“…Oleate. High yield could be obtained with fewer substrates, but when the amount of substrates multiplied, the catalytic activity may be a ected by mass transfer resistance [35][36][37]. In order to ensure that the catalyst still has excellent catalytic performance in the presence of a large number of substrates, the large-scale reaction was carried out.…”

Biomass-based polymers are eco-friendly, nontoxic and biodegradable materials. In this work, in order to prepare green, low-cost and high-efficient catalysts under mild conditions, we chose biomass-based chitosan as raw material and prepared a new solid acidic catalyst by an acid functionalization method. FT-IR, XRD, SEM, TGA, BET, neutralization titration and other analytical methods were used to characterize the catalyst. The results showed that CS-SO3H morphology exhibited a sphere of about 10 μm diameter, and the acid density was as high as 3.81 mmol/g. The catalyst exhibits good catalytic activity in the esterification of oleic acid and methanol, which is a model reaction of the pre-esterification process in the preparation of biodiesel from feedstocks with high acid values. Under the optimum reaction conditions (15/1 methanol/oleic acid mole ratio and 3 wt% catalyst dosage at 75°C for 3 h), the yield of methyl oleate can reach 95.7%. Even if the mass of oleic acid in the reactant increased to 20 g, solid acid showed good catalytic performance, and the yield of methyl oleate was 94.4%. After four times of reuse, the yield of the catalyst can still reach 85.7%, which indicates that the catalyst has good catalytic activity and stability, and has potential application prospects.

“…17 Under the HTHP system, hydrogen atoms attached to the surface of the catalyst cleave and subsequently link with FFAs, continues with catalysing into methyl ester (ME). 12 The preliminary transesterication was carried out at a nonoptimized transesterication conditions: catalyst amount of 1 wt%, methanol to WCPO molar ratio of 6 : 1, operating temperature of 80 C, and mixing intensity of 300 rpm. At the end of each transesterication reaction, the sample was centrifuged to separate the catalyst from other liquid parts.…”

“…The combination of these characteristics increases the penetration of the reactants easily to the active sites which consequently increases the rate of production. 11,12 Moreover, sulfonated mesoporous metal oxide catalyst prevents agglomeration of the molecules of water around the active sites that signicantly improves the yield of nal product.…”

“…The initial program of B5 in 2013 that uses palm oil as a feedstock was implemented, whereby B5 consists of 5 % palm methyl ester blend with 95 % petroleum diesel [4]. The primary reason for the production of biodiesel is to lower exhaust emission, as well as to produce a sulfur and carcinogenic free fuel [5]. Since then, biodiesel production continued with the implementation of B7 in 2015 and B10 which is yet to be introduced.…”

This paper presents the investigation of oil palm empty fruit bunch (EFB) fiber-supported heterogeneous acid catalyst that was prepared via direct impregnation method by using various types of transition metal sulfates, including Fe2(SO4)3, NiSO4.6H2O, and CuSO4. The EFB fiber-supported heterogeneous acid catalyst was applied for esterification of oleic acid. Hence, structural, chemical, morphological, and elemental properties of the catalyst were examined through the use of X-ray diffraction (XRD), Fourier transform infrared (FTIR), scanning electron microscope (SEM), and electron dispersive X-ray spectroscopy (EDX) analyses. Meanwhile, the acidity properties of each catalyst were characterized via acid density test. The prepared catalyst, which had been loaded with Fe2(SO4)3, exhibited the highest acid density up to 2.4 mmol/g. Next, the catalytic activity of the heterogeneous acid catalyst was further investigated through esterification of oleic acid at 60°C with 5 wt% catalyst loading for 2 hours of reaction time. The prepared catalyst, which was loaded with Fe2(SO4)3, again displayed the high esterification conversion rate at 93.90% and was used up to five reaction cycles.
