Enerkem <br /> Catalytic Synthesis <br /> The final step in Enerkem's proprietary process is the catalytic conversion of the <br /> chemical-grade syngas into renewable biofuels and commercial chemicals. At this stage, <br /> the syngas is composed mainly of carbon monoxide and hydrogen molecules, the <br /> chemicals used to produce liquid methanol and fuel-grade cellulosic ethanol. <br /> Enerkem's novel technology uses well-known reactions and available catalysts to <br /> produce biofuels from syngas in a process that reduces technological costs and risks. <br /> Enerkem also uses a combination of in-process controls and quality analysis to confirm <br /> that all of its products, including ethanol, consistently meet industry specifications. <br /> Enerkem's biofuels facility is designed to operate continuously, 24 hours a day, 7 days a <br /> week, at a throughput of 382 short tons of RDF per day (on a dry basis), or 18 wet short <br /> tons per hour for each gasifier installed. Enerkem has the ability to scale its process by <br /> installing gasifiers in parallel— 2 gasifiers would be installed in Elk River. <br /> Accepted Feedstocks <br /> Enerkem will process the RDF that is currently being produced by the Great River Energy <br /> Resource Processing plant. <br /> It is expected that Enerkem's Elk River facility would accept the same wide variety of <br /> feedstock that has been tested and processed in Enerkem's Canadian facilities, and in <br /> concordance with acceptable feedstocks for cellulosic ethanol as per the United States <br /> Renewable Fuel Standard (RFS 2). <br /> Receipt of RDF <br /> Enerkem would process the RDF produced and received from the Energy Resource <br /> Processing plant transferred via conveyor to the biofuels plant. Enerkem has the <br /> capacity to accept and process all of the current RDF volumes managed at the facility. <br /> The RDF product will be stored in an enclosed bunker system adjacent to the biofuels <br /> plant <br /> Products Produced <br /> Enerkem produces clean cellulosic ethanol, a renewable, non-toxic, water-soluble and <br /> highly biodegradable biofuel.
