英文摘要 | CO2加氢被认为是目前固定大量排放CO2的最好方法之一。本文研发出一种碳纳米管(CNT)促进的Cu-ZrO2–HZSM-5沸石分子筛双功能混合型催化剂,将其用于“CO2加氢合成甲醇和甲醇脱水生成DME二步串联催化一器化”,实现由(CO2+H2)直接合成DME。在5.0MPa,523K,V(H2)/V(CO2)/V(N2)=69/23/8,GHSV=25000mL/(h•g)的反应条件下,在所研发(Cu2Zr3-10%CNT)-30%HZSM-5催化剂上,CO2加氢的转化率达9.56%,比相应单功能加氢催化剂(Cu2Zr3-10%CNT)的相应值(7.00%)提高37%。CNT能作为...; In order to improve the climate conditions, it is desirable to develop methods to convert CO2 into valuable chemicals. Here we report the development of a CNT-promoted Cu-ZrO2–HZSM-5 bi-functional hybrid catalyst, which was used for the “one-pot” two-step catalytic synthesis of DME from (CO2+H2) via CH3OH. Over the developed catalyst (Cu2Zr3-10%CNT)-30%HZSM-5 under the reaction conditions of 5.0 M...; 学位:工学硕士; 院系专业:化学化工学院化学工程与生物工程系_工业催化; 学号:20620091151236 |
