“…A large amount of toxic materials are present and they are oxidised in the DPF, and that's why DPF vehicles show more dithiothreitol-redox activity per mass of emitted soluble organic fraction (SOF), but show a lower oxidation rate per kilometre. Vojtisek-Lom et al [59,60] has also used RME and commercial diesel fuel. A lubricating ester based oil that has been derived from plants (Fuchs oil) was used to reduce the effect of engine lubricating oil on the PAH emission.…”

“…Trung bình hơn 95 % lưu huỳnh trong nhiên liệu được chuyển thành SO2, khoảng 1-5 % là tiếp tục bị ôxi hóa thành sulfur trioxide (SO3) và 1 -3 % được phát ra như hạt sulfate. SO3 dễ dàng phản ứng với hơi nước (cả ở ngoài không khí và trong khí thải) để tạo thành acid sulfuric [28]. Sau khi được hình thành, phần lớn khí SO2 sẽ thoát ra ngoài cùng với khí thải, nhưng có thể một phần lọt vào trong ngăn chứa dầu, khi nhiệt độ trong ngăn chứa xuống thấp SO2 sẽ kết hợp với hơi nước để tạo các acid tương ứng gây ăn mòn các bề mặt chi tiết khi dầu được bơm trở lại các bề mặt bôi trơn.…”

This study evaluated brake specific fuel consumption and regulated emissions from palm biodiesel fuel (palm BDF) used on diesel generators. The tests were performed at an idle and high load with different mixing rate blends between diesel fuel and palm BDF (0 %, 5 %, 10 %, 15 %, 20 %, 50 %, 100 % which was called B0, B5, B10, B15, B20, B50 and B100) respectively. The results showed at each loading mode, brake specific fuel consumption increased when the volume of palm BDF rose in the blends. At the idle mode, brake specific fuel consumption increased 1.32 %, 1.8 %, 2.8 %, 3.74 %, 5.61 %, 6.54 % for B5, B10, B15, B20, B50, B100, compared with B0. Similarly at the high load mode, brake specific fuel consumption improved 1.51 %, 1.86 %, 2.18 %, 4.78 %, 5.36 %, 6.76 % for B5, B10, B15, B20, B50, B100, compared with B0. In both two load modes, when the volume of palm BDF in the fuel blends grew gradually, the concentration of CO, SO2 and CxHy emission reduced while the concentration of NO and NO2, CO2 went up. Emission factors of CO, SO2 and CO2 at high load are higher than those at an idle load, regardless the ratio of palm BDF to diesel fue. Conversely, emission factors of NO, NO2 at high load are higher.

“…Controlling PAH emission from combustion sources is one of the most effective measures for the protection of the environment and human health (Ravindra et al 2008;Xu et al 2005). Many studies have focused on PAH emission from mobile and domestic sources (Chen et al 2013;Huang et al 2014;Lu et al 2012;Shen et al 2011;Vojtisek-Lom et al 2012), but there are limited data on stationary sources, especially on emissions from stack gases of industrial processes. Generally, the quantities and characteristics of PAHs emitted from industrial processes may vary widely, depending on the type of input (fuel, additive, and others), manufacturing process, air pollution control devices (APCDs), and others (Li et al 1999;Manoli et al 2004).…”

Field monitoring was conducted to develop a polycyclic aromatic hydrocarbon (PAH) emission inventory for the magnesium (Mg) metallurgy industry in China. PAH emissions in stack gas and fly/bottom ash samples from different smelting units of a typical Mg smelter were measured and compared. Large variations of concentrations, congener patterns, and emission factors of PAHs during the oxidation and reduction stages in the Mg smelter were observed. The measured average emission factor (166,487 μg/t Mg) was significantly higher than those of other industrial sources. Annual emission from Mg metallurgy in 2012 in China was estimated at 116 kg (514 g BaPeq) for PAHs. The results of this study suggest that PAH emission from Mg industries should be considered by local government agencies. These data may be helpful for understanding PAH levels produced by the Mg industry and in developing a PAH inventory.
