CATALYTIC CRACKING OF HEAVY NAPHTHA USING NEW SULPHONATED MICA CATALYST [PDF]
Journal of Environmental Science, 2019 Sulphonated mica was prepared as catalytic cracking catalyst for heavy naphtha by sulphonation of oxidized mica using sulfuric acid. The oxidized mica was prepared by the treatment of mica with nitric acid to obtain its oxidized form. The raw mica and the prepared catalyst were analyzed by X-ray diffraction and FT-IR spectral analysis.
