摘要:

生物炭具有环境友好、来源广泛、成本低廉等优点,作为催化剂及催化剂载体被广泛应用于热转化过程,但存在易结焦失活、产物定向调控机理尚不明确等问题。对生物质炭基催化剂应用于热转化过程的研究进行了综述,介绍了生物质炭基催化剂制备、改性(杂原子掺杂和金属负载)方案的研究现状。从常规催化热解、微波辅助热解、焦油脱除、酯化合成运输燃料和水热液化5个方面对炭基催化剂的应用进行讨论,并指出探索催化剂深层次的催化机理以及构建具有多级孔隙结构的炭基催化剂以定向生产高值化学品是未来的研究方向。

Abstract:

Biochar had the advantages of environmental friendliness, wide sources, and low cost. It was widely used as catalyst and catalyst carrier in thermal conversion processes, while there were problems such as easy coking and inactivation and the unclear directional regulation mechanism of product. In this paper, the research progress on the application of biomass char-based catalysts for thermal conversion processes was reviewed, and the research status of preparation and modification(heteroatom doping and metal loading) schemes of biomass char-based catalysts were introduced. The application of char-based catalysts was discussed from five aspects: conventional catalytic pyrolysis, microwave-assisted pyrolysis, tar removal, esterification synthesis of transportation fuels, and hydrothermal liquefaction. Exploring the deep catalytic mechanism of catalysts and construct multistage char-based catalysts with multi-stage pore structure for targeted production of high-value chemicals were a future research direction as the future research directions.

Key words: char-based catalysts, catalytic pyrolysis, bio-oil, tar reforming, microwave pyrolysis
