PERFECTIONNEMENTS RELATIFS A L'ISOMERISATION D'HYDROCARBURES PARAFFINIQUES

摘要

In the start up of a paraffin isomerisation process operating at 100 DEG -204 DEG C in the presence of HCL or a compound decomposable to it as activating agent, the catalyst bed is brought to at least 100 DEG C, preferably, at least 130 DEG C before the feedstock and activating agent contact the bed. Starting up the process in conventional manner at low temperature and gradually bringing the temperature up in the presence of feedstock and activating agent partially deactivates the catalyst.
