“…There is a marked and clear effect of the C/F mass ratio on the values of the cetane index obtained, which are a consequence of the aforementioned changes in the composition of the LCO fraction. The lower the concentration of aromatics, especially polyaromatics, in the LCO fraction, the higher the cetane index will be [23]. Thus, the cetane index increased with the C/F mass ratio, and values of 40.5, 44.7 and 54.9 were obtained for 0.05, 0.075 and 0.1 g catalyst g feed −1 , respectively.…”

The effects that the catalyst-to-feed ratio have on the yields of products and composition of the naphtha and light cycle oil (LCO) fractions in the hydrocracking of a blend composed of high-density polyethylene (HDPE) and vacuum gasoil (VGO) using a PtPd/HY catalyst were assessed. The hydrocracking runs were carried out in a batch reactor fixing the following operation conditions: 420 °C, 80 bar, 120 min and an HDPE-to-VGO ratio of 0.2 gHDPE gVGO−1, varying the catalyst-to-feed mass ratio within the 0.05–0.1 gcatalyst gfeed−1 range. The obtained results exposed that a catalyst-to-feed mass ratio of 0.075 gcatalyst gfeed−1 provided the best results, since the conversion of the heavy cycle oil (HCO) fraction and of the HDPE offered quite high values (73.1 and 63.9%, respectively) without causing an excessive overcracking in the form of gas products (the yield of gases was of 25%). Moreover, an interesting yield of naphtha (37.0 wt%) with an RON within the commercial standards (92.5) was obtained. With regard to coke formation, not-so-developed structures were formed for a catalyst-to-feed mass ratio of 0.075 gcatalyst gfeed−1, easing their combustion and presumably extending the lifespan of the catalyst.

“…RSO disappearance rates over the 0.3NiMo/Al 2 O 3 catalyst were greatest, being between 2 and 3 times greater than those over Mo/Al 2 O 3 and Ni/Al 2 O 3 catalysts, respectively. In regard to the overall selectivity, the NiMo/Al 2 O 3 catalysts followed the HDO and (H)DCO 2 pathways; however, Ni/Al 2 O 3 goes by (H)DCO 2 , while Mo/Al 2 O 3 prefers the HDO route. − …”

The production of renewable fuels by co-hydrotreating is considered a very promising solution to make use of the existing petroleum refining infrastructure. Differently to stand-alone hydrotreating, co-hydrotreating requires lower investment costs. To design a co-hydrotreating of vegetable oil and gas oil, various issues need to be properly examined. This work reports an extensive review and discussion of such issues to provide a clear understanding of the effects on feedstocks, operating conditions, catalysts, corrosion, and product quality. The discussion also includes the challenges for modeling and simulation of co-hydrotreating processes.
