In the microreactor, the 1,2-dichlorethane selectivities of 4.7% and 53.6% were achieved with the ethene conversions of 1.6% and 6.4%, respectively. The other important product was chloroethane. The formation of vinyl chloride by-product of 1.6% was observed only at the highest temperature 250 °C with highest ethene conversion achieved (6.4%). No other by-products were observed. In the millireactor, the 1,2-dichlorethane selectivities exceeding 96% were achieved at ethene conversions higher than 11% within the entire experimental range. Chloroethane, vinyl chloride, 1,2-dichloroethylene (trans) were formed, but only in minor amounts.

Co3O4 Supported on Different Supports for N2O Decomposition.
Klyushina, A. ; Pacultová, K. ; Jirátová, Květa ; Obalová, L.
In this work Co3O4 catalysts supported on different kind of shaped supports (rings, quadrulobes) were prepared by incipient wetness impregnation method. As support materials commercial supports made of MgAl oxides, Al2O3 and TiO2 were used. The catalysts were characterized by AAS, XRD, Raman, FTIR, SEM, H2-TPR and nitrogen adsorption methods and tested for nitrous oxide decomposition.
