Abstract

Abstract:

To investigate the synergetic effects in co-pyrolysis of macroalgae and terrestrial biomass, enteromorpha clathrate (EN), rice husk (HU) and their mixtures with different proportions were used for pyrolysis in a fixed-bed reactor. The co-pyrolysis effects were studied via analyzing the yields of gas, liquid and solid, GC-MS analysis, FT-IR analysis, heating value of bio-oil and GC analysis of gas product. It was found that the co-pyrolysis resulted in an increase in gas yield but a decrease in liquid yield, which indicated that a significantly synergetic effect happened during the process, promoting the generation of more gas. In addition, the low molecules in bio-oil were strongly affected by the co-pyrolysis, and the increase in CH₄, C₂H₆, C₂H₄, C₃H₈ yields in gas production was observed. Besides, the alkali metals in EN ash could perform a catalytic role in promoting the cracking of large molecules, which proved the synergetic effects in co-pyrolysis of EN and HU.

摘要：

为了进一步探究大型海藻与陆生生物质共热解的协同效应，选取条浒苔与稻壳生物质作为代表进行了单样以及不同混合比例的共热解台架试验。通过三相产物产率的计算，以及生物油产物的GC-MS、FT-IR、热值分析和对气相产物的GC分析，研究了条浒苔与稻壳共热解协同效应的影响。共热解的气相产物产率在各个混合比例下均高于理论值，说明共热解对气相产物的生成具有促进作用，同时共热解气相产物中甲烷、乙烷、乙烯、丙烷为主的小分子烃类物质产率高于理论值，生物油中以乙酸为代表的小分子产物明显增多，分析认为条浒苔灰分中Na、K等碱金属具有促进大分子产物进一步裂解的催化作用，进一步验证了条浒苔与稻壳共热解的协同效应。
