Biogas

Biogas and Renewable Natural Gas (RNG) are transforming organic waste into usable energy — fueling power generation, vehicle fleets, and pipeline networks. Produced through anaerobic digestion at landfills, farms, and wastewater plants, biogas represents a clean, renewable complement to solar and wind power. But to reach its full potential, biogas must be purified.

Turning Waste Gas into Renewable Power

Hydrogen sulfide, siloxanes, VOCs, and nitrogen can corrode equipment, lower efficiency, and violate pipeline standards. R3 Carbons’ engineered activated carbons remove these impurities — ensuring compliance, safety, and profitability in every cubic foot of gas.

biogas sulfur — Catalytic and impregnated grades neutralize hydrogen sulfide at the source — protecting compressors, pipelines, and membranes from corrosive damage.

biogass emissions — VOC and odor adsorption reduces harmful emissions and ensures regulatory compliance — turning flares into clean, efficient combustion.

biogas engine — Advanced siloxane media prevent silica buildup in turbines and engines, minimizing downtime and extending service intervals.

biogas nitrogen — PSA-grade carbons selectively separate nitrogen to produce high-BTU renewable natural gas ready for injection into utility pipelines.

biogas circular — R3 Carbons closes the loop with reactivation and recycling programs — lowering lifecycle costs while reducing carbon footprint.

Hydrogen Sulfide

Hydrogen sulfide (H₂S) is one of the most destructive components in biogas, corroding metals, degrading lubricants, and creating foul odors. Even small concentrations can damage compressors, membranes, and engines — or make gas unsuitable for pipeline injection.

R3 Carbons activated carbon capture and convert H₂S into elemental sulfur, protecting downstream systems and extending service intervals. Designed for chemisorptive performance, these media enable reliable compliance with air permits and maximize gas value across RNG and energy applications.

Volatile Organic Compounds

Volatile organic compounds (VOCs) in landfill and digester gas degrade membranes, corrode seals, and raise SO₂ and NOx emissions. These compounds must be removed to protect upgrading systems and maintain downstream reliability.

R3 Carbons’ carbon media adsorbs VOCs, terpenes, and odorants while preserving methane purity. Regenerable through temperature swing adsorption or used as a disposable polishing layer, R3 delivers sustainable performance and reduced environmental impact.

Eliminate VOCs and Odors >

Siloxane

Siloxanes from consumer and industrial waste can devastate combustion systems — forming silica deposits that clog engines and reduce power output. Even trace levels cause costly downtime and accelerated wear.

R3 Carbons’ carbon media uses advanced surface chemistry to preferentially adsorb siloxanes over hydrocarbons, ensuring long-term system integrity. Optimized pore design and high silica-loading capacity keep turbines and engines performing at peak efficiency.

Protect Turbines and Engines >

Nitrogen

Nitrogen (N₂) infiltration lowers BTU value and disqualifies RNG from pipeline injection. Removing N₂ is key to meeting strict gas specifications and improving economics.

R3 Carbons provides precise selectivity in PSA nitrogen rejection systems, separating N₂ and CH₄ for high-purity RNG. Engineered for durability and low pressure drop, it delivers consistent performance across demanding cycles.
