Continuous Pyrolysis Most Suitable For Bulk Raw Materials

Bulk raw materials such as palm shells, rice husks, sawdust, peanut shells, coffee husk and so, if will be charred or carbonized best suited with continuous pyrolysis. This is because the bulk of raw materials can flow or poured into a container such as a pipe. Retort type pyrolysis by an auger inside it will push along the retort and into charcoal at the outlet. JFBC continuous pyrolysis is one of them and is capable of producing charcoal up to 70 tonnes/day in its largest unit. Raw material with size upto 1 inch is accepted in the pyrolysis unit. It will be difficult when using batch pyrolysis because it will take a long time and process control also not easy. In the retort pyrolysis temperature, timing and heating rate control also easy to do. The process time on a continuous pyrolysis is also fast and very different to the type of batch that takes days and even up weekly.

In addition to the continuous pyrolysis will produce a number of side products that also have economic value, which is generally to be difficult in a batch pyrolysis. Pyrolysis by-products include wood vinegar / liquid smoke, bio-oil, tar and syngas. Utilization of wood vinegar / liquid smoke, among others as a fish preservative or rubber coagulant. Bio-oil is used as fuel for the boiler and can be upgraded to vehicle fuel. Tar also can be as fuel and syngas because large amount could be as a source of heat to electricity generation.
Some industries require charcoal in the size of the bulk because of the charcoal into a material that ready for them. Agricultural charcoal (biochar), charcoal for activated charcoal raw material in various purification industries from the food sector, mining and even oil and gas, hereinafter the steel industry and others. The bulk charcoal as raw material will reduce production costs for the downstream industry, if the particle size and shape according to the needs of the industry concerned or ready-made, so the cost of downsizing (size reduction) could be eliminated if use large-sized charcoals.
