2-13　Hydrogenation of biomass extracts using metal–solid acid catalysts

Abstract

The aim of this study was to extract kerosene-soluble components by hydrocracking Soluble prepared from biomass using bifunctional catalysts consisting of Y zeolite (solid acid) and hydrogenation-active metals. Only 24.5% TSKS components were obtained from the Soluble, but the TSKS yield increased significantly when hydrogenated at 350°C for 120 min using catalysts. In the case of TI component, the yield was 13.2% without catalyst, but decreased with PtY catalyst. On the other hand, the TSKI yield decreased when the NiY catalyst was used. These phenomena were discussed in terms of the hydrogenation ability and acidity of the catalyst.
