Abstract: In a method of producing fuel for start-up to an automobile internal combustion engine which is continuously operated after start-up on alcohol and/or dissociated alcohol and/or liquid hydrocarbonthe improvement comprising the steps of:(a) providing a readily replaceable first container having an initial amount of hydride therein in fluid flow communication with said internal combustion engine,(b) heating said hydride whereby hydrogen is produced leaving a hydride product and a remainder of hydridesaid remainder of hydride being lesser in amount than said initial amount of hydride,(c) initially starting said engine,whereby hydrogen is produced from the hydride for initially starting said engine and said remainder of hydride without regeneration of hydride product is available for the next starting of said engine.

Abstract: In a process for producing synthesis gas by reacting a solid carbonaceous fuel with water in the presence of a carbon dioxide acceptor to produce a synthesis gas rich in hydrogen with at least a portion of the carbon dioxide so produced being reacted with the 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 the solid carbonaceous fuel.

Abstract: A method for producing a synthetic CO.sub.2 acceptor by feeding a mixture of finely divided silica and at least one finely divided calcium compound selected from the group consisting of calcium oxide and calcium carbonate to a fluidized bed; operating the fluidized bed at suitable conditions to produce pellets of synthetic CO.sub.2 acceptor and recovering the pellets of synthetic CO.sub.2 acceptor from the fluidized bed. Optionally, spent synthetic CO.sub.2 acceptor can be charged to the fluidized bed to produce regenerated pellets of synthetic CO.sub.2 acceptor.

Abstract: A synthetic CO.sub.2 acceptor consisting essentially of at least one compound selected from the group consisting of calcium oxide and calcium carbonate supported in a refractory carrier matrix, the carrier having the general formula Ca.sub.5 (SiO.sub.4).sub.2 CO.sub.3. A method for producing the synthetic CO.sub.2 acceptor is also disclosed.
