“…It could be explained that introduction of metal oxide improves the catalyst redox property, which may be favorable for the oxidative dehydrogenation on the metal active sites of saturated alkanes to unsaturated olefins, which are easier for b-scission to produce light olefins according to Refs. [6][7][8]. So, combined modification by alkaline treatment and Fe-Ti-loading on ZSM-5 can improve total light olefins by 0.69 wt% in the cracking of Canadian LGO, which is simple and feasible for improving light olefins yield in catalytic cracking process.…”

“…Maia et al introduced nickel into ZSM-5, and their prepared Ni-ZSM-5 exhibited the bi-functional catalysis performance to enhance light olefin production. Metallic nickel sites could still be formed via a partial reduction by n-hexane, isobutane and nbutane during the catalytic test [7,8]. In our previous work, the synergistic interaction of Fe and Ti with micropore ZSM-5 zeolite was investigated [9].…”

“…Hydrocarbon chemistry over acid catalysts is governed by bimolecular reactions [26,28,46] and particularly by hydrogen transfer reactions 32 . For instance, hydrogen transfer reaction between olefins and naphthenes leads to the formation of more refractory paraffins [47,48].…”

The production of green hydrocarbons in the standard refinery has significant potential to reduce our reliance on oil and shorten the path to sustainability. Second-generation biomass can help to achieve this objective yet presents important drawbacks. It is majorly composed of reactive compounds and features low density. These features could be overcome by previously transforming the biomass by ketalization reaction into a bio-crude mainly composed by ketal-sugar derivatives. In this work, a representative compound of the bio-crude class, i.e. 1,2:3,5-di-O-isopropylidene-α-d-xylofuranose (DX) were used in up to 50 wt.% mixtures in n-hexane was converted in a laboratory scale fluidized catalytic cracking (FCC) reactor. A commercial and a simplified FCC catalyst were used. Converting a mixture of 30% DX in n-hexane in the presence of a commercial catalyst gave 42.3% aromatics in the liquid product, while pure n-hexane gave merely 8.9%. The use of deactivated catalysts further reduced the coke yield to half of the fresh one. The nature of the coke on the spent catalyst is exclusively composed by carbon and hydrogen, demonstrating that DX is easily deoxygenated. The n-hexane conversion slight reduced in the presence of DX, and did not reduce the stability of the catalyst through micropore blocking. This work demonstrates that adding DX allows to contributes to high bio-aromatic production in FCC and that products distribution is remarkably affected by the type of catalyst used.

“…However, nickel based catalysts display high catalytic activity but low selectivity to isobutene for isobutane dehydrogenation due to the rapid crack reactions, and main products will be methane and coke [19,20]. Recently, Ni 2 P has been used as a new class of catalyst for hydrodesulfurization (HDS) [21,22] and hydrodenitrogenation (HDN) [23,24] of petroleum feed stocks, exhibiting an excellent catalytic performance.…”
