Abstract: The present invention relates to processes for producing borohydride compounds. In particular, the present invention provides efficient processes and compositions for the large-scale production of borohydride compounds of the formula YBH4 by the reaction of a boron-containing compound represented by the formula BX3 with hydrogen or an aldehyde to obtain diborane and HX, and reacting the diborane with a Y-containing base selected from those represented by the formula Y2O, YOH and Y2CO3 to obtain YBH4 and YBO2. Y is selected from the group consisting of the alkali metals, pseudo-alkali metals, alkaline earth metals, an ammonium ion, and quaternary amines of the formula NR4+, wherein each R is independently selected from hydrogen and a straight- or branched-chain C1-4 alkyl group, and X is selected from the group consisting of halide ions, —OH, —R′ and —OR′ groups, chalcogens, and chalcogenides, wherein R′ is a straight- or branched-chain C1-4 alkyl group.

Abstract: The present invention relates to a composition and method for storage and controlled release of hydrogen. In particular, the present invention relates to the use of borohydride based solutions as a hydrogen storage source and a catalyst system to release hydrogen therefrom.

Abstract: An engine cycle that is carried out in a reciprocating piston/cylinder engine consists of a working stroke in which exothermic decomposition of at least one liquid compound is caused to occur without combustion so as to produce a gaseous product of the decomposition that drives the piston along the cylinder in one direction and an exhaust stroke in which the products of the decomposition are exhausted from the cylinder upon return movement of the piston.

Abstract: This invention relates to an improved process for rapidly converting essentially solid carbonaceous material to essentially liquid and gaseous hydrocarbon products wherein a rapid and economical method of separating the components of the super-acid system from the liquified hydrogenated products is used.

Abstract: Essentially solid carbonaceous material such as coal is rapidly converted to a high percentage of liquid hydrocarbon products by first reacting said material with an acid to form carbon addition products which then are reacted with a Group V halide ion-acceptor system (super-acid system), the acid content of which is greater than the Group V halide content, and thereafter with a hydrogen donor source. All phases of the process may be carried out at atmospheric pressure and relatively low temperatures, thus making said process far more economical than known coal liquification processes.
