The　hydrogenation　of　petroleum　resin　(PR)　is　an　effective　process　to　prepare　high　value-added　hydrogenated　PR　(HPR).　However,　the　preparation　of　non-noble　metal-based　catalysts　with　high　catalytic　activity　for　PR　hydrogenation　still　remains　a　challenge.　Herein,　a　La　promoted　Ni-based　catalyst　is　reported　through　the　thermal　reduction　of　quaternary　NiLaMgAl-layered　double　hydroxides　(NiLaMgAl-LDHs).　The　incorporation　of　La　is　beneficial　to　the　reduction　and　stability　of　Ni　particles　with　reduced　particle　size,　and　the　increased　alkalinity　effectively　mitigates　the　breakage　of　molecular　chains　of　PR.　As　a　result,　the　La　promoted　Ni-based　catalyst　exhibits　high　catalytic　activity　and　excellent　stability　for　PR　hydrogenation.　A　hydrogenation　degree　of　95.4%　and　96.1%　can　be　achieved　for　HC5PR　and　HC9PR　with　less　reduced　softening　point,　respectively.　Notably,　the　hydrogenation　degree　still　maintains　at　92.7%　even　after　100　hours’　reaction,　much　better　than　that　without　La　incorporation　or　prepared　using　conventional　impregnation　method.　©　2021　The　Chemical　Industry　and　Engineering　Society　of　China,　and　Chemical　Industry　Press　Co.,　Ltd.
