摘要

Dimethly ether (DME) is a clean fuel that does not produce toxic gases or particulate matter (PM) at burning. JFE Group develops a direct synthesis process of DME which has advantages in economics. Construction of a demonstration plant with 100 t/d capacity was finished in Nov. 2003. The first demonstrating operation (Run 100) through Dec. 2003 to Jan. 2004 and the second operation (Run 200) through June 2004 to Aug. 2004 were completed successfully. The conversion of synthesis gas, the selectivity to DME and the purity of DME reached to 96 percent (Target: more than 95 percent), 93 percent (Target: more than 90 percent) and 99.6 percent (Target: more than 99 percent), respectively. As an application technology of DME, a DME diesel generation system is now under development. Its demonstration test facility has 1 250 kW capacity and a Nox reduction system using DME as a reducing agent.
