Kinetic study of fast pyrolysis of sawdust in a conical spouted bed reactor in the range 400-500 degrees C

An original reactor (a conical spouted bed reactor) is used for the kinetic study of Pinus insignis sawdust pyrolysis in the range 400-500 degreesC un der the usual conditions of this reactor for pyrolysis in a continuous regi me. The equipment meets the requirements for pyrolysis kinetic study (bed i sothermality, high mass and heat transfer between phases and short residenc e time of gaseous products). The results of yield of products are evidence of the good performance of the conical spouted bed reactor for obtaining a liquid product, with a maximum yield of 70wt% in the range 440-460 degreesC .
