In this experimental study, the effects of ethylene glycol/water ratio, ethylene glycol/acid ratio, NaBH4 concentration, acid concentration, and temperature were investigated. These ethylene glycol/water ratio experiments showed that the use of water alongside ethylene glycol negatively affects H-2 production. The hydrogen generation rate (HGR) values obtained for this ethylene glycolysis reaction with 1 M H3PO4 and 1 M CH3-COOH catalysts are 5800 and 4542 mLmin(-1), respectively. Also, the completion times of ethylene glycolysis reactions with these acids are 8 and 10 s, respectively. The n value obtained for ethylene glycolysis reactions according to the power-law kinetic model was 0.50. The activation energies obtained with H3PO4 (;)and CH3COOH catalysts were 24.45 kJ mol(-1) and 33.23 kJ mol(-1), respectively. (c) 2022 Hydrogen Energy Publications LLC. Published by Elsevier Ltd.
