Pyrolysis of biomass economical and technical properties of feedstock and products
The use of pyrolysis for the exploitation of biomass is largely dependent upon the utility of the resulting pyrolysis products. After the process, the heating value originally existing in the raw product is largely contained in the oil and charcoal products. There are several possible ways of utilising the pyrolytic oil. In addition to use as a chemical raw material, its direct use as a fuel can largely be realised with the technology familiar in heavy fuel oil firing plants. However, a series of material values is still needed for the design of plant and equipment. The oil quality should be further improved through optimisation of process control procedures and of pretreatment measures. Larger obstacles stand in the way of the utilisation of charcoal. Some can be processed into active charcoal but most must be used as fuel. In a powdered condition, however, it possesses a low raw density and thus a small energy content relative to volume. By mixing the charcoal with a liquid medium (water and oil), it is possible to create a pumpable, easily transported fuel with a relatively high energy density. However, major problems remain in the application technology, particularly in atomisation and combustion.
