Steam / CO2 Reformer Technology
Raven SR Steam / CO2 Reforming 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’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’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’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™ 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™ 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’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 S-Series
Raven SR will convert organic waste with its patented non-combustion process to produce green hydrogen to be resold in commercial fueling stations in Northern California to power passenger and heavy-duty fuel cell vehicles. Raven SR will break ground in 2022 at the Richmond location.
Raven G-series
Raven’ G-Series unit is a modular, gas-to-gas system built around the SR2 that can produce 4,500 kgs of hydrogen/day from renewable or natural gas. It utilizes stranded gas, low methane or otherwise unmonetized gas to create hydrogen affordably and efficiently. The units can be placed on landfills or stranded natural gas wells and have a conversion efficiency of >97% compared to 75% for traditional SMR.
Fischer-Tropsch method
Fischer-Tropsch fuels are synthetic copies of standard fuels, such as diesel, Jet A, Jet B and milspec JP-8. The Fischer-Tropsch process involves reforming synthetic gas to create fuels out of hydrogens and carbons, as opposed to conventional fuels refined from existing hydrocarbons – Fischer-Tropsh synthetic fuels are put together, as opposed to taken apart. As a result, Fischer-Tropsch synthetic fuels are higher purity, and burn more cleanly.

Highest waste utilization
Raven’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™ has a near 100% waste utilization potential.
