WebbA biochar reactor is a kind of equipment to make charcoal without oxygen under a high-temperature situation. The raw materials can be coconut shell, wood, sawdust, agricultural stalks, bamboo, coffee seed, and other kinds of biomass waste. A good biochar reactor can serve customers for 5-8 years.

Torrefaction of biomass in a continuous rotating screw reactor

A screw pyrolysis reactor is shown in Fig. 2.5. These reactors apply mechanical drives to transport the biomass. They share similar principles with ablative reactors regarding transferring the heat from reactor walls, but the biomass may also be mixed with preheated metal or ceramic balls or sand. WebbThe reactor combines the advantages of screw reactors with the high temperature filtration, in order to produce particle and ash free vapors and condensates, respectively. Experiments were carried out at temperatures between 350°C and 500°C. The yield of the char decreased from 66.7wt.% to 53.0wt.%. crystal alpine inn
