The contents of n-paraffin and carbon number distribution in n-paraffin wax of diesel oil of Daqing oil field were determined by gas chromatography mass spectrometry: capillary column (30m×0.25mm×0.25µm) and FID. The optimal chromatographic conditions were as follows: FID temperature 31°C, column temperature beginning at 8°C, ending at 29°C, the increasing rate of temperature 5°C/min. Diesel oil 0#...
This paper studies the preparation technology of microencapsulation using cactus pectin and phospholipids. The result showed that the wall materials and their optimum composition was pectin/maltodextrin is 1∶2(mol/mol). the concentration of emulsion is 25%(wt/wt). The suitable proportion of core material and wall material was 0.5□1, homogenizing speed was 6000 r / min. The feed temperature of spray...
By modifying the SENKIN code of CHEMKIN chemical kinetics package, the combustion processes and the characteristics of hydrocarbon (HC) and carbon monoxide(CO) emissions of a HCCI engine were simulated. Furthermore, the formation of benzene (A1) and polycyclic aromatic hydrocarbons including naphthalene (A2), phenanthrene (A3), and pyrene (A4) in n-heptane HCCI combustion were analyzed. A multi-zone...
