The depletion of fossil fuels has heightened research and utilization renewable energy such as biodiesel. However, this thrown up another challenge significant increase in its byproduct, glycerol. In view the characteristics potentials glycerol, efforts are on to convert it higher-value products, which will turn improve overall economics biodiesel production. These high-value products include biofuels, oxygenated fuel additives, polymer precursors other industrial bio-based chemicals. This...
A biomass derived carbon supported yttrium oxide catalyst (Y2O3/PKS-T700) was synthesized and evaluated in glycerol acetylation reaction using four-factor, two-level face-centred central composite design (24 CCD) of the response surface methodology (RSM). The exhibited high conversion (GC) (99.8%) product selectivity 11.1%, 60.2%, 29.6% monoacetin (MA), diacetin (DA) triacetin (TA) under optimized conditions temperature 130 ℃, glycerol-to-acetic acid molar ratio 1:12 loading 0.5 g 5 h time....
In this study, an optimized mesoporous sulfonated carbon (OMSC) catalyst derived from palm kernel shell biomass was developed using template carbonization and subsequent sulfonation under different temperatures time conditions. The OMSC characterized acid-base titration, elemental analysis, XRD, Raman, FTIR, XPS, TPD-NH3, TGA-DTA, SEM, N2 adsorption–desorption analysis to reveal its properties. Results proved that the is amorphous in structure with improved textural, acidic, thermal Both...
Biodiesel was produced via transesterification of palm oil with methanol in the presence CaO-Nb 2 O 5 mixed oxide catalyst.Response surface methodology (RSM) central composite design (CCD) performed to determine optimum operating conditions and optimize biodiesel yield.In this study, reaction variables being optimized were time, catalyst loading molar ratio.From analysis variance (ANOVA), most influential parameter on production time.The predicted yield found good agreement experimental...
In this work, to fabricate a novel composite consisting of chitosan/poly-lactic acid doped with graphene oxide (CS/PLA-GO), composites were prepared via solution blending method create various compositions CS and PLA (90/10, 70/30 50/50CS/PLA-GO). Graphene (GO) was added into prior it chitosan (CS). The surface morphology structural properties synthesized characterized using FT-IR, SEM XRD analysis. performances on thermal strength, mechanical water absorption, microbial activity also...
Hybrid natural fiber polymer nanocomposites were prepared using various fibers (kenaf, coir, and wood), polypropylene, montmorillonite nanoclay through the hot compression method. The effects of hybridization content on physico-mechanical biodegradable properties synthesized composites investigated. Fourier-transform infrared scanning electron microscopic analyses indicated that structure surface morphology transformed after subsequent incorporation. X-ray diffraction pattern revealed...
Hydrogenolysis of biomass-derived glycerol is an alternative route to produce 1,2-propanediol. A series transition metals supported on dolomite catalysts (Cu/Dol, Ni/Dol, Co/Dol, Fe/Dol, Zn/Dol) were prepared via impregnation, calcined at 500 °C and reduced 600 °C. The synthesized then characterized by BET, BJH, XRD, H2-TPR, NH3–TPD, SEM, subsequently evaluated in hydrogenolysis reaction 1,2-propanediol (1,2-PDO). nature was found influence the activation catalysts. Among tested catalysts,...
This present study examines the efficacy of using dolomite (Dol, CaMg(CO3)2)-supported copper (Cu) and cobalt (Co) bimetallic monometallic catalysts for hydrogenolysis glycerol to propylene glycol (PG; 1,2-PDO). The proposed were generated impregnation process before they calcined at 500°C reduced 600°C. Advanced analytical techniques namely Brunauer, Emmett, Teller (BET) method; Barrett, Joyner, Halenda (BJH) temperature-programmed desorption ammonia (NH3–TPD), hydrogen-temperature...
In this work, several copper supported catalysts, Cu/Dol, Cu/Al2O3, Cu/Bent, Cu/Mont, and Cu/Talc were prepared using wet impregnation route characterized BET, BJH, XRD, H2-TPR, NH3–TPD, SEM analytical techniques subsequently tested in hydrogenolysis of glycerol to 1,2-propanediol (1,2-PDO). The nature support was found determine the activation catalysts. Among dolomite catalyst (Cu/Dol) exhibited superior performance due species mutual interaction. findings from various characterization...
