Abstract (en)
[origin: EP0153235A1] 1. A process for the production of synthesis gas, wherein a hydrocarbon substance of vegetable origin, such as a biomass product, is first gasified in a first reactor (1) at a moderate temperature lower than the melting temperature of the ash, with the production, in addition to usable carbon monoxide and hydrogen, of "inevitable" species such as unconverted carbon, hydrocarbons and tars, whereafter the inevitable species are converted at high temperature in a second reactor (2) into hydrogen and carbon monoxide, characterized in that an increase to the conversion temperature in the second reactor (2) is obtained by blowing in a gas flow previously heated to a temperature of between 3000 and 5000 degrees C by passing such gas through a plasma torch (4) disposed at the outlet of a circuit (3) via which gas is blown into the conversion reactor (2), the flow rate of the blown-in gas being controlled in dependence on the temperature and proportions of carbon monoxide and hydrogen already existing in the mixture leaving the first gasification reactor (1).
