Group (viii) catalysts for generation of green hydrogen and acetic acid from ethanol and its mechanism thereof

A process for generation of green hydrogen from ethanol reforming, comprising the steps of:

• a) reacting a base with a predetermined amount of a catalyst in a reaction vessel to obtain a first reaction mixture;
• b) adding preweighed amount of dry ethanol and distilled water under gaseous atmosphere to the reaction mixture of step (a) to obtain a second reaction mixture;
• c) heating the second reaction mixture obtained in step (b) in a pre-heated oil bath at a predetermined temperature for 36-48 hours and quantifying the gas by the use of burette;
• and
• d) analyzing the composition of the gas by gas chromatography (GC) and calculating the yields of gas and acetic acid;
• wherein,
• said catalyst is pincer group (VIII) complex catalyst;
• the predetermined amount of the catalyst of step (a) is 0.130 g, 1.158 mmol or 0.390 g, 3.48 mmol;
• the predetermined amount of base of step (a) is in a range of 0.2-1.5 mol % (0.0034 g;
• 4.64 μmol);
• the gas atmosphere of step (b) is argon atmosphere and the preweighed amount of dry ethanol and distilled water of step (b) is 0.271 ml, 4.635 mmol and 0.042 ml, 2.317 mmol, respectively;
• and
• the pre-determined temperature of the oil-bath of step (c) is in a range of 110-130° C.
