The plant, or Product Development Unit ("PDU"), is currently being constructed by Rentech, Inc., a leading developer of technologies and projects that transform under-utilized energy resources into clean alternative transportation fuels. The PDU will provide finished product to end users for testing purposes as well as being a training facility for Rentech's patented and proprietary process. The plant will produce approximately 10 barrels per day of ultra-clean transportation fuels from coal.

Jonathan Wilkinson, President and CEO of QuestAir said that QuestAir's H-3200 pressure swing adsorption ("PSA") system will purify hydrogen for use in the upgrading of liquid fuels in the coal-to-liquids plant.

"We are extremely pleased to be working with Rentech on this project, which we believe is the first fully integrated coal-to-liquids facility in the US," said Wilkinson. "This technology has the potential to convert large under-utilized resources including coal, into clean burning transportation fuels to supplement dwindling and ever more expensive supplies of conventional oil. We are excited by the potential growth opportunity that the emerging synthetic fuels market offers for our proprietary hydrogen purification technology."

About QuestAir H-3200

QuestAir's H-3200 purifies hydrogen-containing gas streams to high purity hydrogen for use in industrial processes, on-site hydrogen plants and hydrogen fueling stations. The H-3200's optimized Pressure Swing Adsorption ("PSA") process and proprietary rotary valve technology deliver higher efficiency than conventional PSA systems in a more compact, cost effective package. Since the product launch in 2003, QuestAir has sold more than 30 H-3200 systems to customers in Europe, Japan and North America.
