The　efficient　deoxygenation　of　renewable　biolipids　into　liquid　alkanes　within　the　diesel　range　is　a　key　protocol　for　producing　high-quality　biofuels.　In　this　work,　the　conversion　of　methyl　palmitate　and　raw　palm　oil　were　accomplished　utilizing　a　bifunctional　catalyst　of　Ni　catalysts　supported　on　B2O3-ZrO2　under　solvent-free　conditions.　Among　various　Ni　loading　ratios　investigated,　the　catalyst　featuring　a　10　%　Ni　loading　achieved　100　%　conversion　of　methyl　palmitate　and　84.4　%　of　liquid　yield,　with　approximately　65　%　being　C15　alkanes.　Additionally,　more　than　91　%　of　hydrocarbons　were　also　generated　from　raw　palm　oil.　These　results　can　be　attributed　to　the　synergistic　interplay　between　the　acid　sites,　following　B2O3　modification,　and　the　presence　of　Ni　species.　Furthermore,　the　analysis　of　product　distribution,　gas　product　detection　and　the　kinetics　calculation　strongly　supports　that　the　deoxygenation　process　of　methyl　palmitate　primarily　follows　the　hydrodecarbonylation　route,　leading　to　the　predominant　formation　of　C15　alkane.　©　2024
