Catalytic Liquefier is an advanced emission reduction technology that minimizes harmful pollutants from petrol, diesel, CNG engines, and industrial exhaust systems. Using innovative catalytic and chemical reactions, it reduces CO, CO₂, NOₓ, SOₓ, and hydrocarbon (HC) emissions by converting harmful gases into heat, water vapor, and specific non-toxic liquid by-products.
The technology optimizes combustion efficiency, improves air quality, and helps industries comply with environmental regulations. Suitable for automobiles, generators, boilers, and manufacturing plants, its modular design enables easy installation with minimal modifications. Catalytic Liquefier provides a cost-effective, sustainable solution that supports cleaner operations, reduced greenhouse gas emissions, and a healthier environment.

Beyond conversion. Liquefaction.
A standard catalytic converter converts CO → CO₂, HC → CO₂ + H₂O and NOx → N₂ — but still releases gases into the atmosphere. The Catalytic Liquefier goes a step further, condensing a portion of the exhaust stream into liquid form for collection and reuse — which is where the name comes from.
In short, it means: convert what can be converted, and liquefy what can be liquefied — leaving as little as possible simply vented to atmosphere.
Two commitments guide every unit we engineer and every plant we work with.
"To lead India's industrial and automotive sectors toward near-zero gaseous emissions, where exhaust from every engine and stack is captured, converted and partially liquefied — protecting public health and enabling sustainable industrial growth."
"To design and deploy affordable, field-proven emission-control technology that helps manufacturers and industries exceed CPCB & MoEF compliance benchmarks, while recovering value from what would otherwise be waste gas."
B.Tech mechanical engineer with a deep passion for environmental engineering.
Witnessing the severe air pollution challenges faced by Indian industrial towns and city traffic, Rohit dedicated years of research to develop a technology that could realistically and affordably solve the emission crisis — not by displacing pollution, but by converting and recovering it.
After years of iterative research, he developed the Catalytic Liquefier — a device that simultaneously addresses multiple categories of pollutants from petrol, diesel and CNG engines and industrial exhaust, while recovering heat and creating recoverable liquid byproducts. The technology received NIDHI PRAYAS support from DST, Government of India, and was independently tested at ARAI and the National Chemical Laboratory.
Mission: to make every Indian tailpipe and industrial chimney a source of clean air — not pollution. Company: Catalytic Liquefier Pvt Ltd · CIN U28299MH2025PTC451516 · Stage: Validation.
A three-stage approach to converting raw exhaust into clean, compliant, and partially recoverable output — replacing traditional catalytic converters and scrubbers.

Exhaust is captured directly from engine tailpipes or industrial stacks via precision intake manifolds, with flow, temperature and composition continuously sensed.

Gases pass through our patented catalyst matrix, where CO, CO₂, NOx, SO₂, HC and CH₄ undergo controlled chemical transformation into neutral compounds.

Exhaust gases are converted into heat, water vapor and specific liquid forms — working toward minimizing or eliminating gaseous emissions from the exhaust stream entirely.
We are not just delivering a device; we are creating a meaningful impact that resonates through public health, regulatory compliance, and industrial competitiveness.
Performance was tested on emission gases at the Automotive Research Association of India (ARAI) and National Chemical Laboratory (NCL). The system demonstrated effective control of CO, CO₂, NOx, HC and CH₄ gases, smoke and particulate matter under different petrol, diesel and industrial operating conditions.

The catalytic liquefier was used to convert gaseous emissions into liquid form, primarily focusing on SO₂. The process was consistent across all engine types and power levels.
| Gas Type | Input Concentration (g/kWh) | Liquefied Output |
|---|---|---|
| CO₂ | 120 – 210 | 86% |
| NO₂ | 0.10 – 0.40 | 91% |
| HC | 1.0 – 2.0 | 55% |
| SO₂ | 0.15 – 0.40 | 91% |
FTIR (Fourier-Transform Infrared) testing identifies chemical compounds, gas compositions and functional groups in the liquefied output. ARAI testing verifies emission-reduction performance and measures fuel-efficiency improvement — Test Report No. ERL/2025-26/3000047453, dated 25-Sep-2025.
