Introduction
Biomass tar: a byproduct of agricultural and forestry wasters
TarGasifier system
Crop stalk,sawdust,wood bark,etc.
Introduction
The tar output accounts for 10% of the total amount of biomass
Causing the environment pollution
2,000,000,000 tons agricultural and forestry wasters per year in China (available 65%)
Introduction
The utilization technology of biomass tar:1. Fractionnation<110 ℃: as wood vinegar110-190 ℃:medium calorific value,as fuel and chemical material190-230 ℃:asphalt plasticezer、aitioxidants、technical creosote
2. Catalytic pyrolysisPermanent combustible gas(750-900℃ )
