HYDROGEN GENERATING COMPOSITION, REACTOR, DEVICE AND HYDROGEN PRODUCTION METHOD

摘要

The present invention discloses a hydrogen generating composition, reactor, device and hydrogen production method. The composition includes sodium borohydride and a filler. The filler is a substance having a chemical stability and a water solubility of less than 10 g per 100 g of water under an alkaline or neutral condition at a temperature of 130° C. to 140° C. The filler has a bulk volume of 0.02-16 times the bulk volume of the sodium borohydride. A mass ratio between the filler and the sodium borohydride is less than or equal to 2:1. The filler has a bulk density of less than 16 and has a mean particle size smaller than that of the sodium borohydride. The present invention has a high hydrogen production density, adequate reaction, lower cost and is environmentally friendly, practical and simple to pause and restart.

主权项

1. A sodium borohydride-containing composition for generation of hydrogen, comprising sodium borohydride and a filler, wherein the filler is a substance having a chemical stability and a water solubility of less than 10g per 100g of water under an alkaline or neutral condition at a temperature of 130° C. to 140° C., where the chemical stability is an absence of decomposition of the substance and an absence of a chemical reaction with the sodium borohydride or water, and wherein the filler has a bulk volume of 0.02 to 16 times a bulk volume of the sodium borohydride, a mass ratio between the filler and the sodium borohydride being no greater than 2:1, the filler having a bulk density of less than 16, the filler having a mean particle size smaller than a mean particle size of the sodium borohydride, and wherein the alkaline condition is an alkalinity resulting from moisture-caused hydrolysis of the sodium borohydride or a reaction product NaBO2 thereof, and wherein the chemical reaction does not include simple hydration and the decomposition does not include simple dehydration.
