Method and apparatus for processing of carbon-containing feed stock into gasification gas

A downdraft gasification method comprising the steps of

• providing a loading mechanism trunk,
• providing a drying zone
• providing a plasticization zone
• providing a pyrolysis zone
• providing a combustion zone
• providing a reforming zone
• providing a slag discharge zone
• supplying feedstock,
• forcing said feedstock through said loading mechanism trunk as well as through each of said drying zone, pyrolysis zone, combustion zone, reforming zone and slag discharge zone with a loading mechanism that comprises an elongated loading mechanism trunk and a feedstock feeder,
• causing said feedstock being forced through said loading mechanism trunk to form a plug that substantially hermetically separates said drying zone, said plasticization zone, said pyrolysis zone, said combustion zone, said reforming zone and said slag discharge zone from the atmosphere;
• causing formation and separation of steam from said feedstock in said drying zone,
• causing pyrolysis gases to form in said pyrolysis zone,
• separating substantially all of said pyrolysis gases from said feedstock in said pyrolysis zone, thereby causing separation of carbon char residue;
• and forming gasification gases.
