不同生物炭微波热解生物质特性研究

Study on Characteristics of Biomass in Microwave Pyrolysis of Different Biochars

随着社会的高速发展能源也在大量消耗,寻找可持续发展的绿色能源成为了广大研究学者的研究重点,生物质能被称为是21世纪主要的绿色能源,其开发利用是缓解未来能源危机的主要途径之一。本文以自主开发的微波热解生物质系统为实验平台,龙眼壳、龙眼核、草、花生壳、荔枝壳以及木屑等6种不同的生物炭为研究对象,研究相同条件下荔枝壳生物质的微波热解特性。结果表明,以龙眼壳生物炭为吸波剂获得的气相产率和氢气体积分数最高,分别为51.12 wt.%和31.50 Vol%;以草生物炭为吸波剂的液相产率最高为39.40 wt.%;木屑生物炭为吸波剂的固相产率最高为32.84 wt.%。

With the rapid development of society,energy is also consumed in large quantities,the search for sustainable development of green energy has become the focus of research scholars,biomass energy is known as the main green energy in the 21st century,and its development and utilization is one of the main ways to alleviate the future energy crisis.In this paper,the self-developed microwave pyrolysis biomass system was used as the experimental platform,and six different kinds of biochar,including longan shell,longan core,grass,peanut shell,lychee shell and wood chips,were used as research objects to study the microwave pyrolysis characteristics of lychee shell biomass under the same conditions.The results showed that the gas phase yield and hydrogen gas integration number obtained by using longan shell biochar as the absorber were the highest,which were 51.12 wt.%and 31.50 Vol%,respectively.The highest liquid-phase yield of grass biochar as absorber was 39.40 wt.%.The highest solid phase yield of sawdust biochar as absorber was 32.84 wt.%.
