Carbon Dioxide as a Form of Sequestration in Algae – Which is the Ultimate Feedstock for Biodiesel or Ethanol. The Lux report also analyzed the use of municipal solid waste and waste gases such as carbon dioxide and flue gas as potential feedstock sources. Rather than treating CO2 as waste, it can be regarded as a chemical feedstock for the synthesis of other chemicals that do not rely on a petrochemical source. The low cost and low toxicity of CO2 make it an attractive industrial chemical reagent, and the utility of CO2 is dramatically illustrated by the fact that millions of tons of CO2 are consumed per year in the industrial production of urea. Siemens is participating in a research project that is looking at ways to convert carbon dioxide (CO2) into useful chemical feedstock. In the former case CO2 is treated as a valuable chemical feedstock. "CO2 from the atmosphere provides a nearly inexhaustible carbon source for humankind." Yes, but we need energy (non-carbon energy!) to make such ideas practical and to benefit from CO2 as a chemical feedstock. 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. 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. Dow wants the ethanol as a feedstock for plastic, replacing natural gas. 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.” Dawei Wang, a research associate and one of the group's team 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. Note: It will be interesting to see how the economics of such as the Martin & Kubic process compare to CCS [carbon capture and sequestration]. Scientists at the US Department of Energy's National Renewable Energy Laboratory in Golden, Colorado, have succeeded in turning carbon dioxide into ethylene, an energy-dense fuel and most widely produced feedstock for the . The algae process from power, combustion, and other chemical projects including ethanol are therefore a means of sequestering carbon, plus, in some cases, other environmentally harmful agents, with an energy source feedstock in the form of algae generated; which could be used for both ethanol and biodiesel projects. 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 algae would be exposed to sunlight, in water mixed with carbon dioxide, and would give off ethanol and oxygen. What if the chemical industry could use the carbon dioxide produced by power plants to create these and many other products? But the use of biomass for energy generation combined with carbon capture and storage is less costly than chemical options, as long as sufficient biomass feedstock is available, the scientists point out. Riken-co2-into-catalyst While some groups search for ways to lower and store carbon dioxide (CO2) gas emissions, there are efforts worldwide to convert this molecule into a chemical feedstock.
