Catalysis of Ethylene Oxychlorination into 1,2-Dichlorethane in the Presence of CuCl2/CuCl Active Centres on the Surface of -Al2O3

The structure of CuCl2, CuCl catalyst active centres on the surface of γ-Al2O3 has been investigated on the basis of X-ray diffraction analysis. The influence of the catalyst structure on the mechanism of ethylene oxidative chlorination has been determined. Using mass spectroscopy the difference in the structure of active centers and the mechanism of the deposited and impregnated types of CuCl2, CuCl/γ-Al2O3 catalysts in the process of ethylene oxidative chlorination into 1,2-dichlorethane has been studied.

Interpretation of Salts Influence on the Regeneration Process of Rich Thioarsenate Solution by Oxidative Reduction Potential Measurement

In the article various contaminates of thioarsenate process of coke oven gas desulfurization were investigated by measuring oxidative-reduction potential (ORP). ORP measuring is a simple and indicative method of activity determination. The article has also explained the thiosulfate influence on the activity of scrubbing solution based on As3+/As5+ chemistry.
