Abstract
AbstractThe fossil fuel has been recognized as the major source of energy in the whole world over the ages. It has got both merits and demerits. Recently, due to the increasing number of their uses in different sectors, the effect caused by their burnings becomes hazardous to the environment. Hydrogen gas is a new and renewable form of energy, and it is environmentally friendly. There is a wide number of methods for the production of hydrogen gas. Among the various methods of hydrogen gas production available, the production of hydrogen gas from Al-water reaction in the presence of aqueous NaOH solution is a viable technique of production. In the present work, the effect of temperature of the reaction, concentration of NaOH, size of Al flakes, and type of water on the rate of production of hydrogen gas have been studied. The reactions were carried out at temperatures from 303 to 333 K in a step of 10 K and NaOH concentration was taken as 1, 2, 3, 4, and 5 M. The maximum volume of hydrogen is found to be 1186 ml/g and 1167 ml/g of Al at 333 K and 323 K, respectively.KeywordsHydrogenAluminumReaction rateRenewable energy
