Tuning the properties of Ni-based catalyst via La incorporation for efficient hydrogenation of petroleum resin
文献摘要：
The hydrogenation of petroleum resin(PR)is an effective process to prepare high value-added hydro-genated PR(HPR).However,the preparation of non-noble metal-based catalysts with high catalytic activ-ity 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 hydro-genation.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.
