摘要
Abstract
Co-pyrolysis characteristics of low rank coal mixed with biomass(duckweed )in different proportions were studied in a dry distillation equipment, and focusing on the coal tar of the product with GC-MS in order to investigate the reaction mechanism of the co-pyrolysis between biomass and coal. Furthermore, the research studied on the pyrolysis mechanism with bio-mass added by thermogravimetric analyzer. The results show that low-temperature tar could be upgraded with the increasing of biomass content, straight chain alkanes and high-value chemicals such as naphthalene, phenol, anthracene were enriched. The biomass can do favor to the pyrolysis process of coal by reducing the temperature of coaPs pyrolysis and active energy(E), The co-pyrolysis process belongs to first-order kinetic reaction, and the synergetic effect was found during coal and biomass co-prolysis by comparing with the individual pyrolysis.关键词
