Catalyst for aromatization of alkanes having 4 to 7 carbon atoms, process of making, and process of aromatics preparation by using thereof

A catalyst for aromatization of alkanes having 4 to 7 carbon atoms comprising zeolite, at least 1 transition metal from group VIII transition metal in a range of 0.1 to 2% by weight based on the total weight of the catalyst, and at least 1 metal from group IIIA metal in a range of 0.1 to 5% by weight based on the total weight of the catalyst, wherein said catalyst is prepared from a process comprising:

• a) contacting a zeolite with a solution comprising at least 1 transition metal salt from group VIII transition metal to form a first mixture;
• b) treating and drying the first mixture obtained from step a) with a microwave at a power in a range from 400 to 1,000 watts to form a first dried mixture;
• c) contacting the first dried mixture obtained from step b) with a solution comprising at least 1 group IIIA metal salt to form a second mixture;
• d) treating and drying the second mixture obtained from step c) with a microwave at a power in a range from 400 to 1,000 watts to form a second dried mixture;
• and
• e) calcining the second dried mixture obtained from step d) at a temperature less than or equal to 650° C.
