OUR FUEL PROCESS

Instead of going to the landfill, household garbage is redirected to our Feedstock Processing Facility, where metals and other inorganic materials are separated from organic waste and recycled or disposed of at the landfill. Our processing system then sizes, sorts, processes and dries the organic waste, producing a light "confetti-like" feedstock that is ready for gasification at the Biorefinery.

The prepared feedstock is then processed through our gasification system which incorporates several key systems and pieces of equipment. Here, the waste is heated in a low-oxygen environment and reacts with steam in a bubbling bed gasifier to form carbon monoxide and hydrogen molecules. We’ve added additional equipment in our gasification system that helps convert unreacted material, maximizing our syngas production.

The syngas clean-up stage removes particulate, acid gas and excess water from the syngas in a wet scrubbing process. Additional syngas clean-up steps remove unwanted impurities and adjust the carbon monoxide and hydrogen ratio in the syngas so that it is ready for processing in our Fischer-Tropsch system.

The Fischer-Tropsch, or FT, process utilizes a catalyst filled tubular reactor to convert the carbon monoxide and hydrogen in the syngas into a mixture of paraffinic hydrocarbons, or syncrude. The syncrude, which is then separated from the unreacted syngas, flows through to the upgrading process. The unreacted syngas is recycled back through the FT Reactor for conversion to syncrude, increasing the efficiency and yield of our process.

The upgrading process cracks the syncrude down into smaller chain hydrocarbons where the jet fuel or diesel fraction is separated from the mixture and longer chained hydrocarbons are recycled back to the hydrocracker for further processing.
