The world’s first commercial plant to produce liquid fuels by direct coal liquefaction is now being started up in Majata, Inner Mongolia, by Shenhua Group (Beijing). Designed to produce 25,000 bbl/d of syncrude from 4,300 metric tons per day (m.t./d) of coal, the plant was operated for a 300-h trial at the beginning of this year, then was shut down for modifications. If the current startup goes well...

Algae offer a ubiquitous, renewable source of oil for fuels and various chemical products ( CE, September 2008, pp. 22–25), but the extraction of oil from the algae cells is an energy-intensive process that involves dewatering and drying the biomass, followed by solvent extraction. Now, a one-step method that breaks the algae cells and liberates the oil without the need for dewatering or solvents has...

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; www.lincenergy.com.au), which was formed to research, develop and commercialize the underground...

Petroleum refiners throughout the world are faced with increasing uncertainty regarding future refining margins, crude prices and project costs. These factors, along with falling demand for refined products, a global recession, and tighter credit markets, are forcing global refiners to reconsider, postpone, or cancel expansion projects. At the same time, mandated reduction of sulfur levels in refined...

Strategies for extracting more distillate from petroleum to meet the growing demand for diesel fuel constituted a major theme of the recent annual meeting of the National Petrochemical and Petroleum Refiners Association (NPRA, Washington D.C.; www.npra.gov) in San Antonio, Tex. Worldwide, the demand for distillate is expected to increase by more than 5 million bbl/d over the next 10 years, says Richard...

Researchers at United Environment & Energy (UE&E; Horseheads, N.Y.) have developed a catalyst for the efficient conversion of algae to biodiesel. The mixed-metal oxide catalyst (comprised of metals that are resistant to corrosion yet reactive) facilitates the transesterification of algae oil and methanol. The mechanism for the reaction over the solid...

A process that produces hydrogen from coal with close to 80% energy conversion efficiency, plus coproduction of a carbon-dioxide-rich stream for sequestration, is being developed at Ohio State University (Columbus, Ohio; www.osu.edu). This compares with around 60% conversion efficiency for traditional coal gasification processes, says Fanxing Li, a research associate and co-inventor of the process along...

In these hard economic times, people working in troubled businesses may well envy the situation of Alberta’s oil sands industry. The Canadian Association of Petroleum Producers (CAPP, Calgary, Alberta; www.capp.ca) predicts that the production of synthetic crude from oil sands will reach 3.3-million bbl/d by 2020, up from 1.2-million bbl/d in 2007. Much of this oil will be sent to the U.S. via an...

A continuous process for producing biodiesel that has a residence time of about one minute, versus several hours for a conventional batch process, has been developed at Oak Ridge National Laboratory (ORNL; Oak Ridge, Tenn.; www.ornl.gov). The process uses a centrifuge for simultaneous synthesis of biodiesel and separation of the biodiesel from the glycerol byproduct. ORNL has done laboratory tests and is...

As an energy resource, global coal reserves represent 2,000 billion barrels of oil equivalent. In 2007, global oil reserves were about 1,300 billion barrels of oil. World wide, oil demand will grow 40 to 50% by 2030. But coal offers an opportunity to diversify worldwide liquid-fuel supplies and coal utilization to produce fuels that can extend the lifetime of world oil reserves. This is a strategic...

Coal is typically cleaned by gravity separation to reduce ash and pyrite content, with flotation used to recover fines. Various methods have been applied to disperse fine clay particles from the surface of coal particles and thus improve coal flotation performance. A team of researchers from the Ian Wark Research Institute, University of South Australia (Adelaide; www.unisa.edu.au), has studied the effect...

A new method for vaporizing liquefied natural gas (LNG) that is more environmentally friendly than the traditional submerged combustion vaporization (SCV) process is being offered by Black & Veatch (B&V; Overland Park, Kan.; www.bv.com). In an SCV process, LNG is passed through stainless steel tubes in a water bath that is warmed by sparging combustion gases from a submerged, gas-fired burner. The...
