Steam / CO2 Reformer Technology

Raven SRSteam / CO₂Reforming System

Steam reforming – no combustion, no pollution, just clean hydrogen and Fischer-Tropsch synthetic fuels

Steam reforming

Steam reforming is the industrial process used to produce synthetic gas, which is the precursor to Fischer-Tropsch synthetic fuels and hydrogen. Raven SR’s patented Steam/CO₂ Reforming process transforms all waste – biomass, municipal solid waste, bio-solids, industrial waste, sewage, medical waste and unwanted, unusable, excess, low methane natural gas – into synthetic gas, which is then converted into renewable energy products including hydrogen, sulfur, and nitrogen-free Fischer-Tropsch synthetic fuels, and additives and solvents.

Raven SR’s reductive chemical reaction does not admit any oxygen into its process, which eliminates combustion and is therefore much a cleaner process that converts all feedstock into fuel – rather than incinerating it. This technology is unique to Raven and requires minimal waste sorting before processing waste methane.

The process

The power and efficiency of Raven SR’s technology lies in its Steam/CO₂ Reforming process, created and patented by the late Dr. Terry Galloway.

The critical difference is that the Raven SR system does not allow oxygen into the process. There is no combustion or catalysts in the process, so rather than burn our feedstock for heat, we convert it to fuel.

In its simplest form, the Raven SR process is straightforward. We heat waste until it turns to synthetic gas, then separate the hydrogen from the carbon. It is then reformed into clean hydrogen or Fisher-Tropsch synthetic fuels, with excess carbon sequestered in a usable powder.

The power of steam gives Raven SR’s technology the ability to convert any carbonaceous feedstock into a synthetic gas that is 55-65% hydrogen – higher than most processes, including plasma arc gasification. This hydrogen-rich syngas produces higher quantities of fuels with fewer emissions than any competing technology.

Raven SR’s Steam/CO2 Reforming process converts 100% of waste. We process multiple and mixed wastes into highest quality synthetic gas. About 15% of feedstock is converted into a solid bio-carbon which can potentially be sold. This means Raven SR has a near 100% waste utilization potential.

Better operations

No tar buildup or hotspot issues, reduces downtime.

Lower cost

Low-atmospheric and no expensive catalysts in the front end.

A cleaner process

Lower emissions are better for GHG reductions as well as possible site locations.

Greater feedstock options

Multiple feedstocks at once, with a moisture content of 30-55% reducing need of screening and drying.

The Raven advantage

Raven SR’s Steam/CO₂ Reforming system produces more syngas from feedstock than conventional steam reforming processes. We produce almost zero waste and do not have downtime or maintenance issues associated with hotspots and tar build-up associated with other combustion-based methods. Our technology is modular and scalable. We do not require waste to be sorted before processing, and we can process methane, eliminating another significant source of pollution and converting it into fuels.

Outputs

Raven SR produces syngas and converts it into SAE J2719 (i.e. 99.999%-pure) hydrogen Fischer-Tropsch synthetic fuels.

Our hydrogen is suitable for use in fuel cells, and our Fischer-Tropsch synthetic fuels are better quality than conventional fuels. They deliver higher engine output and greater torque, have higher energy content per carbon content of the fuel, and our jet fuel is 5% less dense than conventional jet fuel allowing aircraft to fly further on the same load of fuel.

Raven SR’s synthetic fuels have a higher cetane number, reduce NOx by 16.7%, smoke emissions by 40.3%, hydrocarbons by 49%, carbon monoxide by 33% and particulate-matter by 21%.
