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...

Evaluation of Near Infrared Reflectance for Oil Content of Cottonseed

The status of ongoing research to use near infrared reflectance spectroscopy (NIRS) to measure cottonseed oil content is summarized. A data set of 36 seed samples consisting of a single replication of six entries grown at two locations for 3 yr was used to generate prediction equations for oil content of cottonseed (Gossypium hirsutum L.). The equations were generated with NIRS based on seed-oi...

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...
