Making fuels from almost any organic material

By Paul Grad |

Adgex Ltd. (Sydney, Australia; www.adgex.com) is marketing a plant, tradenamed “Green Blaze,” for processing organic raw materials by means of high-speed ablative pyrolysis. According to the company, the plant (flowsheet) can be adapted to convert into synthetic fuel almost any organic material, including coal, oil wastes, municipal solid waste, industrial and commercial waste, woodchip and sawdust, animal manure and fat, food residues, sewage sludge and other carbon-containing materials. The process of high-speed ablative pyrolysis has the advantage that it allows shifting the balance toward either gaseous or liquid products by adjusting the pyrolysis temperature. The company claims its process produces far greater amounts of heat and fuel, and is far cleaner than other designs. The process’ efficiency and clean operation are achieved by careful preparation of the feedstock, by using a very small reaction area subjected to a very high rate of heat ingress and with continuous and rapid withdrawal of pyrogases from the reaction area. According to the company, combustion heat of gaseous pyrolysis products can reach up to 12.9 MJ/m3 by virtue of the high hydrocarbon content. Output of gaseous raw material can reach 70 wt.% of dry…
