Synthetic clay-supported catalysts for coal liquefaction
- Univ. of North Dakota, Grand Forks, ND (United States)
Synthetic clays with nickel substitution in the lattice structure are highly active catalysts for hydrogenation and hydroisomerization and, consequently, have considerable promise for the catalytic upgrading of coal liquids. Nickel-substituted synthetic mica montmorillonite (NiSMM) was prepared and subsequently impregnated with molybdenum and sulfided. The reaction of model compounds with these catalysts in the presence of hydrogen has been investigated to provide mechanistic models for coal liquefaction. The results indicate that NiSMM has active Bronsted acid sites for hydrocracking and hydroisomerization. The hydrogen-activating ability of the molybdenum and nickel sulfide sites proximate to the acid sites results in effective depolymerization catalysis.
