(Harold Postic / AFP/ Getty Images) By JOSEPH SERNA FEB. 1, 2021 6 AM PT When wildfires roar through a forest and bulldozers dig into the earth to stop advancing flames, they may be churning more into the air than just clouds of dust and smoke, scientists say. Those dark, billowing plumes of smoke that rise on waves of heat during the day and sink into valleys as the night air cools may be transporting countless living microbes that can seep into our lungs or cling to our skin and clothing, according to research published recently in Science.

This Solajet™ represents the first collaboration in the Asia-Pacific region to explore the use of Solajet™ in commercial aviation. The companies intend to use Solazyme's technology platform to help provide the Australian market with renewable aviation biofuel. There is currently a six billion liter a year demand for aviation fuel in Australia. Through this collaboration, both Qantas and Solazyme are striving to help meet this demand.

The blended fuel evaluation combined additional analyses from Boeing, Parker ESD and Pratt & Whitney. The evaluation found no significant differences in engine stability, thrust response or engine steady-state performance. This certification clears the C-17 to fly on a volumetric blend of up to 50 percent HRJ fuel with 50 percent JP-8, as well as a blend of 25 percent HRJ, 25 percent synthetic paraffinic kerosene fuel, and 50 percent JP-8.

  • Gas-To-Liquids (GTL): a Review of an Industry Offering Several Routes for Monetizing Natural Gas David A
    1 Gas-to-Liquids (GTL): a Review of an Industry Offering Several Routes for Monetizing Natural Gas David A. Wood DWA Energy Limited, Lincoln, United Kingdom Chikezie Nwaoha Independent Researcher, Nigeria Brian F. Towler Professor and CEAS Fellow for Hydrocarbon Energy Resources, Department of Chemical and Petroleum Engineering, University of Wyoming, USA Draft of Article published in Journal of Natural Gas Science and Engineering Volume 9, November 2012, Pages 196–208 Abstract Gas-to-liquids (GTL) has emerged as a commercially-viable industry over the past thirty years offering market diversification to remote natural gas resource holders. Several technologies are now available through a series of patented processes to provide liquid products that can be more easily transported than natural gas, and directed into high value transportation fuel and other petroleum product and petrochemical markets. Recent low natural gas prices prevailing in North America are stimulating interest in GTL as a means to better monetise isolated shale gas resources. This article reviews the various GTL technologies, the commercial plants in operation, development and planning, and the range of market opportunities for GTL products. The Fischer-Tropsch (F-T) technologies dominate both large-scale and small-scale projects targeting middle distillate liquid transportation fuel markets. The large technology providers have followed strategies to scale-up plants over the past decade to provide commercial economies of scale, which to date have proved to be more costly than originally forecast. On the other hand, some small-scale technology providers are now targeting GTL at efforts to eliminate associated gas flaring in remote producing oil fields.
