Different from other options which usually required strict conditions, a method combining atmospheric oxidization and chemical cleaning with alkali solutions was employed to desulphur coals at temperature around 90°C. The data show that 66% organic sulphur, 44% sulphide sulphur, and 15% pyrite sulphur were lost when the coal was treated in 0.25M NaOH at 90°C, while the solution being aerated at the...
Similar to cigarette smoke, fumes from cooking oil contain lots of carcinogens such as aromatic amines, polycyclic aromatic hydrocarbons (PAHs), nitro-polycyclic aromatic hydrocarbons, etc. and are notoriously difficult to remove by traditional static method. In this paper, low temperature catalytic oxidation was employed to treat cooking oil fume. A novel catalyst, based on MnO 2 /CuO, was...
