In the 1950s, when Calvin carried out his work, little was known about the details of photosynthesis and the idea that carbon dioxide was the feedstock for making plants' sugary foodstuffs wasn't widely accepted. What if the chemical industry could use the carbon dioxide produced by power plants to create these and many other products? The producer of “ Lycra” and other famous Using industrial waste gas as feedstock, LanzaTech's technology is not limited in resources as could be food crops and associated lad produced resources. 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 . Here is a link to article on USC News. Thus, in a subsequent step, one or more chemical reactors are used to largely convert CO into carbon dioxide (CO 2) via the water-gas shift (WGS) and preferential oxidation (PrOx) or methanation reactions, which are described later. Because carbon dioxide (CO2) gas is a freely available resource, there are concerted efforts worldwide to convert this molecule into 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. 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. It is a variation of pyrolysis, and, therefore, is based upon partial oxidation of the feedstock material into a mixture of hydrogen, methane, higher hydrocarbons, carbon monoxide, carbon dioxide, and nitrogen, known as “producer gas” [37]. Alternatively, instead of storage, the captured CO2 could be used as a chemical feedstock to produce carbon-based fuels and chemicals when combined with renewable hydrogen produced using additional wind energy. Hal Harvey writes about an important caveat in the work:. In addition, the researchers hope to find a low-cost method of turning the CO2 into methanol, a fuel and a chemical feed stock. The nylon world leader, Invista from Wishita, Kansas, USA, and the bio-technology specialist LanzaTech signed a joint development agreement to convert carbon monoxide waste into butadiene and other chemical feedstocks. Excess atmospheric CO2 as environmentally beneficial seawater bicarbonate or carbonate,” Rau said.
