  • Publication number: 20240226868
    Abstract: The present invention relates to a catalyst for aromatization of alkanes having 4 to 7 carbon atoms, especially alkanes having carbon atoms. Said catalyst has the efficacy in the aromatics production with high conversion and high selectivity of aromatics or high yield of aromatics, wherein said catalyst comprises 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. Said catalyst is treated and dried with a microwave at a power in a range from 400 to 1,000 watts after step of contacting with a solution comprising at least 1 transition metal salt from group VIII transition metal and after step of contacting with a solution comprising at least 1 group IIIA metal salt.
