新疆三塘湖盆地侏罗系煤有机地球化学特征

有机地球化学和有机岩石学研究结果表明，新疆三塘湖盆地侏罗系煤中富集孢子体和角质体（３．０％～６．０％，全岩体积百分比），对煤中氯仿沥青“Ａ”组成中较高的总烃馏分（３０％～５０％）和饱芳比（０．６～３．０）产生了影响。煤的聚集环境是影响煤的显微组分组成及生油特性的关键因素。三塘湖盆地侏罗系煤属于“晚生晚排”叠加有“早生早排”类型的烃源岩。

Final Drying of Whole Milk Powder in Vibrated-Fluidized Beds

Vibro-fluidized beds are widely used in drying sticky powders and agglomerated materials as milk powder. Using a vibro-fluidized laboratory scale dryer, this work is aiming at analyzing preliminarily the effect of its operational variables on the drying kinetics and characteristics of whole milk powder. The full-factorial design technique with three replications at the central point has been employed to generate data and correlations to quantify the effect of inlet air temperature, air flow rate, and vibration bed amplitude on the drying curves and the milk powder properties related to its faster reconstitution in water (as tapped density, Hausner cohesion ratio, agglomerate size distribution, and internal pore concentration). Results obtained are analyzed and discussed to identify the adequate operation condition for final drying whole milk powder in vibro-fluidized beds, assuring a high product quality.

Apparent versus true density for the volume-to-weight transformation in coal blends

This work reviews the procedures involved in the conversion of the petrographic characterization data of blended coals into weight percentages of the single coals in the blends, the selection of the most suitable parameter for describing the density of the coals being critical. First, the fundamentals of the volume-to-weight transformation of the petrographic data were developed by means of mathematical formulae. This part of the procedure highlighted the need to use a density value adapted to the resolving power of the optical microscope. It was found that mercury penetration at 5 MPa, as determined by mercury porosimetry, was best suited for this purpose. A literature survey of published coal density data revealed that the use of correlations between coal density and rank was not an accurate enough procedure to deal with the relatively low corrections involved in the transformation of petrographic data. In the end, three binary blends were prepared from six carefully selected coals and polished particulate blocks of these blends were petrographically analysed to determine their compositions on a volume per cent basis. The best fit of these volume percentages with the weight percentages used in the formulation of the blends was found for a density correction based on mercury penetration at 5 MPa, in agreement with the empirical analysis.
