“…The word kapok is used to refer fiber and seeds. Kapok fiber has the characteristics of a large lumen and the hydrophobic-oleophilic so suitable for use as (i) an absorbent to remove methylene blue from aqueous solution (Shim et al 2013), (ii) absorption of the oil and separator filter of oil with water Abdullah et al 2010;Wang et al 2012), (iii) removal of hazardous material because it has a uniform morphology (Hwang et al 2013). Waste of kapok seed husks could be used as activated carbon to remove copper, cadmium (Rao et al 2006) and lead, zinc (Rao et al 2008) in aqueous solution.…”

Availability of fossil fuels in the world decrease gradually due to excessive fuel exploitation. This situations push researcher to look for alternative fuels as a source of renewable energy, one of them is kapok (ceiba pentandra) seed oil. The aim this study was to know the behavior of laminar burning velocity, secondary Bunsen flame with open tip, cellular and triple flame. Premixed combustion of kapok seed oil was studied experimentally on perforated burner with equivalence ratio (φ) varied from 0.30 until 1.07. The results showed that combustion of glycerol requires a large amount of air so that laminar burning velocity (SL) is the highest at very lean mixture (φ =0.36) in the form of individual Bunsen flame on each of the perforated plate hole. Perforated and secondary Bunsen flame both reached maximum SL similar with that of ethanol and higher than that of hexadecane. Slight increase of φ decreases drastically SL of perforated and secondary Bunsen flame. When the mixture was enriched, secondary Bunsen and perforated flame disappears, and then the flame becomes Bunsen flame with open tip and triple flame (φ = 0.62 to 1.07). Flame was getting stable until the mixture above the stoichiometry. Being isolated from ambient air, the SL of perforated flame, as well as secondary Bunsen flame, becomes equal with non-isolated flame. This shows the decreasing trend of laminar burning velocity while φ is increasing. When the mixture was enriched island (φ = 0.44 to 0.48) and petal (φ = 0.53 to 0.62) cellular flame take place. Flame becomes more unstable when the mixture was changed toward stoichiometry.

“…There are several factors used in determining the physical characteristics of oil sorbent material such as structure of fiber, moisture content, material strength, color, sorption and buoyancy. [12], c [13], d [14], e [15] The kapok fiber has a smooth surface with hollow microstructure (or lumen) as shown in the SEM images in Fig. 2(a) while rayon fiber and polypropylene has a rough surface without internal structure as shown in the SEM image in Fig.…”

Abstract-The aim of this study was to investigate the utilization of a recycled rayon waste-kapok mixtures as an oil sorbent for the removal of diesel, motor oil and bunker C. The effects of the kapok fibers: rayon fibers ratio and the additional of sodium sulfate on RRWK sorbents properties were investigated through series of oil sorption tests. The ASTM 726-06 method was used to determine the oil sorption capacity of the sorbents under both static and dynamic conditions. The results showed the high sorption capacity of the recycled rayon waste-kapok mixture for difference kinds of oil. Oil, which has a high viscosity, tends to have a higher oil sorption ratio. RRWK sorbents had higher oil sorption capacity than commercial polypropylene. The presence of kapok fibers in RRWK increases the hydrophobicity and oil sorption capacity of the sorbents while the presence of rayon fibers improves the strength of the sorbents. The additional of sodium sulfate during sorbent preparation increases the surface area and pore size of RRWK sorbent and thus improves the oil sorption capacity. It can be concluded that RRWK, which can be produced by utilizing industrial waste, is effective low cost, environmentally friendly oil sorbent with comparable performance to commercial products.

“…However, the unregulated application of oil has led to serious pollution and environmental problems, which in turn cause great harm to human health. The severity of the oil pollution problem coincides with the expansion of oil exploration and production activities, as well as industrial growth around the world (Abdullah et al 2010). Oil pollution is one of the foremost environmental issues facing the public today (Ibrahim et al 2010).…”
