Abstract

Mechanism of n-butane oxidation of α-VOPO4 has been studied in pulse fixed and vibrofluidized catalyst bed reactors by the pulse microcatalytic method. It has been established that the rates of catalysis and reduction are similar, which indicates a reduction-oxidation mechanism for butane conversion and maleic anhydride formation. In the course of catalysis the reaction products are formed largely at the expense of catalyst oxygen and α-VOPO4 reduces to (VO)2P2O7.

Abstract

Импульсным микрокаталитическим методом в установках проточного типа с неподвижным и вибровзвешенным слоем катализатора изучен механизм окисления н-бутана на α-VOPO4. Установлено равенство скоростей катализа и восстановления, свидетельствующее об окислтельно-восстаовительном механизме преврщения бутана и образования малеинового ангидрида. Показано, что в процессе катализа продкты реакции образуются, в основном, зт счет кислорда катализатора и происходит восстановление α-VOPO4 в (VO)2P2O7.
