Summary

  1. 1.
    The purpose of the program is to design and build a gasifier with a capacity of 50 tons of wood per day. It will be a fixed bed down draft vertical gasifier operating at a pressure of 10 to 15 bars and producing syngas for methanol synthesis. The heat in put needed for charcoal gasification is obtained:
    • or by the combustion with oxygen of the recycled pyrolineous gases,

    • or by electrical heating of the recycled gases.

    • the results obtained with a laboratory apparatus: gas composition and influence of pressure and temperature on the kinetics of pyrolisis and gasification,

    • the results obtained on a gasifier of identical layout which will soon be tested at Marcoussis. This gasifier has a height of 13,5 meters, an internal diameter of.6 meter and an outside diameter of 1,3 meter. It will be used both for extensive test of the key components and for test of the complete system: influence of temperature and pressure, influence of the mass flow of recycled gases… on the quantity and composition of gas produced.

     
  2. 2.
    The program will be conducted by Novelerg and carried out by three other Compagnie Generale d’Electricite (CGE) subsidiaries:
    • Les Ateliers et Chantiers de Bretagne,

    • CGEE-Alsthom,

    • Les Laboratoires de Marcoussis, the CGE research center.

    Technip, which has a large experience in the design of plants producing methanol from natural gas will bring its support for the problems related to methanol production from syngas.

     
  3. 3.
    The design and construction of the gasifier will benefit from:
    • the results obtained with a laboratory apparatus: gas composition and influence of pressure and temperature on the kinetics of pyrolisis and gasification,

    • the results obtained on a gasifier of identical layout which will soon be tested at Marcoussis. This gasifier has a height of 13,5 meters, an internal diameter of.6 meter and an outside diameter of 1,3 meter. It will be used both for extensive test of the key components and for test of the complete system: influence of temperature and pressure, influence of the mass flow of recycled gases… on the quantity and composition of gas produced.
