The Background of Pyrolysis Technology
Pyrolysis technology is a new solid waste treatment technology that was researched and developed in
the recent years. In the beginning of the year 1990, the foreign scientists found the extremely harmful
carcinogenicity composition to humans - dioxin in the refuse incineration process. Therefore, westerndeveloped countries studied the incineration treatment which will produce secondary pollution, and at the same time, invested heavy capitals to researching and developing the new waste treatment technology. Generally pyrolysis technology is optimistic by the various national environmental experts who agree that pyrolysis technology is a new road for organic solid waste harmless treatment, reduction, and resource.
Pyrolysis Principle:
Pyrolysis is using the heat instability of organic solid waste, in anaerobic or anoxic conditions by
absorbing heat and decomposed into small molecules, and the final product combustible
pyrolysis gas, tar and char with high quality.
Reaction Equation:
Pyrolysis Products:
• Gas ProductsmethaneethaneHydrogen Carbon monoxide
• Liquid ProductsCH3OHCH3COCH3C2H5COOHCH3CHO tar mineral spirits
• Solid Productscokecarbon black

Adiabatic and anoxic
-
Because the produced fuel oil of agricultural waste such as Almond Shells occupies a low rate, we
process a small amount of fuel oil all into combustible gas by temperature. The partial combustible gas
can be supplied to our system, the rest will partly be generated electricity to national grid by gas
generator.
-
Pyrolysis equipment start-up stage, the whole pyrolysis reaction calories is provided by external
energy (nature gas), reaction after stability provided by the pyrolysis reaction of combustible gas. The
main composition of combustible gas is methane, ethane, hydrogen, carbon monoxide, and so on,
and so this gas will supply the combustible furnace after purification treatment , due to the
combustible furnace uses this gas fuel, so the blue gas of combustible furnace need the slight
treatment only, it can meet the emission standard.
Cost Accounting
According to our test data obtained from low temperature pyrolysis agriculture waste-almond shells:
-
The 40% combustible gas will be used ourselves as energy demand, and the remaining 60% will be generated into electricity power.
-
Wood vinegar is widely used in agriculture, it can also be used as plant growth promoters, soil conditioner, deodorant agent, feed additives, organic fertilizer, and other products.
-
Biomass carbon can suppressed, forming as fuel it is also a kind of excellent soil modifier and organic carbon fertilizer; biomass carbon has good water retention and a slow-release effect.
