Beschreibung
Zusammenfassung:	FIELD: chemistry; oil processing. SUBSTANCE: method involves mixing crude silica with aluminium hydroxide in mass proportion (1-2):1, and crude calcium aluminate in the amount of 25-45% of carrier mass plasticizing and lubricating with burning out additives mainly graphite and polyvinyl alcohol. The carrier is formed and processed in steam or steam condensate medium at 85-95 C during 2-4 h. The carrier is calcined at hibbenite BF AlCaOformation temperature preferentially at 1450-1550 C and impregnated with nickel and aluminium nitrate solution. The catalyst is dried and heat-treated. EFFECT: enhanced effectiveness of hydrocarbons steam conversion. 2 cl, 3 tbl Сущность изобретения: технический глинозем смешивают с гидроксидом алюминия в массовом соотношении 1 2 1, техническим алюминатом кальция в количестве 25 45% от массы носителя, пластифицирующей и смазывающей выгорающими добавками, предпочтительно графитом и поливиниловым спиртом, формуют носитель и обрабатывают в среде пара или парового конденсата при 85 95°С в течение 2 4 ч. Прокаливают носитель при температуре образования гиббонита БФ AlCaOпредпочтительно 1450 1550°С, и пропитывают растворами нитратов никеля и алюминия, сушат и термообрабатывают катализатор. 1 з. п. ф-лы, 3 табл.
