Catalytic Deoxygenation

Under nitrogen atmosphere, waste cooking oil (WCO) was deoxygenated in semi-batch experiments by using the nanorods of phosphate-activated carbon, which is derived from walnut shell and promoted by CaO as catalyst at 350 °C. The deoxygenation reaction showed high activity (> 48% hydrocarbon yield) and high selectivity towards decarboxylation/decarbonylation (deCOx) reactions via exclusive formation of green diesel C15 fraction (> 60%). The high activity and high selectivity were attributed to the good physicochemical characteristics of the catalyst, including improved metal dispersion, high surface area and high basic properties. Overall, this study demonstrates CaO/AC catalytic deoxygenation as a promising approach to produce liquid green diesel C15 from WCO under hydrogen-free atmosphere.

Waste cooking oil (WCO) that contained triglycerides and fatty acid derivatives can be transformed to green fuel that have similar properties to the fossil fuel. Hence, this study was focusing on the production of green fuel hydrocarbons from feedstock of waste cooking oil by deoxygenation process. The deoxygenation reaction of WCO was conducted using different loading of nickel (Ni) (5, 10, 15 and 20 % w/w) supported on commercial activated charcoal. Based on the catalytic deoxygenation (DO) reaction, the highest conversion of hydrocarbon was achieved when the reaction undergo using Ni20%AC as catalyst at 350°C for 3 hours under inert atmosphere. The present of the higher loading active metal showed high DO reaction by decarboxylation and decarbonylation pathways with high hydrocarbon yield of 83% and high selectivity of n-C15 and n-C17. DO reaction also favoured the optimum strength of acidity. This study revealed that Ni20%AC catalyst is a promising catalyst for the green fuel production in WCO.

<p><strong><em>Abstract: </em></strong><em>Glycerol is biodiesel byproduct and has high economic value, so it needs purification to get high purity.Crude glycerol was obtained from triglyceride transesterification with methanol and KOH catalyst. The aims of this research were purify glycerol from biodiesel byproduct and determine the suitable of adsorbent for bleaching of glycerol. Crude glycerol used in this research was from waste of cooking oil and kapokseed oil. In purification of glycerol from waste cooking oil is started by separate methanol and water by distillation. It followed byadding 6% acid solution (HCl, H<sub>2</sub>SO<sub>4</sub>, H<sub>3</sub>PO<sub>4</sub>). Glycerol was mixed with acid solution by 3:10 ratio and the solution was then filtrated to separate the salt.  The filtrate was then bleached by adding 2% weight adsorbent (activated carbon, bleaching earth and activated zeolite), then stirred for 30 minutes at 30 <sup>o</sup>C. The solution was settled for 120 minutes and then filtered by whatman paper. The results showed that the optimum density of glycerol was 1.26 g/ml with addition of H<sub>2</sub>SO<sub>4</sub> 6% volume and 0,5% water content. The brightest color of glycerol was light brown resulted from the adsorption process used bleaching earth.  </em></p><p><strong><em>Keywords: </em></strong><em>Glycerol, Activated Carbon, Bleaching earth, Activated Zeolite.</em><em></em></p><p> </p>

In this study, a novel idea was proposed to convert the polyethylene terephthalate (PET) waste drinking-water bottles into activated carbon (AC) to use for waste cooking oil (WCO) and palm fatty acid distillate (PFAD) feasibility to convert into esters. The acidic and basic char were prepared by using the waste PET bottles. The physiochemical properties were determined by employing various analytical techniques, such as field emission scanning electron microscopy (FESEM), thermogravimetric analysis (TGA), Fourier transform infrared (FTIR), Brunauer–Emmett–Teller (BET) and temperature-programmed desorption – ammonia/carbon dioxide (TPD-NH3/CO2). The prepared PET H3PO4 and PET KOH showed the higher surface area, thus illustrating that the surface of both materials has enough space for impregnation of foreign precursors. The TPD-NH3 and TPD-CO2 results depicted that PET H3PO4 is found to have higher acidity, i.e., 18.17 mmolg−1, due to the attachment of phosponyl groups to it during pretreatment, whereas, in the case of PET KOH, the basicity increases to 13.49 mmolg−1. The conversion results show that prepared materials can be used as a support for an acidic and basic catalyst for the conversion of WCO and PFAD into green fuel.
