Texas Approves First Additive for Biodiesel to Reduce NOx Emissions

March 13, 2007

The Texas Commission on Environmental Quality (TCEQ) has approved a biodiesel fuel additive, which reduces tailpipe emissions of oxides of nitrogen emissions (NOx) to levels low enough that the fuel can qualify as Texas Low Emission Diesel (TxLED). The additive is manufactured by ORYXE Energy International, which produces the additive for standard diesel at its blending facility in Pasadena, Texas.

In a March 9 press release, the company said it had received official notification from TCEQ that ORYXE LED for Biodiesel has been approved for use in Texas. The additive is the first to be approved by the state. Fuel producers can now blend the additive directly into diesel blends that contain up to 20 percent biodiesel (B20).

Before approving the additive, the TCEQ reviewed the results of emissions tests conducted at West Virginia University Engine and Emissions Research Laboratory, a facility that is equipped with engine dynamometers for performing heavy-duty engine emissions certification tests for the U.S. Environmental Protection Agency. The tests were funded in part by the state of Texas through a grant from TCEQ.

NOx is a major contributor to ozone pollution and is a serious problem in many areas of Texas. The TxLED program was launched in November of 2005 to reduce NOx emissions from diesel exhaust in 110 counties, including the metropolitan areas of Houston, Dallas-Ft. Worth, Austin and San Antonio.

Founded in 2001, ORYXE Energy International, Inc. is based in Irvine, California. It develops, certifies, and distributes proprietary additives that improve fuel performance and reduce toxic emissions from the combustion of gasoline, diesel, residual fuel, and other distillates.
