heal.abstract	At a total pressure of 101.3 kPa, and in the presence of water vapor (P-H2O = 32 kPa), the impact of commercially available Norwegian and Swedish quarried mineral rocks on the gaseous product yields and selectivities generated during the catalytic steam pyrolysis of n-heptane (Pn-C7H16 = 2.9-4.7 kPa) in the intermediate temperature range of 973-1073 K and GHSV 1200-4000 h(-1) was investigated. The results indicate that the choice of calcined mineral particles as the bed material influences the product distribution of alkenes. In particular, calcined dolomites [CaMg(O)(2)] suppressed the evolution of unsaturated and aromatic hydrocarbon species; however, the formation of ethylene (C2H4) was correlated. A Langmuir-Hinshelwood mechanism has also been proposed to describe the rate equation of the vapor-phase steam pyrolysis of n-heptane on calcined dolomite at 973 K.	en
