“…These features are consistent with a type IV mesoporous bio-based material [28]. These findings will further highlight the vital role of phosphoric acid in the pretreatment of bio-based material for catalysts, as reported in previous works [21,29].…”

Sulfonated kenaf seed cake (SO3H-KSC) catalyst, was synthesized to aid biodiesel production from palm fatty acid distillate (PFAD). It was chemically activated with phosphoric acid for an impregnation period of 24 h in order to enhance the porosity and the specific surface area of kenaf seed cake (KSC). After the carbonization and sulfonation, the resultant catalyst was characterized with powder X-ray diffraction (XRD), Brunauer–Emmett–Teller (BET), Fourier transform infrared (FTIR) spectroscopy, field emission scanning electron microscope (FESEM), NH3-temperature programmed desorption (NH3-TPD) and thermogravimetric analysis (TGA). The SO3H-KSC catalyst was amorphous in nature and had an acid density of 14.32 mmol/g, specific surface area of 365.63 m2/g, pore volume of 0.31 cm3/g and pore diameter of 2.89 nm. At optimum esterification conditions--reaction time 90 mins, temperature of 338 K, methanol:PFAD molar ratio of 10:1 and catalyst concentration of 2 wt.%—a free fatty acid (FFA) conversion of 98.7% and fatty acid methyl esters (FAME) yield of 97.9% was achieved. The synthesized SO3H-KSC catalyst underwent five reaction cycles while maintaining a fatty acid methyl esters (FAME) yield and free fatty acid (FFA) conversion of >90%. Thus, the SO3H-KSC catalyst was shown to be an excellent application of bio-based material as a precursor for catalyst synthesis for esterification of PFAD.

“…In addition, the existence of sulfonic groups on the surfaces of both CM‐SO 3 H and P‐C‐SO 3 H were confirmed by S 2p and C 1s XPS, as shown in Figure . The S 2p peak at 169 eV corresponds to sulfonic acid (SO 3 H), and the C 1s peaks at 285, 286, and 289.3 eV were assigned to CC, CO, and COO functional groups, meaning both catalysts contained carboxylic (COOH) and sulfonic acid (SO 3 H) functional groups . After the catalytic reaction, the FT‐IR absorption bands at 1032 and 1171 cm −1 that correspond to the OSO and SO 3 H groups disappeared due to leaching of the functional groups during the reaction (Figure d).…”

“…Acid‐functionalized carbon has been used for the simultaneous esterification and transesterification of vegetable oil that has a high content of free fatty acid. Greater than 95% yield of biodiesel was achieved within 3 h . The surface chemistry of the acid‐functionalized carbon affected the catalytic activity via a decrease in the methanolysis conversion of palmitic acid with fewer oxygenated functional groups on the carbon surface .…”

A sulfonated carbon material was developed and investigated as an environmentally benign catalyst for furfural production. The sulfonic acid functionality was introduced by sequential hydrothermal carbonization and sulfonation of xylose. The morphology and textural properties were examined by scanning electron microscopy and N2 sorption measurements, respectively. The presence of sulfonic acid on the surface was proven by both Fourier transform infrared spectroscopy and X‐ray photoelectron spectroscopy analysis. Meanwhile, the acid properties were studied using an NH3‐TPD profile. Two different sulfonated carbons that was activated with KOH before sulfonation and one that was compared. The KOH‐activated sulfonated carbon contained both a porous structure and a high sulfonic acid content that improved the furfural yield and selectivity by more than 50% compared to the nonactivated sulfonated carbon. The reusability of the catalyst was investigated by monitoring the furfural selectivity over several reaction cycles, and after the 3rd cycle, a reduction in the selectivity from 72 to 30% was observed. However, the acid‐functionalized carbon could still be useful for furfural production due to its low environmental impact in both the preparation and disposal steps. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1455–1461, 2018

The depletion of fossil fuel reserves and increasing demands for diesel are considered to be important triggers for many of the initiatives that have been taken to search for possible sources for the production of biodiesel from materials available within the country. It is possible to produce biodiesel from waste/used cooking oils (WCO) that is comparable in quality to that of fresh vegetable oil. Not only does reuse of WCO, which can otherwise harm human health, reduce the burden on the government of treating oily wastewater, disposing of the waste, and maintaining public sewers, it also significantly lowers the production cost of biodiesel. In the process of frying, oil undergoes many reactions, leading to the formation of a number of undesirable compounds, such as polymers, free fatty acids, and many other chemicals. This poses challenges in the transesterification of WCO. This article covers different techniques in the production of biodiesel from WCO.It also compares combustion, emissions, and engine performance characteristics of biodiesel from WCO as well as factors affecting biodiesel production from WCO and its economic feasibility.
