Modification of acidic groups over zeolite via calcination for the selectively catalytic transformation of 2,3-butanediol in ethylene glycol

Biomass and bio-derived chemicals can be transformed into ethylene glycol (EG) via catalytic hydrogenation, but a small amount of 2,3-butanediol (23BDO) is generated. 23BDO in EG was removed via dehydration...
