Особливості кінетики окиснення етану на складних кобальт-нікель-фосфатних каталітичних системах

Abstract

The effect of the catalyst composition on the partial ethane oxidation has been studied. Experimental samples of the binary systems based on cobalt(II) and nickel(II) phosphates have been tested. A new approach to the preparation of cobalt-nickel-phosphate systems has been introduced, which is beneficial from the viewpoints of high stability, activity and selectivity towards the partial ethane oxidation into ethylene. Catalytic properties of the phosphate systems have been studied as a function of various parameters of the ethane conversion, namely, the catalyst composition, the thickness of the catalyst layer, temperature, contact time, ethane and oxygen concentration. An active and highly selective composite cobalt-nickel-phosphate catalyst for the ethane conversion into the ethylene has been developed.
