APPLICATIONS

Hydrocracking catalysts typically composed of metal sulfides (nickel, tungsten, cobalt, and molybdenum) are used for processing feeds containing polycyclic aromatics that are not suitable for typical catalytic cracking processes.

The water gas shift reaction is an important element in the hydrogen lifecycle and the push toward net zero technologies. The combination of catalysts, often copper-zinc-alumina and iron-chromium, are characterized by TPR and pulse chemisorption maximize activity.

Fischer–Tropsch synthesis converts syngas into sustainable fuels, with cobalt and iron catalysts playing a key role. Chemisorption and TPR techniques help optimize metal dispersion and reducibility, directly enhancing catalytic performance.

Reforming: Catalysts containing platinum, rhenium, tin, etc. on silica, alumina, or silica alumina are used for the production of hydrogen, aromatics, and olefins.

Isomerisation: Catalysts such as small-pore zeolites (mordenite and ZSM-5) containing noble metals (typically platinum) are used to convert linear paraffins to branched paraffins.

Partial Oxidation: Manganese, cobalt, bismuth, iron, copper, and silver catalysts used for the gas-phase oxidation of ammonia, methane, ethylene, and propylene are characterized using: Temperature-programmed oxidation and desorption, heat of desorption & dissociation of oxygen.

Hydrogenation: Catalysts like palladium, nickel, and platinum rely on chemisorption to activate hydrogen and substrate molecules, with techniques like pulse chemisorption and TPR used to fine-tune activity and selectivity.

Catalytic Cracking: Acid catalysts such as zeolites are used to convert large hydrocarbons to gasoline and diesel fuel. The characterization of these materials includes: Ammonia chemisorption and temperature-programmed desorption.

ACCESSORIES

OPTIONAL ACCESSORIES

Zeolite Trap
Replaces the cold trap, avoiding the need to create slush baths. Hydrophillic zeolite in a U-tube is placed in-line between the sample and the TCD, adsorbing all water vapour produced during catalyst reduction.

Mass Spectrometer
Provides a direct probe for the identity and quantity of specific reaction products. Includes heated transfer line, trigger cable for remote data acquisition, and data recording/ integration with MicroActive software.

Cryocooler
Enables the start of an analysis at sub-ambient temperature, down to -100ᵒC

MicroPrep
Used to outgas the zeolite trap in-situ, fully regenerating it after saturation from sample prep and TPR experiments.

BET Option
Allows for in-situ BET surface area measurements.
