The catalytic cracking of <Emphasis Type=”Italic”>n-</Emphasis>heptane was carried out using HZSM-12 zeolite (Si/Al = 40). The materials obtained were characterized by X-ray diffraction (DRX), BET surface area and atomic absorption (AA). The catalytic tests were accomplished at 350, 400 and 450ºC in a fixed bed continuous flow reactor coupled o<Emphasis Type=”Italic”>n-</Emphasis>line to a gas chromatograph. The results showed that HZSM-12 was active in <Emphasis Type=”Italic”>n-</Emphasis>heptane catalytic cracking with the production of hydrocarbons in the range of C1 to C6 and an activation energy of 95.5 kJ mol<Superscript>-1</Superscript>.
