Reforming catalyst and a method of modification and application thereof

A process for preparing a reforming catalyst, the process consisting of:

• first, impregnating at least one support with at least one promoter metal and at least one active metallic component to obtain a second catalytic precursor;
• second, contacting the second catalytic precursor with aqueous HCl to obtain a third catalytic precursor;
• third, coating the third catalytic precursor with tetraethyl orthosilicate at a temperature in a range of 20-35° C. to obtain a coated third catalytic precursor, wherein coating with tetraethyl orthosilicate improves an acidic character of the at least one support and improves a sinter resistance behavior of the at least one active metallic component;
• and
• fourth, drying the coated third catalytic precursor to obtain a dried third catalytic precursor followed by calcination of the dried third catalytic precursor for a time period in a range of 3-7 hours at a temperature in a range of 400-600° C. to obtain the reforming catalyst.
