INVESTIGATION OF CATALYTIC ACTIVITY OF HYDRIDES IN THE DESULFURIZATION REACTIONS OF LIQUID-HYDROCARBON FUELS

The sulphur content of liquid hydrocarbon fuels is an important index if their quality. The hydrides of Ni-Zr alloys are prospective catalys ts for oil-product hydrodesulphurisation. They allow a higher degree o f fuel purification from sulphur and they increase the equipment produ ctivity. Test samples of the catalysts capsulate contacts are received and a method is developed for this process. Their catalytic activity both using the trample of the demercaptanization reaction and the extr action of total sulphur from the kerosene fraction is studied. The pro cesses occurring on Ni-Zr alloys due to the interaction with hydrogen are investigated by electron microscopy.
