| abstract |
The present invention relates to a catalyst comprising a support having at least one series of channels whose opening is defined by a ring comprising 12 oxygen atoms and comprising at least one zeolite and at least one binder, At least one C1-C4 dialkyl succinate, acetic acid, and a hydrodehydrogenating functional group comprising at least one element of group VIB and at least one element of group VIII. Raman spectrum of the catalyst is at least one heteropoly anion kegin distinctive 990 and / or 974 cm - comprises a band, the specific succinates of the band and a main band at 896 cm -1 characteristic acid in the first. The present invention also relates to a catalyst preparation process and the use of said catalyst in hydrogen conversion. |
