We have demonstrated the co-existence of hydrocracking and hydrogenolysis pathways in the PP conversion on bifunctional Ru/TiO2-A-SG, which brings the question of whether the dual-pathway scheme is applicable to other less branched substrates. Thus, we compared the reaction of four substrates with various branching levels (quantified by the fraction of 3 C in total C, n-C16H34, no 3 C; LDPE, ~ 2% 3 C, squalane, structure see Scheme 2a, 20% C, and PP, 33% all substrates, yielding no C1-2, minimal C3, and high fraction of isomers (Table and Figure ), indicating that hydrocracking is present with all substrates. Since hydrogenolysis is not catalyzed by Ni and its rate is more sensitive to PH2 than that of hydrocracking, we used two parameters: 1)
