三水磷酸钾耦合CaO对樟木粉热解特性及NOx前体释放特性的影响
Interconnection effect of CaO and tripotassium phosphate trihydrate on the pyrolysis characteristics of camphor powder and the release of NOxprecursor
摘要
Abstract
Using the biomass to produce high value-added chemicals by catalytic pyrolysis has broad application prospects. But the emission of NOxin pyrolysis process has adverse effect on the environment. The Thermogravimetric Analysis and Mass Spectrometry(TG-MS)were used to investigate the pyrolysis characteristics of camphor powder and the main characteristics of NOx precursor release during pyrolysis,and the interconnection effect of CaO and phosphate on the formation of NOxprecursors during pyrolysis of camphor powder was studied. The experimental results showed that with the addition of CaO and tripotassium phosphate trihydrate,,the release of volatile products increased while the yield of solid products decreased in the pyrolysis process of camphor wood powder;meanwhile,the ion flow intensity curve of the main NOxprecursors produced decreased during the mixed pyrolysis process. This showed that the interconnection effect of CaO and tripotassium phosphate trihydrate could improve the pyrolysis of camphor powder and make it more thoroughly; and the interconnection effect of CaO and tripotassium phosphate trihydrate could effectively restrain the first cleavage of nitrogen-compounds in the camphor powder,and indirectly reduce the production and release of HCN,HNCO,CH3CN; the interconnection effect of CaO and tripotassium phosphate trihydrate could postpone producing NOxprecursors during pyrolysis of camphor powder.关键词
