Gasification is a chemical-physical process for transforming a solid fuel (wood, agricultural residuals, waste) in a gas fuel. The process consists of 3 phases:

  • first phase of desiccation to obtain dehydrated materials;
  • second phase of pyrolysis to obtain a partial distillation of wood ;
  • third phase of gasification during which the pyrolysis products react with the gasification agent creating different products, among which some fuels.

At present the Trisaia ENEA Research Centre studies the gasification with fixed bed and with fluid bed , through the testing of various kind of gasifycators used for electric energy production.

Some typical regional materials are used to this aim; olives, turkey oak, oak, agricultural residuals (almonds shell, apricots stones). The tests have been made with different powers, thus determining specific consumptions, pressures and temperatures on the plant. The technological hall for gasification is constituted by:
