Injection Packages
These Packages allow properly to prepare and to inject the Catalyst and Additive, in order to maximize the efficiency of the Axens Technologies.
H-Cat additive Injection Package
The H-Cat Additive is a single molecular catalytic agent introduced in the oil residue feedstock. It is mixed and dispersed well within the oil residue through the H-Cat technology injection package which consists of a pump and mixers to inject and mix with the oil residue. The injection package is placed upstream of the H-Oil Reactor.
The mixing of the H-Cat catalyst and the feedstock ensures easy hydrogen transfer particularly into large asphaltenic molecules that cannot access the active sites of the solid supported catalysts in the ebullated beds increasing the residue conversion rate by at least 10% and produce higher quality distillate yields. It also reduces fouling of tower bottom heat exchangers. The H-Cat technology is suited for upgrading projects using heavier and less- expensive feedstocks.
Advantages:
- Increase the conversion rate of the Residue
- Limit the development of undesired by-products
Catalysts & Additives Injection Packages
Axens scope of supply for the Liquid Catalyst Injection Package includes the engineering, material selection, fabrication, inspection, testing, painting, preparation for shipment and Supplier data for the Liquid Catalyst Injection Package.

Axens can supply these Chemical Injection packages as part of a a global solution, most appropriate to ensure a safe and efficient operation, and a robust design integrated into the overall unit designed by Axens.
Catalyst Sampling Device
The Catalyst Sampling Device is a reliable proprietary sampling system to withdraw a solid catalyst from a gas medium allowing analysis without interfering in the operation of the unit.
During normal operations the catalyst sampling system is used to analyze catalyst carbon content, to identify the nature of any catalyst contamination or poisoning that may have occurred and to detect abnormal carbon deposit.
Key advantages:
- Over 60 References
- Used for the Start-up and Commissioning
- Used for Catalyst Monitoring, helping operators to adjust regeneration section operating parameters, while keeping the unit running
Texicap™
Fixed-bed radial-flow reactors are used when low-pressure drop is critical to performance, such as in reforming units. Most fixed-bed radial reactor designs “waste” the top 15% or so of the catalyst bed, since conventional design create “dead-zones”.
Indeed, when the bed catalyst settles, a gap appears between the top of the bed and cover plate. To prevent reactants from bypassing the catalyst, Axens has developed and patented an extremely cost-effective way to recover unused bed volume, and ensures complete utilization of loaded catalyst and platinum inventory.
