"We not only found a way to remove and store carbon dioxide from the atmosphere while producing valuable H2, we also suggest that we can help save marine ecosystems with this new technique," says Greg Rau, a visiting scientist at Lawrence Livermore and senior scientist at UC Santa Cruz. And chemistry is playing its role in exploring how CO2 may be used as a chemical feedstock to make a range of useful materials and products. Monitoring the development of green within the chemical industry Carbon Sciences, a California-based public company, is developing drop-in gasoline using carbon dioxide and methane gas as feedstock. We carefully control the chemical reaction so that the coal never burns – it is consumed chemically, and the carbon dioxide is entirely contained inside the reactor.” Related Articles: As Coal Use Continues to Grow, China's 'Blackest The Ohio State group typically studies coal in the two forms that are already commonly available to the power industry: crushed coal “feedstock,” and coal-derived syngas. Using coal CO2 as a chemical feedstock would provide locally-sourced energy with lower emissions than oil. The company envisages using the methanol as a feedstock for olefins and aromatics. Achieve dramatic lower emissions levels, as the syngas produced is at higher temperature and pressure, which allows for easier removal of sulfur (SOX), nitrous oxides (NOX) and lends itself to efficient carbon dioxide (CO2) removal as well. As such, turning the gas into a chemical feedstock, rather than allowing it to escape into the atmosphere, is an extremely appealing idea. Japan's Mitsui Chemicals will build a demonstration plant for a new technology to synthesize methanol from carbon dioxide and hydrogen. Gasification is a process through which coal can be transformed into power, chemicals, hydrogen and transportation fuels, capturing the resulting carbon by-product from the coal for sequestration or for enhanced oil recovery. Though the work is ongoing, Olah and Prakash hope to find a low-cost/low-energy method of turning the captured carbon dioxide into methanol - which can be burned as a fuel source and used as a chemical feed-stock. The team demonstrated or carbonate," says Rau.
