Recycling of organic waste is an increasingly hot topic in recent years. This issue becomes even more interesting if such processing will serve a source of pure hydrogen or the raw material for the fuel production will be obtained as the result of that recycling. A process of high-temperature decomposition of a lignite (a non-hydrolysable complex organic
compound) was studied on the plasma gasification reactor PLASGAS, where water-stabilized plasma torch was used as a source of high enthalpy plasma. The plasma torch power was 120 kW and allowed heating of the reactor to more than 1000 0C. The material feeding rate in the gasification reactor was selected 30 and 60 kg per hour that could be compared with small industrial production. An efficiency estimation of the thermal decomposition process was done. A balance of the torch energy distribution was studied as well as an influence of the lignite particle size and an addition of methane (CH4) in a reaction volume on the synthetic gas (syngas) composition (H2+CO). It was found that the ratio H2:CO had values in the range of 1,5 to 2,5 depending on the experimental conditions. The recycling process occurred at atmospheric pressure that was one of the important benefits because of the lack of expensivevacuum pump systems.
