Carbon Dioxide as Chemical Feedstock Michele Aresta

There are presently no chemical looping New techniques have been developed for direct processing of coal or other solid carbonaceous feedstock in chemical looping reactors. Because carbon dioxide (CO2) gas is a freely available resource, there are concerted efforts worldwide to convert this molecule into a chemical feedstock. Anastas(Series Editor), Robert H. Waste CO2-derived plastic hits tonne scale. Fossil fuel chemical looping applications had been used commercially with the steam-iron process for coal from the 1900s to the1940s and had been demonstrated at a pilot scale with the carbon dioxide acceptor process in the 1960s and 1970s . What if the chemical industry could use the carbon dioxide produced by power plants to create these and many other products? Waste carbon dioxide has been incorporated into a polymer at bulk scale. Can plants and wood be broken down into useful chemicals for the production of the consumer and One part of the center's research will focus on carbon dioxide as a feedstock, instead of a non-renewable resource such as petroleum. 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 feedstock. This sticky black by-product of the coal gas and coke industries was a major feedstock for the chemical industry from the 1850s, but its use declined after 1920 with the rise of the petrochemical industry. 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. From 1960 the switch from coal gas (a mixture of hydrogen, carbon monoxide and methane, manufactured from coal) to natural gas (naturally occurring methane) for use in homes and industry all but killed off the remaining coal tar industry.

Though the reaction is not a practical way to remove large quantities of carbon dioxide from the atmosphere, it does provide an alternative new route, using a cheap, nonpetroleum feedstock, to make useful chemicals.
