Embodiment Construction

[0008] Unless indicated to the contrary, all percentages herein are expressed in weight percent and temperatures are expressed in °C. A "transition metal" is any element of Groups 3 to 12 of the IUPAC Periodic Table of the Elements, ie elements with atomic weights 21-30, 39-48, 57-80 and 89-103.

[0009] Reducing agents suitable for use in the present invention include carbon, hydrocarbons, alkali metals, alkaline earth metals, transition metals, Al, Ga, Si, P, and metal hydrides. Examples of particular reducing agents include methane, ethane, propane, butane, syngas, coal, coke, Be, Mg, Ca, Al, Si, Ti, Sc, Y, La, V, Cr, Mn, Co, Ni , Cu, Zn, magnesium dihydride and calcium hydride. In one embodiment of the present invention, the reducing agent is a hydrocarbon or a mixture of hydrocarbons. In one embodiment of the present invention, the reducing agent is at least one C 1 -C 4 hydrocarbon. In another embodiment of the present invention, preferred reducing agents are Mg, Ca...

Abstract

A method for preparing sodium and boron from sodium metaborate by reacting sodium metaborate with at least one reducing agent.

Description

technical field [0001] The present invention generally relates to a process for preparing sodium and boron starting materials and for preparing sodium borohydride from sodium, boron and hydrogen. Background technique [0002] Existing methods of producing sodium borohydride are inefficient because these methods require the reactants to contain 4 moles of sodium for 1 mole of boron. The cost of sodium borohydride can be reduced if boron and sodium can be combined in the 1:1 molar ratio they are present in the product. [0003] Sodium borohydride is a convenient source of hydrogen. However, the use of sodium borohydride as a hydrogen source - as in fuel cell applications - produces borates, including sodium metaborate as a by-product. Regeneration of sodium metaborate to sodium borohydride would greatly reduce the cost of using sodium borohydride as a hydrogen source. A process for the preparation of elemental sodium and boron from sodium metaborate would provide a source o...
