“…The long reaction time also gives enough time for reactants transportation towards the catalyst active sites. Furthermore, the depletion rate of reactants increased over time, thus affecting the rate of hydrogenation and isomerization in which consistent with the findings of Belkacemi et al and Gabrovska et al [26][27] . The progress of C = C double bonds saturation leads for an accumulationfor IV decline which is normally associated with the TFA formation 28,2 .…”

Hydrogenation of vegetable oils is a heterogeneous process where the process factors influence the conversion and selectivity. A Statistical study was performed on a sunflower oil (SFO) hydrogenation process using Pd-B/g-Al 2 O 3 catalyst to study the effect of the process factors, including temperature, hydrogen pressure, agitation, catalyst dose and reaction time on the iodine value and trans fatty acid content of hydrogenated SFO. It was found that each factor has a noticeable effect on the iodine value and trans fatty acid content of hydrogenated SFO. The study was also aimed to find out the optimum values for the hydrogenation factors which are capable to decline the IV to 70 (g iodine per 100 g oil) as well as produce a minimum trans fatty acid content of the hydrogenated SFO. The optimum values were found to be 431 K, 1000 kPa, 1000 kPa, 0.29 % and 42.2 min for the temperature, hydrogen pressure, agitation, catalyst dose and reaction time respectively.

“…Composed of biogenetic amorphous silica, diatom shell is characteristic of macro/mesoporous structure and excellent thermal and mechanical stabilities [16][17][18][19]. As a low-cost and readily available mineral with highly developed porous structure, diatomite may be particularly suitable to be used as a support for the synthesis of magnetite nanoparticles.…”
