Hello, unfortunately  the eligibility criteria is that the candidate should have completed their graduation in either EEE/ECE/IE/Biomed .But you can try for other specializations in petroleum, rubber, polymer, food processing, Nanotechnolgy and material engineering after your BTech chemical engineering. You can check out the scope of chemical engineering using this link https://dqxeclau.top/courses/chemical-engineering-course

Best wishes.
