Performance investigation of the catalyst for 2-butanol dehydrogenation
Ling Qian;Taizhou Donglian Chemical Co. ,Ltd.;
The properties of YTDH-1G catalyst and reference catalyst A for dehydrogenation of 2-butanol were characterized by XRD,TPR,BET and N2 O titration method. Using a fixed-bed reactor,the catalytic activity of both catalysts for 2-butanol dehydrogenation and the selectivity to methyl ethyl ketone were studied under atmospheric pressure. The results demonstrated that the addition of ZrO 2into the catalysts could increase the dispersion of active component of catalysts and improve the reduction performance of the catalysts. The surface area and dispersion of Cu in YTDH-1G catalyst were much bigger than those of reference catalyst A. The catalytic activity of YTDH-1G catalyst and its selectivity to methyl ethyl ketone were obviously better than those of reference catalyst A. YTDH-1G catalyst exhibited strong adaptability to the process conditions and could be used under wide ranges of temperature and space velocity.
