What is Pyrolysis?

Pyrolysis is a process which is designed to produce a char which can be processed into a liquid with a heat value in the range of 50-80% of mineral fuel oil. 

The oil which pyrolysis produces a is called bio-oil, which is the basis of several processes for the development of fuels, chemicals and materials. There are various concepts around which pyrolysis is being devemoped. One concept is to use the residual fractions of the oil for hydrogen production after co-products have been separated making pyrolysis a possible component of a future hydrogen fuel based economy.

Pyrolysis produces energy fuels with high fuel-to-feed ratios, making it the most efficient process for biomass conversion, and the method most capable of competing and eventually replacing non-renewable fossil fuel resources.

So pyrolysis produces bio-oil, char, and synthetic gas from biomass. One company has developed what it calls "Fast pyrolysis" which operates at higher temperatures and over shorter time periods than other pyrolysis processes. They say that this converts more of the biomass into gas and oil, and less into charcoal. Fast pyrolysis is aimed at producing liquids for the direct application of heat and power in bio-refineries with typical applications of pre-conditioning of gasifier feedstock –producing liquids and gases as well as char and even slurry.

However, we are told that the fast pyrolysis of non-woody feedstocks can lead to the production of highly reactive liquids and can be rich in high tars with some product sbituminous in character and solid at room temperature leading to storage and processing issues.

Carbonscape would not initially be producing charcoal for biochar, but for industrial uses of charcoal, as a substitute for coal, because prices are rising internationally. Carbon credits will be earned for the treatment of wood waste into charcoal. Carbon dioxide produced in the biomass gasification step is constantly recycled into the reactor, thus eliminating the release of carbon dioxide into the atmosphere. It must be noted, however, that the paper sets forth only a conceptual framework.

Biochar is charcoal formed by low temperature pyrolysis. Higher temperature pyrolysis produces a more traditional charcoal. Biochar is charcoal formed by low temperature pyrolysis. Medium temperature pyrolysis produces a more traditional charcoal, high temperature pyrolysis produces activated charcoal.
