34 分子筛21.3.2 Cu-SAPO-34 催化剂中 Cu 活性位的表征21.3.3 Y 型分子筛31.3.4 CuY 催化剂中 Cu 活性位的表征41.4 Cu-分子筛催化剂在氧化羰基反应中的应用81.4.1 DMC 简介81.4.2 氧化羰基化法合成 DMC81.4.3 氧化羰基合成 DMC 反应机理的研究 101.5 论文工作的提出 .....................................................................................12第二章 实验部分........................................................................................................142.1 化学试剂 .................................................................................................142.2 催化剂的制备 .........................................................................................152.2.1 Cu-SAPO-34 催化剂的制备 152.2.1.1 焙烧-活化法制备 Cu-SAPO-34 催化剂 152.2.1.2 高温固体离子交换法制备 Cu-SAPO-34 催化剂 152.2.1.3 液体离子交换法制备 Cu-SAPO-34 催化剂 152.2.2 HY 分子筛的制备 152.2.3 CuCl 提纯 162.2.4 CuY 分子筛催化剂的制备 162.2.5 催化剂性能评价装置与方法.......................................................162.2.6 催化剂表征...................................................................................172.2.6.1 吡啶吸附红外表征.....................................................................172.2.6.2 漫反射原位红外表征.................................................................182.2.6.3 质谱分析.....................................................................................182.2.6.4 等离子体发射光谱(ICP-OES) 19第三
