In this study, coconut oils have been transesterified with ethanol using microwave technology. The product obtained (biodiesel and FAEE) was then fractional distillated under vacuum to collect bio-kerosene or bio-jet fuel, which is a renewable fuel operate gas turbine engine. This process modeled RSM ANN for optimization purposes. developed models were proved be reliable accurate through different statistical tests the results showed that modeling better than RSM. Based on optimum production...
Malaysian Dolomite has shown potential deoxygenation catalyst due to high capacity in removing oxygen compound and produce quality of biofuel with desirable lighter hydrocarbon (C8-C24). The performance this was compared several commercial catalysts catalytic pyrolysis Waste Cooking Oil. Calcination at 900 °C N2 produced very activity decomposition CaMg(CO3)2 phase formation MgO-CaO phase. liquid product showed similar chemical composition the range gasoline, kerosene diesel fuel....
In this study, Malaysian dolomites as secondary catalysts are placed at the downstream of fluidized-bed gasifier. Three types with different elemental ratios CaO-MgO content denoted P1, P2, and P3 investigated EFB gasification reaction cracking temperatures (700–900 °C). The performance a variation catalyst to biomass weight ratio (C/B) (0.05 0.30 w/w) is evaluated. findings showed that total gas yield increased by 20%, hydrogen 66%, along an almost 99% reduction in tar P1 following...
Aluminium dross, a waste material produced by dissolution of aluminum scrap, was characterized physically and chemically various analysis techniques for potential to be used as catalyst. Using catalyst from materials reduced the cost synthesizing new An efficient derived industrial solid modified acid washing using in pyrolysis cooking oil. The modification dross resulted increased surface area (from 0.96 68.24 m2/g), acidity 315 748 µmol/g) thermal stability. Pyrolysis oil test performance...
Chemical and physical analysis was performed to identify the molten slag composition its ability be used as alternative catalyst in pyrolysis of waste cooking oil. The implementation such type catalytic material could useful reducing process cost. To increase efficiency (increase active site) slag, it modified by acid washing that resulted an acidity from 159 1224 µmol/g. results showed yield bio-fuel increased product selective n-C15 upon modification treatment.

Lipase-catalyzed production of palm esters was performed via alcoholysis oil and oleyl alcohol in solvent solvent-free systems using a 2 L stirred tank reactor (STR). Two immobilized lipases were tested Lipozyme RM IM exhibited superior performance both reaction systems. Reusability studies the enzymes system also demonstrated high stability as shown by its ability to yield more than 70% with up 19 cycles reusing same enzymes. Modification enzyme washing process improved TL maintaining 65%...
Malaysian Dolomite with 5% dispersion of nickel has shown potential deoxygenation catalyst due to high capacity in removing oxygen compound and produce quality biofuel desirable lighter hydrocarbon (C8−C24). The modified dolomite showed enhanced physicochemical properties by surface area increment average pore diameters reduction. performance this was compared two commercial catalysts catalytic pyrolysis Waste Cooking Oil. liquid product similar chemical composition the range gasoline,...

Characteristics and performance study of chicken eggshell metal-doped catalysts (Ni Cu) in the in-situ co-pyrolysis Empty Fruit Bunches (EFB) High-Density Polyethylene (HDPE), while commercial HZSM-5 served as a comparative benchmark. Ni-CES was synthesised through liquid-liquid co-precipitation method. All were compared based on surface area (BET), particle size (PSA), X-ray diffraction (XRD), Scanning Electron Microscopy (SEM) analyses. BET PSA revealed that possessed better...
The dependence of the world on fossil fuels has contributed to many environmental issues and energy shortages leading increase awareness discovering new technologies taking advantage excess plastic waste which in turn harms environment if improperly managed. One best is thermal technology specifically co-pyrolysis where products are generated form oil, gas char. disadvantages produced oil high content oxygenated compounds have negative impacts fuel characteristics addition low yield oil. To...
Scandia-stabilized zirconia (ScSZ) has 1.5–3 times superior conductivity owing to its crystal structure as compared yttria stabilized (YSZ). However, also due this, ScSZ experienced phase transition which affects stability when used an SOFC electrolyte material and anode. The typically ceria-doped 10mol%ScSZ (10Sc1CeSZ) Ce4+ - Ce3+ in reduced environment led lower fracture strength instability. Alternative promising co-dopants stabilised phase, such Nd, Sm Gd are identified a way forward...
