Biocatalysts for biodiesel production

Researchers from the Department of Environmental and Applied Chemical Engineering, Gangneung-Wonju National University (Gangneung, South Korea; www.gwnu.ac.kr) are developing a two-step enzymatic route to biodiesel fuel that promises to reduce production costs. The process employs a lipase-producing bacterium and, sequentially,…

A new catalyst reduces SO2 emissions from H2SO4 plants

At last month’s Sulfur 2010 Conference (November 1–4; Prague, Czech Republic), Haldor Topsøe A/S (Lyngby, Denmark; www.topsoe.com) introduced its latest sulfuric-acid catalyst, VK-701 Leap5, which promises to help operators of sulfuric acid plants meet more-stringent SO2-emission limits. When used in…

New catalyst approach for methane-to-ethylene conversion

A nanotechnology-based, bottom-up approach to synthesizing catalysts for converting natural gas to ethylene could enable an alternative to the steam-cracking of crude oil, an energy-intensive process conventionally used to produce ethylene, the world’s most valuable commodity chemical. Scientists at the…

Nanoclusters that selectively catalyze oxidation reactions

Professor Shu Kobayashi, University of Tokyo (Tokyo, Japan; www.s.u-tokyo.ac.jp), has discovered that bimetallic nanoclusters can catalyze the oxidation of alcohols. Kobayashi’s group has demonstrated the ability to control the reaction pathways of alcohol oxidation to aldehydes, carboxylic acids or esters…
