The photocatalytic degradation of the commercial reactive Black5 (RB5), Blue19 (RB19), Green19 (RG19), Red120 (RR120), and Yellow81 (RY81) in aqueous solution and sunlight were examined in the presence of Fe2O3 and the mixture Fe2O3/H2O2 as catalysts. The results showed that the photocatalytic degradation followed first-order...

Catalytic distillation is a technology that combines heterogeneous catalytic reaction and the separation of reactants products via in single reactor/distillation system. This process catalysis, kinetics, mass transfer to obtain more selective products. The catalyst provides sites for reactions porous surface liquid/vapor separation. advantages are energy savings, low waste streams, longevity, h...

Control of temperature and duration of partial carbonization for Chinese medicines have been mainly based on experience of the processors. No quantitative methods and parameters are available that can be used to precisely control the temperature and determine the energy changes during the process. In our research, with a simulated atmosphere air condition, the partial carbonization processes of...

Low pressure dehydroxylation of serpentine phases is important in processes such as the inertialisation of chrysotile asbestos or the CO2 sequestration in ultramafic rocks. Although research on the mechanism of this process goes back to the forties of last century, the dehydroxylation mechanism is still not fully elucidated. In this study with used non-isothermal thermogravimetric (TGA) analyse...

“There is the employer’s sabotage as well as the worker’s sabotage. Employers interfere with the quality of production, they interfere with the quantity of production, they interfere with the supply as well as with the kind of goods for the purpose of increasing their profit. But this form of sabotage, capitalist sabotage, is antisocial, for the reason that it is aimed at the benefit of the few...

Due to the massive increase in polymer manufacture, there has been a remarkable plastic waste. With fewer landfills being used dump waste each year, it is becoming increasingly important use effective recycling methods for decomposition. In present work, polystyrene was degraded presence of natural clay (K<sub>0.02</sub>, Ca<sub>0.15</sub> [Mg<sub>0.25</sub>,...

The trunk of a knot in S3, defined by Makoto Ozawa, is a measure of geometric complexity similar to the bridge number or width of a knot. We prove that for any two knots K1 and K2, we have tr(K1#K2)= max{tr(K1), tr(K2)}, confirming a conjecture of Ozawa. Another conjecture of Ozawa asserts that any width-minimizing embedding of a knot K also minimizes the trunk of K. We produce several families...

The global net emissions of the Kyoto Protocol greenhouse gases (GHG), such as carbon dioxide (CO2), fluorinated gases, methane (CH4), and nitrous oxide (N2O), remain substantially high, despite concerted efforts to reduce them. Thermal treatment solid waste contributes at least 2.8–4% GHG in part due increased generation municipal (MSW) inefficient processes, incineration landfill. gasificatio...
