On-going Drive to Develop Cheaper Clean Alternative Fuels Contents

A domestic research team succeeded in developing the technology of producing next-generation and highly efficient clean fuel DME (liquefied petroleum gas containing oxygen). DME is a cheaper and less pollution-generating alternative fuel.

The Korea Chemical Research Institute (KCRI) announced on January 13, 2005 that it had developed the DME production technology involving highly active catalysts in collaboration with the SK Institute of Technology (SKIT).

DME is currently applied to a number of spray-type cosmetic products. If it is used as car fuel, it could emit carbon dioxide 8% less than diesel and 18% less than LPG. Likewise, this can be called as a next-generation clean energy causing almost no pollution.

To develop the highly active catalyst, the KCRI mixed the insoluble and porous nano-material “Zeolite” with other materials, changed its features and adjusted the activation point. The newly developed highly active catalyst doesn’t produce hydrocarbon by-products.

So far methane has been used as catalyst to produce DME. But methane produces lots of moisture in the process and requires additional procedure to remove the moisture. Therefore, it consumes more energy.

With the new DME catalyst developed by SKIT, the additional drying process is unnecessary. In addition, the reaction chamber size can be reduced in half, and high-efficiency can be achieved even at low temperatures, thereby saving 30% of the energy cost compared with the methane method.

Dr. Gi-won Jeon of the KCRI, 47, forecast that within 3 years from now, Korea is expected to apply this technology to produce small amount of DME, and within 5~6 years it is expected to secure the technology to produce a large volume of DME equal to 10,000 tons per day.

Producing 10,000 tons of DME means that the CO2 emission can be lessened by 135,000 tons and 70 billion won of energy cost can be saved.

The KCRI had completed the patent filing process of this technology in last October in Korea, the US and Japan, and signed a technology transfer agreement with SK Corp at the end of last December.

SK Corp will make full-fledged efforts to commercialize this technology and sets a goal of rolling out DME in large quantity in 5 to 6 years.
