In conversion of MethlyCycloPentane to
To enhance the activty of catalyst.
To Control the hyperactivity as dealing
with fresh or regenerated catalyst when
It Selectively poisions the active sites that
may degrade benzene formation.
Catalyst is arranged and air(O2) stripped
with inert gas.
Dehydrate the Catalyst.(200-250 ⁰F)
Now hydrogen with pressure and startup
oil is introduced and allow to soak the
catalyst.(250-400 ⁰F) at 50 ⁰F per Hr.
Injection of sulfur spike at 350-400 ⁰F.
When the temperature of the catalysts
bed is increased and maintained at 450 -
500ºF, the sulfur spike decomposes under
heat and catalytic action.
Hydrogen reacts with the sulfur spike
producing hydrogen sulfide (H2S). Some
methane gas is also released as the
sulfur spike decomposes.
The presulfiding will be terminated as
soon as the catalyst sulfided,this can be
know by measuring H2S in oulet stream.
Continuously measures H2S concentration
using dispersive UV-V’s absorbance
Totally solid state build with no moving
parts modern design for low maintenance
Easily multiplexed to analyze sample
streams from multiple sampling points
Decades of field-proven performance in
various catalytic processes, e.g. propane
