Effect of chemical refining steps on the minor and major components of cottonseed oil

During chemical refining steps (neutralization, bleaching and deodorization) of crude cottonseed oil (CSO), minor and major components, namely, tocopherols, sterols and fatty acids were evaluated by HPLC and GLC. HPLC analysis of total tocopherols (T) revealed that loss in these components were 7.12, 12.28 and 18.47 % in neutralized, bleached and deodorized oil respectively. On the other side, ...

Determining Oil Content of Cottonseed

Engine Performance Test of Cottonseed Oil Biodiesel

Two cottonseed oil biodiesel samples (cottonseed oil methyl esters, COME) produced in Clemson lab, together with other two commercial cottonseed oil biodiesels were evaluated on their engine performance with the No. 2 diesel fuel as a reference. The results revealed that emission of CO, CO2 and NOx from cottonseed oil biodiesels was lower than that of the No. 2 diesel fuel. CO decreased by 13.8...

Performance of Sudanese Activated Bentonite in Bleaching Cottonseed Oil

Bentonite clay collected from Jabal Umm Ali area NE of Khartoum (Sudan) was characterized by X-ray diffraction (XRD). It was then purified by treatment with distilled water and activated with sulfuric acid at 90 oC for 3.5 hrs. XRD indicated modification of activated bentonite with enhanced surface area. Several cations were removed from octahedral sheet (Mg, Al, and Fe). Increasing the acid co...

Engine Performance and Exhaust Emissions of Cottonseed Oil Biodiesel

The objective of this research was to determine the relationship between engine performance and emissions of cottonseed oil biodiesel used in a 14.2 kW diesel engine. When using cottonseed oil biodiesel blends, CO, total hydrocarbon (THC), NOx, and SO2 emissions decreased as compared to petroleum diesel. Carbon dioxide emissions had no definitive trend in relation to cottonseed oil biodiesel bl...
