摘要: 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 6 MPa, 反应温度为 245 oC 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 25.4 mol%. 2% 镍的加入使得该催化剂上乙二醇收率增至 46.0 mol%, 表明 Ni 与 WP 之间存在着明显的协同作用.

Abstract: 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.
