Processes for converting linear hydrocarbon into normal alpha olefins ("NAOs"). The process comprises a sequence of controlled dehydrogenation followed by ethenolysis. The process is especially applicable to upgrade linear hydrocarbons such as produced by Fischer-Tropsch type processes. A process for converting C1-C3 alkanes into NAOs and an integrated process including hydrocracking are also disclosed. L'invention concerne des procédés de conversion d'hydrocarbures linéaires en alpha oléfines normales (NAOs). Le procédé consiste en une séquence de déshydrogénation régulée suivie d'éthénolyse. Le procédé s'applique en particulier pour améliorer des hydrocarbures linéaires tels que ceux produits suivant les synthèses du type Fischer-Tropsch. L'invention concerne également un procédé de conversion de C1-C3 alcanes en NAOs, ainsi qu'un procédé intégré comportant l'hydrocraquage.
