摘要: This work concerns the influence of hydrogen sulfide partial pressure on activity in hydrodeoxygenation and associated reactions a CoMo/Carbon catalyst for transformation guaiacol, ethyldecanoate 4-methylacetophenone. has been studied over wide range pressures, from 10 to 150 kPa, under total 7 MPa, at reaction temperatures 270 200 degrees C. An inhibition effect is observed hydrogenolysis pathway guaiacol conversion dehydroxylation. The 4-methylacetophenone also inhibited by sulfide. results have interpreted basis existence different active sites responsible hydrogenolysis, hydrogenation acid catalysed reactions. increase would decrease average degree reduction inhibit pathway, more than one. are compared those with alumina supported catalysts hydrodesulfurisation.
