淖毛湖煤与榆木混合方式对共热解耦合CH4/CO2重整产物影响研究
Effect of mixing modes on integrated process of co-pyrolysis of coal and biomass with CO2 reforming of methane to improve tar yield
摘要
Abstract
To investigate influence of mixing modes on integrated process of co-pyrolysis of coal and biomass with CO2 reforming of methane(CP-CRM),Naomaohu coal(NMH)and elm(ELM)were chosen and three mixing modes(NMH/ELM,ELM/NMH and Blends)were examined over Ni-based reforming catalysts prepared by ball milling,and compared with co-pyrolysis under N2 atmosphere(CP-N2).The results show that the products distribution was significantly affected by the mixing mode.Tar yield during CP-CRM under Blends model was higher than those of NMH/ELM and ELM/NMH,increasing by 35.29％compared with CP-N2.Meanwhile,light oil content in the tar was higher than those of NMH/ELM and ELM/NMH,but the pitch content was opposite.Phenols content in tar from Blends model was 19.52％higher than that of CP-N2,along with more free radicals in tar than that of CP-N2,which was mainly ascribed to the enhanced heat and mass transfer between raw material particles by mechanical mixing,making the co-pyrolysis process more complete.At the same time,the mechanical mixing was conducive to more efficient action of hydrogen-rich free radicals(such as·H,·CHx)on pyrolysis products,suppressing the secondary cracking and polymerization.The results provide a good guidance for regulating tar yield and compositions of the co-pyrolysis process.关键词
