“…The consumption of fuel was also lower with hydrotreated oil in comparison to biodiesel blends. Caprotti et al 8 blended biodiesel (5%) in varying blends of iso-hydrotreated oil and diesel to run a pickup truck. The fuel consumption was found to decrease with the increase in hydrotreated oil in the blend.…”

Biomass-based fuels are gaining importance for operating a compression ignition engine as they can curb greenhouse gases and are a key for addressing the energy security. Hydrotreated oil is considered to be a potential drop-in fuel for the compression ignition engine as its cetane number is higher than fossil diesel. In this study, hydrotreated waste cooking oil and its blends (10%, 20%, 30%, 40% and 50% by volume) with diesel were prepared. The ignition probability of the test fuel samples was found using a hot-plate test setup. The neat hydrotreated fuel has higher ignition probability at a particular temperature than the other test fuels. The Sauter mean diameter of the test fuels was also observed using a Malvern Spraytec test setup. The results reveal that the neat hydrotreated fuel has higher Sauter mean diameter due to its high viscosity. As the percentage of the hydrotreated fuel in the blend decreases, the Sauter mean diameter decreases and diesel has the lowest Sauter mean diameter. The test fuels were also used to run a compression ignition engine. The results reveal a decrease in brake thermal efficiency with the increase in the hydrotreated fuel share in the blend. The heat release for the blends starts earlier than diesel and the peak heat release is also lower than diesel. The HC, CO and smoke emissions for the test blends decreases up to 30% blend. When the percentage of the hydrotreated oil is further increased, the emissions starts increasing. The NO emissions were lower than diesel for all the test samples. As compared to diesel, the maximum reduction in NO (neat), HC (30% blend), CO (30% blend) and smoke emissions (30% blend) is 23.2%, 14.4%, 13.83% and 13.3%, respectively.

“…54 A similar behavior was observed with RD produced from palm oil, with a reduction of 6.5%. 53 Figure were observed for RD2O and RD40. 36 The aforementioned is confirmed above on the differences between using Pt and Ni catalysts.…”

“…36 On the other hand, a mixture with 10% of RD obtained from palm oil was used, a similar performance was observed compared to the base fuel. 53 It is also observed that the higher the RD fuel content in the mixture, results in the lower power. 31 This behavior explains that the lower values are 34.4 and 35.7 MJ/L for RD and diesel, respectively.…”

“…34 Instead, Caprotti and collaborators studied, biofuel containing 30% of RD produced from Thai crude palm oil was used, with no significant CO reduction was observed. 53 However, the fuel obtained by catalytic hydroprocessing of Jatropha curcas oil reported a reduction of 16% of CO emissions due to enhanced combustion related to cetane number. 33 The reduction of emissions observed with RD20 and RD40 concerning diesel is due to diesel contains about 16% of aromatic compounds that require greater activation energy to start combustion.…”

“…In other cases, a reduction of 17% of emissions using RD prepared by Neste Oil has been reported, 54 in addition to a 7% reduction with the RD biofuel produced from palm oil. 53 The ignition quality and the cetane number of the RD20 and RD40 fuels can decrease the HC emissions. 32 The reduction of NOx emissions for renewable fuels at full load are shown in Figure 5(d), at 1800 rpm RD20, RD40, and RD40-3C…”

Pt/γ-Al 2 O 3 catalysts were prepared by incipient wet impregnation and tested in hydrodeoxygenation reactions for conversion of oleic acid to n-C 17 alkanes at optimal conditions. The high conversion of 96.5% to renewable biodiesel (RD) is justified with the characterization results, showing that the catalyst has good texture properties, presence of metallic Pt evidenced by 2θ reflections and binding energies, as well as adequate dispersion of active phase and nanoparticle size. 20% and 40% mixtures of RD with diesel were used. At full load a slight decrease in potency was observed when using RD mixtures and comparing them with petrodiesel; fortunately, the RD mixtures showed significant reductions in air pollutants, RD40 achieved reductions greater than 22% for CO, HC, and near 43% in emissions of smoke when compared to diesel.
