Abstract

A catalyst is suggested for the synthesis of unsaturated hydrocarbons from carbon monoxide and hydrogen, containing oxides of iron and manganese. Sodium oxide is added in order to increase the catalyst activity. The component contents are as follows (expressed as mol.%):

Manganese oxide 6.0-29.6
Sodium oxide 1.7-3.1
Iron oxide the rest
Iron to manganese atomic ratio is (1.5 9):1

The catalyst is synthesized by precipitating of iron and magnesium hydroxides from nitrate solutions by an alkaline reagent, followed by the precipitate separation, washing, drying, calcination and reduction. The increase of the catalyst activity is achieved by using sodium carbonate as the alkaline reagent. The precipitation is carried out at pH=7.5-8.5.
