Waste cooking oil (WCO) was used as a potential feedstock for biodiesel production. High levels of free fatty acids (9.85% w/w) in WCO made it an undesirable substrate for direct transesterification reaction. To solve this issue, a two-step process was implemented in this research. Firstly, esterification reaction was performed in presence of sulfuric acid as a common acid catalyst to reduce th...

Summary The publication outcomes of the abstracts presented during the ECCEO-IOF 2011 reflect a high research productivity, support the robustness of the selection process conducted by the Scientific Advisory Committee and suggest that IOF-ESCEO WCO is successful in its mission to promote and disseminate research. Background and Objective The European (now World) Congress on Osteoporosis, Osteo...

We have carried out high-resolution (∼3′) HI and CO line observations along onedimensional cuts through the Galactic worm GW46.4+5.5. By comparing the HI data with IRAS data, we have derived the distributions of I100 excess and τ100 excess, which are respectively the 100 μm intensity and 100 μm optical depth in excess of what would be expected from HI emission. In two observed regions, we were ...

In recent years, Reclaimed Asphalt Pavement (RAP) has become very popular in pavement construction due to its benefits the economy and environment. The present study investigates feasibility of employing Waste Cooking Oil (WCO) Engine (WEO) as rejuvenators blended with reusable asphalt binder through physical rheological properties at high intermediate temperatures. Examined conventional WCO-an...

Abstract Waste cooking oil (WCO) is a promising feedstock for producing biodiesel, which plays significant role in waste resource reusing and renewable energy production. It known that cost the main factor restricting large-scale production of biodiesel. Therefore, Life Cycle Cost (LCC) method was used to analyze economic feasibility biodiesel process from WCO. Our results show 1 ?t WCO 6291.56...

The rising demand for non-renewable resources such as asphalt binder is a significant issue in the pavement industry. Flexible consumes amount of binder, which has become major terms environmental sustainability and from an economics viewpoint. Hence, researchers strive to find other alternatives solve these problems, enhance performance lifespan flexible pavement. Biomass-based bio-oil, waste ...

Abstract Fatty acid methyl esters (FAMEs) are sustainable biofuel that can alleviate high oil costs and environmental impacts of petroleum-based fuel. A modified 1200 W high-efficiency food blender was employed for continuous transesterification various refined vegetable oils waste cooking (WCO) using sodium hydroxide as a homogeneous catalyst. The following factors have been investigated on th...

Waste cooking oil (WCO) is that has been used for frying more than three times, so it classified as dangerous which can endanger human health and also have a negative impact on the environment. The city of Denpasar every month produces approximately 604,629 liters/month waste until now not clearly managed. WCO if managed properly will be potential, because processed into products provide added ...

We present a theoretical model for Type Ib supernova (SN) 2006jc. We calculate the evolution of the progenitor star, hydrodynamics and nucleosynthesis of the SN explosion, and the SN bolometric light curve (LC). The synthetic bolometric LC is compared with the observed bolometric LC constructed by integrating the UV, optical, near-infrared (NIR), and mid-infrared (MIR) fluxes. The progenitor is...
