SAO PAULO, Nov. 9 /PRNewswire/ -- Braskem S.A. ("Braskem"), in compliance with CVM Instruction 358/02, announces to shareholders and the market that, in association with IDESA, a traditional Mexican corporate group, it won the auction held by Pemex Gas, a state-owned Mexican company, for the acquisition of ethane, which will be used as feedstock for an integrated petrochemical project to be developed in that country ("Project Ethylene XXI"). Project Ethylene XXI, which is scheduled to...

Scientists in Washington, D.C. are reporting laboratory evidence supporting the possibility that some of Earth's oil and natural gas may have formed in a way much different than the traditional process described in science textbooks. Their study is scheduled for Nov./Dec. issue of ACS' Energy & Fuels, a bi-monthly publication. Anurag Sharma and colleagues note that the traditional process involves biology: Prehistoric plants died and changed into oil and gas while sandwiched between...

Researchers at the University of Washington and the University of North Carolina at Chapel Hill have taken an important step in converting methane gas to a liquid, potentially making it more useful as a fuel and as a source for making other chemicals. Methane, the primary component of natural gas, is plentiful and is an attractive fuel and raw material for chemicals because it is more efficient than oil, produces less pollution and could serve as a practical substitute for petroleum-based...

A team of international scientists led by Mirjam Langhans, from the German Aerospace Center (DLR), will present first results of a global analysis of spatial patterns, occurrence and origin of river channels on Titan at the European Planetary Science Congress in Potsdam, Germany, on Wednesday September 16. To date scientists have focused their investigations on single channels due to the fact that radar and spectral data have only been captured for some narrow areas of the surface below the...

A team of University of Hawai'i at Mānoa researchers led by Ralf Kaiser, physical chemist at UH Mānoa, unraveled the chemical evolution of the orange-brownish colored atmosphere of Saturn's moon Titan, the only solar system body besides Venus and Earth with a solid surface and thick atmosphere. The UH Mānoa team, including Xibin Gu and Seol Kim, conducted simulation experiments mimicking the chemical reactions in...

"It is really surprising how closely Titan's surface resembles Earth's," says Rosaly Lopes, a planetary geologist at the Jet Propulsion Laboratory (JPL) in Pasadena, California, who is presenting the results on Friday, 7 August. "In fact, Titan looks more like the Earth than any other body in the Solar System, despite the huge differences in temperature and other environmental conditions." The joint NASA/ESA/ASI Cassini-Huygens mission has revealed details of Titan's geologically young...

The oil and gas that fuels our homes and cars started out as living organisms that died, were compressed, and heated under heavy layers of sediments in the Earth's crust. Scientists have debated for years whether some of these hydrocarbons could also have been created deeper in the Earth and formed without organic matter. Now for the first time, scientists have found that ethane and heavier hydrocarbons can be synthesized under the pressure-temperature conditions of the upper mantle...

HAMPTON, Va., April 2 /PRNewswire-USNewswire/ -- NASA scientist Michael Mumma and his team of researchers have discovered methane on Mars, indicating the planet is still alive -- either in a biologic or geologic sense. "The big question is, 'What is the origin of this methane now being released,'" Mumma says. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) While living systems produce more than 90 percent of Earth's atmospheric methane, other purely geological processes,...

WASHINGTON, Jan. 15 /PRNewswire-USNewswire/ -- A team of NASA and university scientists has achieved the first definitive detection of methane in the atmosphere of Mars. This discovery indicates the planet is either biologically or geologically active. (Logo: http://www.newscom.com/cgi-bin/prnh/20081007/38461LOGO) The team found methane in the Martian atmosphere by carefully observing the planet throughout several Mars years with NASA's Infrared Telescope Facility and the W.M. Keck...

New research is challenging the recent finding that plants could be a major source of the atmosphere's methane levels. A study from 2006 suggested plants could account for almost half of the global production of the greenhouse gas, yet a UK-based team has found that under normal conditions, plants just convey methane from the soil to the air without actually producing it. The research suggests identifying sources of methane is key for climate control, as the gas is about 20 times more potent...

Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...
