4.The percentage of free fatty acid(FFA) in cottonseed oil deodorizer distillate(CODD)is 40%~80%.
5.Although the technology of supercritical carbon dioxide (in short as ‘SC-CO2’) has been widely applied to extract and concentrate natural vitamin E from DOD, and many achievements have also been reported, there are some drawbacks such as the absence of phase equilibrium for pretreatment of DOD/CO2 system.
6.Diamantane compounds were detected out from saturated hydrocarbon fractions of chloroform bitumen A and C of carbonate source rock samples from three wells (Shancan 1, Shan 42 and Shan 17) in O 1m 5 sections of the central gas field of Ordos basin.
