Carbon Dioxide as Chemical Feedstock Michele Aresta

Carbon Dioxide--A Renewable Feedstock for Chemical and Fuel Industries. This requires less energy per ton of CO2 than most other electrochemical conversion pathways. The algae would be exposed to sunlight, in water mixed with carbon dioxide, and would give off ethanol and oxygen. Dow wants the ethanol as a feedstock for plastic, replacing natural gas. Share this: This edition of Future Tech Alert profiles utilization of carbon dioxide as a renewable feedstock. The company and Dow Chemical are expected to announce on Monday that they are building a pilot plant on the site of a Dow plant in Freeport, Tex., that produces carbon dioxide as a by-product of several different processes. 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. Using carbon dioxide as a feedstock can make an excellent contribution to the environment. 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. Carbon dioxide gas may be liquefied or solidified. 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.
