Abstract

Experiments on the coking rates of variously prepared nickel catalysts on TiO2, Al2O3 and MgO in n-butane steam reforming show that changes in the relative coking rate at a rising steam excess in the gas phase depend mainly on the kind of support. The results obtained are accounted for by changes in the electron density at the site of nickel crystallite contact with the surface of various supports.

Abstract

Исследование скорости коксования никелевых катализаторов, приготовленных различным образом на TiO2, Al2O3 и MgO, в паровом крекинге н-бутана указывают на то, что изменения в относительной скорости коксования, при возрастающем избытке водяного пара в газовой фазе, зависят, в основном, от типа носителя. Полученные результаты приписывают изменениям электронной плотности на месте контакта никелевого кристаллита с поверхностью различных носителей.
