Mesoporous carbon supported copper based catalyst, production and use thereof

摘要

This invention relates to a mesoporous carbon supported copper based catalyst comprising mesoporous carbon, a copper component and an auxiliary element supported on said mesoporous carbon, production and use thereof. The catalyst is cheap in cost, friendly to the environment, and satisfactory in high temperature resistance to sintering, with a highly improved and a relatively stable catalytic activity.

主权项

1. A mesoporous carbon supported copper based catalyst, comprising mesoporous carbon, a copper component and an auxiliary element supported on said mesoporous carbon,
wherein, the auxiliary element (expressed as oxide) is one or more selected from V2O5, Li2O, MgO, CaO, Ga2O3, ZnO, Al2O3, CeO2, La2O3, SnO2 and K2O, the copper component (calculated as CuO) is present in an amount ranging from 2 wt % to 20 wt % based on the total weight of the catalyst, the auxiliary element (calculated as the aforesaid oxide) is present in an amount ranging from 0 wt % to 3 wt % based on the total weight of the catalyst, and the mesoporous carbon is present in an amount ranging from 77.1 wt % to 98 wt % on the total weight of the catalyst, and further wherein the mesoporous carbon has a BET specific surface area ranging from 900 m2 g−1-3100 m2 g−1, a most probable pore size ranging from 2 nm to 8 nm, a pore volume ranging from 0.4 mlg−1 to 3.2 mlg−1, and a mesoporosity ranging from 50% to 100%.
