“…The technic of determining oxygen in organic compounds by catalytic hydrogenation received a major advancement in the suggestion made by Russell and coworkers (44,73,74,75) that the nickel methanation catalyst prepared by the reduction of nickel oxide be replaced by a promoted nickel catalyst obtained by the reduction of a mixture of nickel and thorium oxides prepared in a special manner.…”

“…(73). Russell and coworkers (73,75) recommended regenerating the catalyst by first oxidizing it to remove deposited carbon and then reducing it. It has been claimed that the catalyst is rendered more resistant to poisoning by sulfur if it is reduced at 450°C.…”

“…For the analysis of compounds containing sulfur, it has been recommended that a thoria-promoted nickel catalyst supported on granular quartz be used (75). The thin layers of nickel present are readily activated by reduction in hydrogen overnight at 500°C.…”
