Structure of cobalt hydroxoaluminate and catalytic properties of the products of its reduction

Abstract

The structure of synthesized cobalt hydroxoaluminate (CHA) and course of thermolysis and reduction were investigated by XPA (including high-temperature x-ray diffraction), thermal chromatography, DTA, DTG, IR, and UV spectroscopy. It was shown that the activity the products of reduction activation of CHA in synthesis of hydrocarbons from CO and H2 is a function of the temperature of reduction and synthesis. It was concluded that hydrocarbons are synthesized on Co/CoAl2O4. The production of CHA are active in the same reduction temperature range as the previously studied cobalt cement catalysts.
