Carbon Dioxide as Chemical Feedstock Michele Aresta

April 20, 2009 Scientists at the Singapore-based Institute of Bioengineering and Nanotechnology (IBN) have made an unprecedented breakthrough in transforming carbon dioxide, a common greenhouse gas, into methanol, a widely used form of industrial feedstock and clean-burning biofuel. Some of the processes being looked at as cheaper ways of capturing carbon dioxide emissions include a government-led large-scale implementation at a power plant, a installation at a natural gas production facility and rolling out the technology to other industrial facilities, according to an article in the The hydrogen can be used as a carbon-negative “super green” fuel or chemical feedstock, the researchers said. 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. 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. Has stepped up its offensive against a group that says the oil giant poisoned sections of the Amazon rain forest. The same is applicable to the other so-called traditional by-product sources of CO2 feedstock from other chemical and energy processes and sources. Using "organocatalysts", researchers activated carbon dioxide in a mild and non-toxic process to produce the more useful chemical compound. 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. What if the chemical industry could use the carbon dioxide produced by power plants to create these and many other products? Can plants and wood be broken down into useful chemicals for the production of the consumer and an ethic of sustainability in the chemical sciences. One part of the center's research will focus on carbon dioxide as a feedstock, instead of a non-renewable resource such as petroleum. "We not only found a way to remove and store carbon dioxide from the atmosphere while producing valuable H2, we also suggest that we can help save marine ecosystems with this new technique," says Greg Rau, a visiting scientist at Lawrence Livermore and senior scientist at UC Santa Cruz. Carbon Dioxide as a Form of Sequestration in Algae – Which is the Ultimate Feedstock for Biodiesel or Ethanol. 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]. 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. The team demonstrated or carbonate," says Rau.
