Inhibiting effects during the co-conversion of lauric acid and anisole over Ni and NiMo catalysts
The co-hydroconversion of lauric acid and anisole was carried out over Ni and NiMo catalysts T=260 and 280 °C and pH2=40 bar. Ni/Al2O3 demonstrated a high activity in converting anisole to cyclohexane, but lauric acid conversion was suppressed over this catalyst. In the co-conversion of their mixture the phenolic had no effect on the conversion of the acid, but the latter prevented the cleavage of the C-O bond in both anisole and reaction intermediates. It was assumed that the successful conversion of anisole in its mixture with lauric acid required that a catalyst should provide the fast consumption of the acid component. Accordingly, NiMo/Al2O3 possessed a high activity in lauric acid conversion, and a high cyclohexane yield from anisole was observed after the complete consumption of the acid. The results of the present study can be useful for the rational design of a catalyst for the effective hydroconversion of bio-oil.
期刊介绍:
Applied Catalysis A: General publishes original papers on all aspects of catalysis of basic and practical interest to chemical scientists in both industrial and academic fields, with an emphasis onnew understanding of catalysts and catalytic reactions, new catalytic materials, new techniques, and new processes, especially those that have potential practical implications.
Papers that report results of a thorough study or optimization of systems or processes that are well understood, widely studied, or minor variations of known ones are discouraged. Authors should include statements in a separate section "Justification for Publication" of how the manuscript fits the scope of the journal in the cover letter to the editors. Submissions without such justification will be rejected without review.
