磷化钨催化转化纤维素制乙二醇

Catalytic Conversion of Cellulose to Ethylene Glycol over Tungsten Phosphide Catalysts

首次将磷化钨(WP)催化剂应用于纤维素的催化转化反应.结果表明,与碳化钨催化剂类似,WP催化剂也可高效地实现纤维素转化.在H2初始压力为6MPa,反应温度为245oC时,20%WP/AC(活性炭)催化纤维素高选择性地生成乙二醇,其收率为25.4mol%.2%镍的加入使得该催化剂上乙二醇收率增至46.0mol%,表明Ni与WP之间存在着明显的协同作用.

Tungsten phosphide （WP） showed good activity in the selective conversion of cellulose to ethylene glycol （EG）.At a H2 initial pressure of 6 MPa and temperature of 245 oC,EG yield reached 25.4 mol% over 20%WP/AC （activated carbon） and 46.0 mol% over 2%Ni-20%WP/AC,which demonstrated a remarkable synergy between Ni and WP.
