Ambient temperature
is enough
Physical binding needs no reaction window, no 250 °C to maintain, no injection-temperature corridor to chase through load swings.

Krajete's technology is adsorption on tailored zeolite media: frameworks tuned to trap target molecules, NOx above all, from industrial gas at ambient temperature, then release them as a concentrated, recoverable stream under gentle heating while the media return to service. No reagent dosing, no catalyst inventory, no process-water circuit. This page covers the physics, the media, the hardware (50–18,000 m³/h), the measurement discipline, and how the technology licenses for scale-up.
How does adsorption
capture NOx?
A zeolite is a crystalline framework laced with pores a few molecules wide, a vast internal surface folded into a small volume. Molecules that fit the pore geometry and chemistry are held there by physical binding: strong enough to strip NOx out of a moving gas stream, gentle enough to reverse. That is the whole trick, and it has three consequences engineers care about:
Ambient temperature
Selectivity is designed,
not dosed
Pore size and framework chemistry decide what is captured; the media is the selectivity. Nothing is injected into your gas.
The bond reverses
on demand
Moderate heating releases the captured NOx as a concentrated stream and restores capacity, the media survive the cycle, which is why there is no reagent bill and no catalyst change-out.

release
Concentrated enough to handle simply: neutralise it, or recover it.
Gentle heat
Why “tailored” is the operative word
Every cycle teaches more
Loaded media go back to the laboratory for composition analysis under chain-of-custody, every cycle teaches the model more about your stream.
The science
got harder.
The promise
got simpler.
Fifteen years of adsorption research, down to one sentence:
send us one sample, we'll tell you what's really there.
What happens
at regeneration?
When a bed approaches saturation, it is taken offline — flow shifts to a parallel bed, and heated gently. The captured NOx leaves as a small, concentrated stream; the bed cools and returns to service. Two things about this step matter commercially:
The energy asymmetry
SCR must heat your entire flue flow to reaction temperature, continuously. Regenerative adsorption heats only a saturated bed, briefly, on a schedule, in current field practice a fortnightly-class cadence tuned to load. You pay to warm a vessel, not a river of gas.
The desorbate is a decision, not a burden
The concentrated stream can be neutralised conventionally, or routed toward recovery as nitric-acid / fertiliser feedstock where site economics justify it. Destruction is optional; recovery is possible. Which path pays is a finding of the feasibility study, not a promise of this page.
What hardware exists today?
| Class | Throughput | Character | Typical use |
|---|---|---|---|
| Bench drum | 50–500 m³/h | ~500 W power draw, bottom-up suction, van-transportable | Slipstream trials, conditioning studies, first field proof |
| Parallel-bed system | to ~10,000 m³/h | Containerised, alternating beds, capture continues through regeneration | Extended pilots, small full stacks |
| Triple-chamber unit | to 18,000 m³/h | Largest current class; slipstream or full-stream on smaller stacks | Pilot-scale delivery ceiling, the honest top of our build scope |
How do we know
the numbers are true?
Because the measurement discipline is built for scrutiny, not marketing: field analyzers at inlet and outlet (O₂ / CO₂ / NO / NO₂ / SO₂ class), high-frequency time series rather than spot readings, daily zero/span calibration with archived certificates, documented detection limits, and chain-of-custody on every sample and media lot. Loaded media return to the Pasching laboratory for composition analysis.
Every pilot runs on a structured data room, methods, calibrations, raw series, daily logs, KPI dashboards, because our reports end their lives in permit files and capital committees, and they are written knowing it.
Where authorities require accredited regulatory measurement, we work alongside your certified measurement body, their numbers, our interpretation.
How does this scale
beyond pilot?
Through your engineering partner, as a package: the design basis (validated ranges, KPI bands, integration engineering from your pilot), the media supply agreement, the licence to the process family, protected by patents, and Krajete's supervision through commissioning and beyond. Your EPC builds what has already proven itself on your gas; we remain responsible for the science for the life of the system.
For engineering firms and corporate development
Licensing conversations start the same way client projects do — with a measured stream and a feasibility case.
