CatZyme® is a reactor decontamination chemistry injected into the hot hydrogen sweep to strip residual gases, drive down LELs, loosen solids, and set up safer, smoother catalyst offloads — typically in 4–6 hours before the nitrogen purge. It’s designed to protect precious-metal catalysts and fit the sweep you already run.
Both CatZyme LT and CatZyme RT are free of surfactants, nitrogen, sulfur, phosphorus, cations, and metals, so they can be injected directly into hot H₂ without compromising platinum or other precious catalysts. If you’re wondering “Will this attack my catalyst?”, the short answer is no — this formulation avoids the usual risk additives.
Inject into the hot hydrogen stream, monitor contaminants to below limits (typically 4–6 hours), then displace with nitrogen. Plants report shorter hot-H₂ sweeps and reduced N₂ usage compared to sweep-only programs.
CatZyme accelerates removal of residual gases, LELs, and H₂S, and helps dissolve compacted/solid deposits that restrict flow, improving offload conditions and reducing personnel exposure.
CatZyme LT: Built for lower-temperature injection (≥ ~400 °F) and sensitive precious-metal beds, providing added margin against exotherms while rapidly reducing LELs and freeing deposits. Also available as LTC concentrate to cut drum count and laydown.
CatZyme RT: Broad operating window (~220–340 °C / 425–650 °F) for plants able to run hotter sweeps; strips gases, collapses LELs, and frees compacted fines to tighten purge timelines and improve offload flow.
Yes. By rapidly lowering LELs and removing residual gases, CatZyme helps reduce time under hazardous atmospheres and cuts exposure during catalyst handling — supporting safer turnarounds.
CatZyme is designed to be catalyst-friendly. CatZyme LT in particular provides added margin against exotherms on delicate beds by enabling effective decon at lower injection temperatures.
