“…No KOH peak is detected, showing that K + is highly dispersed in the CaO, which led to the formation of K-CaO surface (Kumar & Ali 2012). As noted by Kabo et al (2015), the reaction between K and Ca might result in the weakening of Ca 2+ -O 2bond, which could possibly lead to an effective interaction with methanol, thus escalating its effectiveness as well as the conversion percentage. The purpose of conducting the TG analysis is to determine the ideal calcination temperature of the prepared catalyst.…”

This work focuses on the catalytic potential of K-impregnated staghorn coral as a catalyst in methyl esters production via methanolysis of waste cooking oil (WCO). The prepared catalyst was analyzed by Hammett indicators, XRF, Brunauer-Emmett-Teller (BET)-N2 adsorption method, ATR-FTIR, TGA, XRD and SEM to determine its physicochemical properties. ATR-FTIR and XRD results confirmed the formation of K 2 O species upon KOH impregnation, thus, resulting in good catalytic activity. Reaction parameters such as methanol to oil ratio, reaction time and amount of catalyst were evaluated to find out the best conditions for the transesterification process. About 89.51 ± 4.78 % of biodiesel contents were obtained under the optimum conditions.

Biodiesel is an alternative to biofuel that could help to reduce the use of fossil fuels and protect the environment. Evaluation of reaction kinetics provides information on reaction rates and mechanism which is necessary in evaluating catalyst’s effectiveness. In this research, zinc oxide (ZnO) nanostructures, nanoparticles, nanoflowers and nanotubes were base-modified with potassium to enhance their active sites and used in the transesterification process for study of kinetic parameters. The nanocatalysts were characterized with FESEM and biodiesel conversion monitored with 1H NMR. The result shows that both structure and base modification have influence on the kinetics parameters. In all the catalysts, activation energy falls within 26-82 kJmol-1indicating that the process was kinetically controlled and nanotubes has the highest rate constant of 0.0287 min-1, lowest activation energy of 59.40 kJmol-1and highest turnover frequency (TOF) of 0.026s-1. The results show that kinetic parameters of transesterification are not only defendant on catalysts’ basic or acid active sites but can also be influenced by structural modification. Therefore, the structural and K-modified ZnO nanoparticles have effect on the kinetic parameters of the tranesterification of rice bran oil (RBO) to biodiel and thus significantly reduce the use of fossil fuels in the environment
