Claims2
An activated carbon catalyst, comprising a carbonaceous material and at least one compound containing nitrogen, the catalyst having a nitrogen content of the carbon framework of more than 0.4 wt.-% and less than 0.5 wt.-% and a pore volume of the micropores <1 nm of less than 0.2 cm3/g and a pore volume of the macropores >1 nm of less than 0.4 cm3/g.
An activated carbon catalyst, comprising a carbonaceous material and at least one compound containing nitrogen, the catalyst having a nitrogen content of between 0.8 and 1.5 wt.-%, a pore volume of the micropores <1 nm between 0.2 and 0.4 cm3/g and a pore volume of the macropores >1 nm between 0.4 and 0.6 cm3/g.
