Experiment research on biomass mixture pyrolysis by fix-bed

Pyrolysis experiments on powdered biomass mixtures were obtained by blending 13 kinds of common biomass in northern China such as straw,sawdust,branches and leaves of salix mongolica and saliz matsudana,alfalfa,etc.while guaranteeing the same fraction of each kind of biomass in the mixture were performed on fixed bed.Investigation on yields,heat values and components of gases obtained from the pyrolysis of the mixture at different pyrolytic terminal temperatures was conducted.Characteristics of the pyrolysis process and distribution of the pyrolysis products were studied.Valuable data and results were obtained,such as yield of different kinds of gas phase products,heat values and components of gas from the pyloysis and yields of different kinds of pyrolysis products.Comparison between obtained results and weighted mean value of corresponding parameters of pyrolysis process of each single biomass was drawn.Synergistic reaction of blended biomass in co-pyrolysis process was discussed.
