Synergistic effect of nitrogen-doped carbon-nanotubes-supported Cu–Fe catalyst for the synthesis of higher alcohols from syngas

Abstract

合成气(H2+CO)可从煤炭、天然气、页岩气、生物质乃至有机垃圾等含碳物质中制取,是C1化学的起始原料和中间产物,在化学工业中具有极为重要的地位。由于低碳醇不仅可作为高附加值化工原料,而且还可以作为替代燃料和油品添加剂,因此,转化合成气制取低碳醇(C2+-OH)是C1化学中的重要课题之一。 过去几十年来,为提高CO转化率和醇的收率,人们在催化剂设计、制备、组成和结构等方面积累了许多有意义的经验和见解,但仍然存在不少科学问题亟待解决,其中最为突出的问题包括:催化剂对低碳醇的选择性和产率较低,容易烧结失活。大量的研究工作表明,采用具有合适酸碱性载体,将改变催化活性物种和载体之间的相互作用,在一定...Syngas (H2 + CO) can be readily generated from carbon based materials including coal, natural gas, shale gas, biomass and even the organic waste. It is the starting material and intermediate of C1 chemistry, playing an important role in chemical industry. Catalytic conversion of syngas to higher alcohols (C2+-OH) is one of important subjects in C1 chemistry, owing to the potential use of higher al...学位:理学硕士院系专业:化学化工学院_物理化学学号:2052014115159
