As crude oil price reach a new high, the need for developing alternate fuels has become acute. Alternate fuels should be economically attractive in order to compete with currently used fossil fuels. In this work, biodiesel (ethyl ester) was prepared from waste cooking oil collected from a local restaurant in Halifax, Nova Scotia, Canada. Ethyl alcohol with sodium hydroxide as a catalyst was use...

bioremediation, the process by which microorganisms degrade organic compounds to non-toxic or less toxic substances, has been widely used for cleanup of coastal ecosystems after oil spills. in this study, the hydrocarbon degradation rate and half lives in three bioremediation strategies (natural attenuation, biostimulation, and bioaugmentation) were compared in weathered crude oil (wco) contami...

Synthesis of the solid bifunctional vanadium-calcium mixed oxides catalyst was accomplished by application a simple physical mixing approach. In this work, we compared catalytic activity CaO and 2%V2O5.CaO catalyst. Various characterization methods, such as X-ray fluorescence (XRF), diffraction (XRD), Fourier transform infrared (FTIR), BET surface area, temperature-programmed desorption (TPD) C...

The catalytic performance of potassium hydroxide supported on alumina (KOH/Al2O3) for transesterification waste cooking oil (WCO) was investigated. XRD, FTIR, and SEM techniques were used to characterize the catalyst after it had been synthesized using wet impregnation method. properties WCO produced biodiesel evaluated. main fatty acids linoleic (45.61%), elaidic (33.86%), palmitic (10.32%), s...

The management of waste cooking oil (WCO) often poses significant challenges. improper disposal WCO results in negative environmental impacts and economic losses. However, from a circular economy perspective, can be recycled used as sustainable feedstock for numerous industrial products, replacing virgin vegetable oils. This approach enables the recovery resources while simultaneously addressin...

Pilot-fueling and nozzle-injection pressure are significant injection parameters, they have impacts on modern vehicles for enhancing the engine output, in addition to meeting rigorous tailpipe-exhaust emission standards. In this current work, influence of pilot-fueling nozzle-opening (NOP) performance tailpipe outcomes from a compression-ignition (CI) at higher varying load conditions was inves...

Microbial synthesis of wax esters (WE) from low-cost renewable and sustainable feedstocks is a promising path to achieve cost-effectiveness in biomanufacturing. WE are industrially high-value molecules, which widely used for applications chemical, pharmaceutical, food industries. Since the natural resources limited, production mostly rely on chemical rather expensive starting materials, therefo...

The recyclability of waste cooking oil (WCO) as rejuvenator for aged asphalt mixture improved the serviceability pavement itself. Currently, researcher is exploring new potential WCO modifier binder modification. However, issue compatibility properties in modification with arises since poor mechanical performance globally recorded thus reflected weakness adhesion bonding inside material. Basica...

The esterification of oleic acid was applied in order to screen the suitability a series phosphotungstic-based Wells-Dawson types compounds as potential catalysts heterogeneous transesterification sunflower waste cooking oil. This test reaction indicated that phosphotungstic heteropolyacid H6P2W18O62·xH2O, dispersed on titania oxide loading 15 mg per m2 support (named 42% HPA/TiO2) and possessi...
