PRODUCTION OF HYDROGEN GAS FROM DRINK WASTE WITH ELECTROLYSIS WATER AND ALUMINIUM CORROSION PROCESS AS FUEL WELDING

Abstract

Hydrogen fuel is one of the alternatives. The existence of constraints in hydrogen-boundary feedstocks in nature causes us to think how to create hydrogen gas. The discovery of aluminum cans of waste which can be a source of hydrogen gas when mixed with acid or base is one of the most calculated means for producing sufficient quantities of hydrogen gas. Used aluminum contained in Coca-Cola, Green sands and Sprite cans as materials corrosion process with variation of electrolyte concentration 0,6 M, 0,8 M and 1 M. The result of research and data processing performed show that by comparing the three types of aluminum waste cans with different levels of produced hydrogen gas, it is found that more and more high concentrations of aluminum are used to produce more hydrogen gas. The largest volume of hydrogen gas is obtained from aluminum coca cola waste with a concentration of 1 M KOH of 0.175 liters (175 ml). The resulting hydrogen gas is then utilized as welding fuel with variations of flow rate and metal welding. The highest Specific Fuel Consumption is obtained when the steel welding is 6579.6186 Joule H2 / cm steel with H2 7L / min flow rate and within 100s the highest welding length is 1.6cm in aluminum welding with a 7L / min hydrogen rate
