Product Demonstration Unit

We designed, built and have operated a fully-integrated biomass and natural gas-to-synthetic fuels demonstration facility in Commerce City, Colorado. Over the course of operating this Product Demonstration Unit, or PDU, we have obtained sufficient data on our alternative energy technologies that can be used for commercial application.

The primary technologies integrated at the PDU are the Rentech-ClearFuels biomass gasifier, a natural gas steam methane reformer, the Rentech Fischer-Tropsch Process, and hydro-cracking and hydro-treating technologies.

At the PDU, the Rentech-ClearFuels gasifier has run for over 2,200 hours, the Rentech Fischer-Tropsch Process has operated for over 13,000 hours, and the integrated, end-to-end, biomass-to-fuels process has operated for more than 1,000 hours.

The PDU is located on approximately 17 acres in an industrial area in Colorado adjacent to a rail line and an interstate highway. Approximately six acres of the site are occupied by the PDU, and the remaining approximately 11 acres of the site are available for other uses. There is an approximately 12,000 square foot building on that site that is primarily used for laboratory and maintenance functions supporting the PDU. We also lease a 2 1/2 acre industrial site located adjacent to the site, which includes a single building of approximately 3,000 square feet and is used for the storage and maintenance of construction equipment. Rentech is currently seeking parties interested in purchasing the PDU and/or the site.
