Hematite (α-Fe2O3) has been proved to be a promising sorbent for mercury removal in various situations. The mercury removal performance of α-Fe2O3 was investigated using a simulated coal gasification syngas containing Hg0, N2, HCl, and/or H2S, a series of experiments were designed with HCl and H2S separately and both employed. For a better understanding in the interaction between HCl and H2S in mercury...
Series of adsorbents based on Al2O3 supported Cu and Mn have been prepared and tested for mercury removal from gas streams under various conditions. The metal content, impregnating sequence and the gas composition have significant effect on the performance of the adsorbents. Co-impregnation of Cu and Mn solutions is simple but also of help to improve the Hg pickup capacity, due to the synergic effect...
The production of microbial lipids by a batch or fed-batch culture of oleaginous yeast was compared using glucose and corncob hydrolysate as carbon sources. Batch cultures using 4%(w/w) glucose as the carbon source reached a dry biomass, lipid yields and cellular lipid content of 9.4g/l, 6.0g/l and 63.5%(w/w), respectively. However, batch cultures demonstrated that there was an inhibitory effect on...
The feasibility of biodiesel production from microalgae oil was investigated with respect to its fuel properties and blending characteristics with petroleum diesel. Microalgae oil methyl esters (MAMEs) showed satisfactory fuel properties, and their predominant components were 65.2wt.% methyl oleate and 18.5wt.% methyl linoleate. The MAMEs had a cold filter plugging point of −13°C, an iodine value...
The isomerization of endo-tetrahydrodicyclopentadiene (endo-THDCPD) to its exo-isomer (JP-10) has been investigated by using chloroaluminate ionic liquids (ILs) as catalysts. The catalyst activity and selectivity could be optimized by varying the mole fraction of AlCl 3 in the IL. Undesirable by-products derived from side-reactions such as skeletal rearrangement, alkylation, cracking, and...
