PROCESS FOR HYDROGENATION OF WAX AND PROCESS FOR PRODUCTION OF FUEL BASE

摘要

PROCESS FOR HYDROGENATION OF WAX AND PROCESS FOR PRODUCTION OF FUEL BASE THE WAX HYDROTREATING PROCESS OF THE INVENTION IS A PROCESS COMPRISING A FIRST 5 STEP WHEREIN A WAX WITH A C16 OR GREATER NORMAL PARAFFIN CONTENT OF 70 RNASSOR GREATER IS USED AS THE STARTING MATERIAL AND THE WAX IS CONTACTED WITH A CATALYST IN THE PRESENCE OF HYDROGEN FOR HYDROCRACKING, THE CATALYST CONSISTING OF A METAL OF GROUP VIII OF THE PERIODIC TABLE SUPPORTED ON A CARRIER CONTAINING AN AMORPHOUS SOLID ACID, A SECOND STEP WHEREIN THE STARTING 0 MATERIAL IS TEMPORARILY SWITCHED FROM THE WAX TO A LIGHT PARAFFIN WITH A C9-21 PARAFFIN CONTENT OF 60 MASSOR GREATER, AND THE LIGHT PARAFFIN IS CONTACTED WITH THE CATALYST IN THE PRESENCE OF HYDROGEN FOR HYDROCRACKING, AND A THIRD STEP WHEREIN THE STARTING MATERIAL IS SWITCHED FROM THE LIGHT PARAFFIN TO THE WAX AND THE WAX IS CONTACTED WITH THE CATALYST IN THE PRESENCE OF HYDROGEN FOR 5 HYDROCRACKING.
