Equilibrium Moisture Characteristics of High Oleic Sunflower Seeds and Kernels

The equilibrium moisture content (EMC) characteristics of high oleic sunflower seeds and kernels between 10 and 55°C were determined by equilibrating the samples to known relative humidities (RH) above saturated salt solutions. EMC of the kernels was lower than that of seeds in the range of 11 to 96% ERH and at 25 and 40°C. Hysteresis effect was found for the EMC properties of seeds and kernels at 25°C. Four EMC-ERH models (modified Henderson, Chung-Pfost, Halsey, and Guggenheim-Anderson-de Boer) and their estimated parameters were evaluated for goodness of fit. GAB and Halsey equations showed the best fitting of experimental data although GAB equation adjusted for temperature described the EMC data the best. Components of the seed as oil content or hull/kernel ratio did not explain the slight differences in EMC found between the varieties.

Temperature and pressure effects on supercritical CO2 extraction of tomato seed oil

Tomato seed oil was extracted with supercritical carbon dioxide in a semibatch-flow extractor within the temperature range 313–343 K and the pressure range 10.8–24.5MPa. The extraction rates increased with pressure, but decreased with temperature increase because of the variation in solvent density and resultant differences in oil solubility. The fatty acid composition of the extracted oil was similar to that of soybean oil.     

焦化防砂室内实验研究

油井防砂工艺技术的研究与发展对疏松砂岩油藏的正常开采至关重要.焦化防砂是通过向地层内注入热空气使原油在高温下发生氧化裂解生成焦炭从而将地层砂固结的一种防砂新技术.为了对该项技术进行全面系统的理论分析与评价,设计并制作了一套焦化防砂实验装置,利用该装置进行了焦化防砂室内实验研究.焦化效果以岩样的抗压强度进行评价,实验结果表明,影响焦化后岩样抗压强度的主要因素为空气最高温度、处理时间和空气流量.此外,对焦化处理后的岩样所作的岩样组成分析揭示出,稠油胶结机理为氧化作用使部分油分和胶质变成沥青质,沥青质受到高度的缩合作用而成为高分子量的甲苯不溶物.由于新生胶质的氧化比原生胶质的氧化困难得多,因此适合焦化防砂的油层,其原油必须含有一定量的原生胶质和沥青质.

Application of Rachinger''s method to separate overlapped doublets in the X-ray photoelectron spectrum

Rachinger's method of separating ₁ and ₂ doublets in X-ray emission spectra is applied for the first time to separate the superimposed doublets due to spin-orbit coupling. This method has been applied to separate closely lying doublets such as (Ag 4p_3/2and Ag 4p_1/2, (Ni 3p_3/2and Ni 3p_1/2) and (Cu 3p_3/2and Cu 3p_1/2). The intensities ratios of the separated peaks are measured and compared with the ratios obtained from a first-order calculation. An excellent agreement between the measured and calculated ratios are obtained. Residual background intensities compared with the estimated values are found to agree within certain uncertainties.
