Publication number: 20170252726Abstract: The invention concerns a process for preparing a catalyst comprising at least one metal M from the platinum group, tin, a phosphorus promoter, a halogenated compound, a porous support and at least one promoter X1 selected from the group constituted by gallium, indium, thallium, arsenic, antimony and bismuth. The promoter or promoters X1 and the phosphorus are introduced during one or more sub-steps a1) or a2), the sub-step a1) corresponding to synthesis of the precursor of the main oxide and sub-step a2) corresponding to shaping the support. The tin is introduced during at least one of sub-steps a1) and a2). The product is dried and calcined before depositing at least one metal M from the platinum group. The ensemble is then dried in a stream of neutral gas or a stream of gas containing oxygen, and then is dried. The invention also concerns the use of a catalyst obtained by said process in catalytic reforming or aromatics production reactions.Type: ApplicationFiled: March 23, 2017Publication date: September 7, 2017Applicant: IFP Energies nouvellesInventors: Pricilla AVENIER, Sylvie LACOMBE, Herve CAUFFRIEZ
