A new method for using gaseous compounds to produce energy, while also removing harmful by-products, was invented by ORNL researchers. This invention offers an efficient use of waste products, such as sulfurous compounds or carbon monoxide, and can reduce the overall cost of industrial operations. Industrial processes often output gas by-products that are either processed as waste or directly rel…

Microorganisms to Speed Production of Biofuels Researchers at ORNL developed microorganisms that can quickly overcome the resistance of biomass to breakdown, and improved both the cost and efficiency of the biofuel conversion process. Conventional biomass pretreatment methods release sugars, weak acids, and metabolic by-products that slow down or even stop fermentation, resulting in slower biofu…

A more efficient reaction and separation process for reaction products was invented by ORNL researchers. This method is specifically applicable to the production of biodiesel through the esterification of organic oils and fats. In conventional biodiesel manufacturing, esters and glycerines are separated by allowing the products to sit undisturbed for 24 hours. This process is problematic for two…

Manufacturing Biodiesel from Triglycerides ORNL researchers have developed an apparatus that manufactures biodiesel by the reaction of triglycerides with an alcohol and subsequently separates the biodiesel product from the glycerol byproduct. The invention represents an advancement in centrifugal contactor technology in that the new device makes it possible to adjust and control the time in the r…

Treatment of Fuel Process Wastewater Using Fuel Cells ORNL researchers invented a method using microbial fuel cells for cleansing fuel processing water of hydrocarbon by-products and metal salts. This cost efficient method can be used on-site, so that water does not need to be transported to a treatment facility. It also permits fuel processing water to be safely discharged into the environment o…

High-Performance Plastics from Renewable Sources Lignin, a complex polyphenol found in lignocellulosic biomass, is the third most abundant natural polymer and accounts for up to 30% by weight of wood. This valuable by-product of the biorefinery and pulp and paper industries is produced in quantities exceeding 200 million metric tons annually. Significant commercial potential exists for the conv…

Microbial Fuel Cells Offer Innovative Technology for Oil, Gas Industry and Biorefineries Researchers at ORNL have developed several concepts of importance to the oil, gas, and biorefinery industries, using microbial fuel cells (MFCs) to treat wastewater generated in oil and gas production, to neutralize harmful petroleum by-products, and finally, to increase ethanol yields at biorefineries in eac…
