Synthesis of alcohols from syngas and alcohol chain growth over copper-cobalt based catalysts
- Dalian Institute of Chemical Physics (China)
The alcohols synthesis from syngas was studied under pressure (6.0 MPa). The higher alcohols formation increased with the cobalt content, caused probably by the augmentation of the number of the Co-Cu bisites, and the higher hydrocarbons augmented simultaneously, explained by common reactional intermediates. The TPR, CO Chemisorption, XRD and TPD experiments were performed for the catalyst characterizations. There were some strong interactions between cobalt and copper, and the cobalt addition onto CuLaZr catalyst may have three important effects on alcohol chain growth: an increase of the formation of hydrocarbonated species, an augmentation of the CO insertion property, and a modification of the hydrogenation capacity of system, as supported by the tests of reactivities and those of probe molecules. The influences of different pretreatments were also investigated.
