Definitions
- Another preferred catalyst is a catalyst prepared by a process involving depositing a hydrogenation metal on an alumina or material containing alumina support, calcining said metal loaded support typically at between 350 to 500°C, preferably about 450 to 500°C for about 1 to 5 hrs, preferably about 1 to 3 hrs and fluoriding said metal loaded support using a high pH fluorine source solution to a bulk fluorine level of about 8 wt% or less (e.g., 2 to 8 wt%), preferably about 7 wt% or less, said high pH source solution being at a pH of 3.5 to 4.5 and preferably being a mixture of NH4F and HF followed by rapid drying/heating in a thin bed or rotary kiln to insure thorough even heating in air, oxygen containing atmosphere or an inert atmosphere to a temperature between about 350 to 450°C in about 3 hours or less, preferably 375 to 400°C and holding at the final temperature, if necessary, for a time sufficient to reduce
- catalysts prepared using solutions of pH 3.5 or less are not heated first, then it is preferred that they be subsequently activated at more severe conditions, i.e. for longer times and/or at higher temperatures. On the other hand, if they are heated first, then moderate activation procedures similar to those employed with catalysts made from the higher pH solution treatment will suffice.
- the sized material will range in size between about 1/64 to 1/32 inch in size.
- the total liquid product (TLP) from the isomerization unit can be advantageously treated in a second stage at mild conditions using the isomerization catalyst or simply noble Group VIII on refractory metal oxide catalyst to reduce PNA and other contaminants in the isomerate and thus yield an oil of improved daylight stability.
- the sample of Catalyst 2 as charged to the 3600 cc unit was activated as follows: at 300 psi H2 at 11 SCF H2/hour per pound of catalyst, heat from room temperature to 100°C at 10°C/hour; hold at 100°C for 24 hours; heat from 100°C to 250°C at 10°C per hour; hold at 250°C for 15 hours; then at 22 SCF H2/hour per pound of catalyst, heat from 250 to 400°C in 31 hours; hold at 400°C for 3 hours.
- Catalyst 5 was prepared by meshing the dried/heated form of Catalyst 5 to a particle size of 1/30" (14/35 mesh). After meshing to a particle size of 1/30" (14/35 mesh), Catalyst 6 was activated in flowing hydrogen by heating from room temperature to 100°C over a 2 hour period, holding at 100°C for 1 hour, heating from 100 to 450°C over a 3 hour period, holding at 450°C for 1 hour. Activation pressure was 50 PSI.
