摘要: On a etudie, une pression totale de 101,3 kPa et en presence vapeur d'eau (P H2 O = 32 kPa), l'impact roches minerales carrieres norvegiennes suedoises, sur les rendements produits gazeux selectivites generees au cours la pyrolyse catalytique du n-heptane n-C7 H 6 2,9-4,7 kPa) dans gamme temperatures intermediaires 973-1073 K un GHSV 1200-1400 h -1 . Les resultats indiquent que le choix particules calcinees comme materiau lit influence distribution des alcenes. En particulier, dolomites [CaMg(O) 2 ] suppriment l'evolution d'especes d'hydrocarbures aromatiques non satures; toutefois, formation d'ethylene (C 4 ) ete correlee. propose egalement mecanisme Langmuir-Hinshelwood pour decrire l'equation vitesse phase dolomite calcinee 973 K.
