MAXCEL Claus Catalyst
Porocel’s comprehensive array of sulphur recovery catalysts are backed with comprehensive technical support and customer service that is second to none. Maxcel quality catalysts and expert services help keep your sulphur recovery operations running smoothly and efficiently – so the rest of your refinery can, too.
MAXCEL 727 - spherical activated alumina catalyst designed specifically for the Claus reaction.
High surface area.
Mass transfer benefits provided by high macroporosity of 0.2cc/g.
MAXCEL 777- extruded Titania Claus Catalyst
High Quality Titania Claus Catalyst
High Conversion of COS and CS2 to H2S
Excellent Chemical & Physical properties providing long service life and the ability to withstand process upsets
Superior resistance to sulphation poisoning
Allows higher space velocities for the same sulphur conversion, which may result in smaller Claus SRU reactor volumes for new or retrofit units.
Maxcel SD-A - The best choice for sub-dew point Claus processes
MAXCEL 740 - spherical Oxygen protection catalyst
In sulphur recovery units with fired reheaters, oxygen ingress can cause significant Claus catalyst deactivation. This deactivation occurs due to sulphation, the formation of a stable aluminum sulphate layer on the Claus catalyst active sites. However, this deactivation can be mitigated by including a small guard layer of Maxcel 740 in the top of the catalyst bed.
Maxcel 740 is a true oxygen catalyst, not an oxygen scavenger
Maxcel 740 will not become “saturated” with oxygen. Instead, Maxcel 740 facilitates the reaction of trace oxygen with sulphur compounds present in the gas. By converting this oxygen before it comes into contact with the pure alumina catalyst below, the effects of catalyst deactivation by sulphation can be reduced. Maxcel 740 is typically installed in the second and third Claus converter when fired reheaters are present upstream.
Maxcel TGS Tail Gas Catalysts
Maxcel TGS-01: Conventional temperature applications
Maxcel TGS-01 is a spherical cobalt-molybdenum (CoMo) on activated alumina catalyst for use in conventional
tail gas treating units that contain a hydrogenation reactor (typical reactor inlet temperature of _260°C / 500°F). Maxcel TGS-01 provides the best balance of catalyst activity and pressure drop for conventional tail gas treating
units, offering about 30% less pressure drop than competitive catalysts while delivering comparable activity.
Maxcel TGS-02 Low temperature applications
Maxcel TGS-02 is a spherical cobalt-molybdenum (CoMo) on activated alumina catalyst used in low temperature tail gas treating units. Maxcel TGS-02 outperforms competitive low temperature tail gas catalysts without increasing pressure drop across the reactor.
Top Bed Grading
CatGuard® PMT products
A Top Bed Grading Package to Protect your Main Hydrotreating Catalyst Bed
Hydrotreating units are generally configured with a top bed grading package to protect the main catalytic bed from fouling as well as poisoning in order to improve its cycle length. A well designed
system of top bed grading will prevent such problems in order to maximize the unit performance. Porocel offers a complete line of top bed grading products together with technical support to ensure proper selection.
