| description | FIELD: chemistry. ^ SUBSTANCE: present invention relates to oil refining, particularly to a method of preparing a bead platinum and zeolite-containing catalyst for cracking oil fractions. Described is a method of preparing the catalyst, involving mixing an aqueous suspension of zeolite Y with a suspension of alumina, sodium silicate solution with modulus-molar ratio SiO2/Na2O equal to 2.2-3.0, aluminium sulphate solution and chloroplatinic acid solution; moulding catalyst granules in a column with mineral oil; successive activation, first with a mixture of sodium sulphate and aluminium sulphate solutions with concentration of the latter equal to 0.1-4 g/dm3, then with aluminium sulphate solution with concentration of 4-10 g/dm3, and then with a solution of a mixture of nitrates of rare-earth elements; washing; drying and calcination of the granules in an atmosphere of flue gases and water vapour. ^ EFFECT: higher activity and apparent density of the catalyst. ^ 1 tbl, 4 ex
Настоящее изобретение относится к нефтепереработке, в частности к способу получения шарикового платиноцеолитсодержащего катализатора крекинга нефтяных фракций. Описан способ получения катализатора, включающий смешение водной суспензии цеолита Y с суспензией глинозема, раствором силиката натрия с модулем - мольным отношением SiO2/Na2O, равном 2,2-3,0, раствором сульфата алюминия и раствором платинохлористоводородной кислоты; формование гранул катализатора в колонне с минеральным маслом; последовательные активации сначала смесью растворов сульфата натрия и сульфата алюминия с концентрацией последнего 0,1-4 г/дм3, затем раствором сульфата алюминия с концентрацией 4-10 г/дм3, раствором смеси нитратов редкоземельных элементов; отмывку; сушку и прокаливание гранул в атмосфере дымовых газов и водяного пара. Технический эффект - повышение активности и насыпного веса катализатора. 1 табл. |
