At around 500 C the process favours pyrolysis oil, or pyoil, and acetic acid, in case of a biogenic feedstock. Thermal decomposition of organic components in the waste stream starts at 350C-550C and goes up to 700C-800C in the absence of air/oxygen. It has the advantage of being relatively simple and adaptable to a wide variety of feedstocks and it can produce several usable products from typical waste streams. Combustibles constitute on average about 60% of the weight of MSW and result in an average heating value ("as received" basis) of about 3,000 to 6,000 Btu/Ib. Typically a person produces MSW at a rate of 0.5 kg to 2.5 kg per day and the waste has carbon content at 20-35 percent[1,2].These numbers are dependent on area, culture and income levels.

A key element of a CELSS is a means for solid waste resource recovery. Moving up to 700 C we begin to get more methane, or pygas, produced. Pyrolysis of waste tires with partial oxidation in Active carbon production from used tire in two-stage procedure: industrial a uidized-bed reactor. The word is resulting from two Greek words: 'pyro', which means fire, and 'lysis', which means disintegration into integral parts. Pyrolysis operates at around 500oC without oxygen to produce solid (char), liquid (tar), and gas [1].In the process of Pyrolysis, in between the two electrodes the arc is produced by using the DC power supply, where the high voltage and high frequency generator is used to strike that plasma. Rapid/Fast Pyrolysis : Primarily to produce Bio-Oil and Gas -Biomass is very rapidly heated (~1000-10,000 C/s) to a temperature around 650 C-1,000 C depending if bio-oil or gas products are desired. In accordance with these rules, it is the duty of every "occupier" i.e. Target analytes are typically very high molecular weight compounds. What can I do for you?
