摘要
文章将椰壳活性炭作为催化剂,分别采用电加热和微波加热的方式,对棕榈壳热解挥发分进行了催化重整试验。结果表明:2种加热方式下的催化重整均促使生物油向气体转化,其中,微波加热方式下的生物油转化率为95.5%,电加热方式下的生物油转化率为74.5%;微波加热方式在生成苯酚方面展现出了明显的促进作用,在此加热方式下,生物油中的苯酚含量达到了83.0%,比棕榈壳直接热解时的苯酚含量提高了51.4%,实现了苯酚的富集,较好地提升了生物油的品质;对催化重整后的气体组成进行分析时发现,2种加热方式均提高了H_(2)和CO的含量;以活性炭为催化剂,在微波加热方式下催化重整棕榈壳热解挥发分可实现苯酚和合成气的共同制备。
The characteristics of products from catalytic reforming of biomass pyrolysis volatile matter using activated carbon as catalyst under electric and microwave two heating methods were compared.The results showed that both heating methods facilitated the transformation of bio-oil to gas.The bio-oil conversion rate under microwave heating can reach 95.5%,while the bio-oil conversion rate under electric heating was 74.5%.The microwave heating showed a significant promotional effect in the generation of phenol.Under this heating method,the content of phenol in the bio-oil reached 83.0%,which was a 51.4%increase compared with the phenol content obtained by direct pyrolysis of palm kernel shell,significantly improving the quality of bio-oil and achieved the enrichment of phenol.Analysis of the gas composition after catalytic reforming revealed that both heating methods significantly increased the content of H_(2) and CO.Catalytic reforming of palm kernel shell volatile matter over activated carbon catalyst under microwave heating method has excellent potential for poly-generation of phenol and syngas.
