Carbon Dioxide as Chemical Feedstock Michele Aresta

The algae would be exposed to sunlight, in water mixed with carbon dioxide, and would give off ethanol and oxygen. Read the full article in Chemistry World. Dow wants the ethanol as a feedstock for plastic, replacing natural gas. The authors made ​​a big jump in chemistry. Siemens is participating in a research project that is looking at ways to convert carbon dioxide (CO2) into useful 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. However, by using seaweed as the biomass source, James Clark, and co-workers, at the University of York, UK, managed to form mesoporous material, without the need for costly processes, such as supercritical carbon dioxide drying. 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. Several companies are pursuing the idea / concept of thermochemical and electrochemical conversion of CO2 into chemical feedstock or polymers. Graphene Technologies logo Graphene Technologies has been issued a US patent (#8,420,042) for a process for atom-by-atom synthesis of graphene by the exothermic chemical reduction of carbon dioxide. €�It uses commonly available materials. This resulting solution proved highly absorbent of carbon dioxide from the air, sucking up the greenhouse gas at a rate approximately 45 times greater than a control test. Shaped mesoporous materials but also in many others. Microalgal biomass is transformed before our eyes into a valuable chemical feedstock. €�The process doesn't require high temperatures or exotic chemicals,” said Rau. The company says that The company says that using this new process allows them to produce bulk volumes of pristine, few-layer graphene platelets from inexpensive, commonly available feedstock. Large-scale electrolysis is something that is already available, he said.
