Composite liquid and slurry boiler fuels have been produced from mixtures of various waste materials, such as biomass, coal- and crude-oil-processing residues, wood and other combustible substances, in a collaboration between researchers at the University of Rhode Island (Kingston, R.I.) and Podgorny Institute (Kharkov, Ukraine). The researchers have formed a company, InEnergy LLC (Naples, Fla....

Synfuels China Technology Co. (Beijing; says it has developed a high-temperature slurry Fischer-Tropsch (F-T) process (flowsheet) that produces mainly clean diesel, naphtha and liquefied petroleum gas (LPG) products, with unique features including: high productivity of proprietary catalyst; efficient recovery of reaction heat by producing 2.5–3.0-MPa(g) steam, which can be...

The Yankuang Group (Zoucheng City, Shandong Province;, one of China’s largest coal companies, and Accelergy Corp. (Houston;, are jointly developing a large-scale, low-carbon, coal-to-liquids (CTL) plant incorporating both direct and indirect liquefaction, in Erdos in China’s Inner Mongolia Province. The plant, which will produce 68,000 bbl/d of fuel per day, will...

An underground coal-to-liquids (UCTL) technology is undergoing pilot testing at Oak Park, near Melbourne Australia, where a metric ton of brown coal is expected to yield about one barrel of oil suitable for use as refinery feedstock on an oil-parity price basis. UCTL takes place within the underground coal seam, whereby low rank coals are liquefied into crude oil substitute product at 300°C. Heat...

Practically all of the coal-fired power plants in the U.S. collect ash from the bottoms of their boilers using a wet system — the ash falls into hoppers that are partially filled with water, and once or twice per shift the slurry is pumped to a settling pond or solid-liquid separation tanks (dewatering bins). In a break from that norm, Seminole Electric Cooperative, Inc. is switching its two 650-MW...

Metso (Helsinki, Finland; is supplying a 140-MWth biogasification plant to Vaskiluodon Voima Oy in Vaasa, Finland. When it starts up in December 2012, the €40-million gasification plant, which will be located next to the existing 565-MW coal-fired power plant, will convert biomass (mainly forest residues) into a so-called biogas that can be combusted with coal. The gasification facility...

An Australian team including CSIRO (Melbourne; and the Uni- versity of Newcastle ( has developed an alternative pathway for producing ultra-low-ash coal that, the team believes, can be used to fuel diesel engines, thus providing the opportunity for diesel engines to replace steam engines for large-scale base-load power generation. The method involves slurrying and...

Ube Industries, Ltd. (UBE; www. and HighChem Co. (both Tokyo; will license their technologies for transforming coal-derived synthesis gas (syngas) into manufacturing ethylene glycol (MEG) — a polyester feedstock — to Qianxixian Qianxi Coal Chemical Investment Co. (Guizhou, Qianxixian, China). The license covers a process...

The world’s first demonstration plant combining underground coal gasification and gas-to-liquids (GTL) technologies in the same facility was officially opened on April 22 in Chinchilla, 350 km northwest of Brisbane, Queensland, Australia. The plant is operated by Linc Energy Ltd (Brisbane;, which was formed to research, develop and commercialize the underground...
