Abstract

The invention relates to catalysts for producing synthesis gas by steam conversion of hydrocarbons, in particular methane. The aim of said invention is to increase the time of steady operation of a catalyst having a high activity and improve the degree of utilisation of an active component . The inventive catalyst comprises nickel and lanthanum oxides applied to an aluminium-magnesium oxide carrier, in addition to zirconium dioxide at the following ratio between components, expressed in mass %: nickel oxide 3.7-16.0 lanthanum oxide 0.1-4.1 zirconium dioxide 0.1-2.2 the rest being aluminium carrier. The aluminium carrier is embodied in the form of a trifolium provided with three cylindrical holes having an equal wall thickness on the cross-section. The inventive method consists in producing synthesis gas by steam conversion of hydrocarbons at a temperature ranging from 750 to 950 °C in the presence of said catalyst.
