Claims
- 1. In a process for producing synthesis gas by reacting a solid carbonaceous fuel with steam in the presence of a carbon dioxide acceptor to produce a synthesis gas rich in hydrogen with at least a major portion of the carbon dioxide so produced being reacted with said carbon dioxide acceptor to produce calcium carbonate and to provide sufficient heat to maintain a desired reaction temperature, an improvement comprising; the use of finely-divided wood as said solid carbonaceous fuel and using as the CO.sub.2 acceptor, a CO.sub.2 acceptor consisting essentially of calcium oxide supported in a refractory carrier matrix, said carrier having the general formula Ca.sub.5 (SiO.sub.4).sub.2 CO.sub.3 and wherein said calcium oxide is present in an effective amount up to about 50 weight percent based on the weight of said synthetic CO.sub.2 acceptor.
- 2. The improvement of claim 1 wherein said finely-divided wood is of a particle size less than about 4 Tyler mesh.
- 3. The improvement of claim 2 wherein said finely-divided wood is of a size consist from about 100 to about 8 Tyler mesh.
- 4. The improvement of claim 1 wherein said wood is dried to a water content below about 2.0 weight percent.
