半焦作为催化剂/载体催化焦油裂解研究

Study on Char as Catalyst or Support for Tar Cracking

半焦由生物质或煤原位制得,具有比表面积高、来源广泛、原料成本低廉等优点。通过对半焦制备条件、反应条件和负载金属等条件的优化,制备出的半焦或金属/半焦催化剂用于焦油裂解具有广阔的应用前景。阐述了半焦作为催化剂/载体用于焦油裂解的研究进展,并指出其亟需解决的问题,进而指导催化剂的设计。

Char is made of biomass or coal,which has advantages of inexpensive synthetic raw materials,high specific surface area and highly porous textural structures.And char or char supported metallic catalyst obtained by through optimizing preparation conditions,reaction conditions and supported metals shows great potential application in tar cracking.In this paper,the research progress of char as catalyst or support for tar cracking was elaborated,and the problems to be urgently solved were pointed out,which could guide the design of catalyst.
