Carbon Dioxide as Chemical Feedstock Michele Aresta
Publisher:

Conventional greenhouse control methods use chemical or physical solvents to separate carbon dioxide (CO2) from various gas species generated from the fossil fuel conversion, which results in significant parasitic energy losses. Achieve dramatic lower emissions levels, as the syngas produced is at higher temperature and pressure, which allows for easier removal of sulfur (SOX), nitrous oxides (NOX) and lends itself to efficient carbon dioxide (CO2) removal as well. "We can take carbon dioxide directly from the atmosphere and turn it into useful products like fuels and chemicals without having to go through the inefficient process of growing plants and extracting sugars from biomass." . €�The process doesn't require high temperatures or exotic chemicals,” said Rau. Here is a link to article on USC News. 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. It is possible to make build an organism from scratch that can have multiple artificial amino acid dependencies so it can't survive without feed stock. 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. They accounted for 81% of the global energy supply in 2010, and unless aggressive new measures are taken to reduce CO2 emissions, they are projected to retain a 75% share in 2035.1 Carbon Capture and Storage (CCS) is the only .. Proceedings of the National Academies of Sciences. Gasification is a process through which coal can be transformed into power, chemicals, hydrogen and transportation fuels, capturing the resulting carbon by-product from the coal for sequestration or for enhanced oil recovery. Several companies are pursuing the idea / concept of thermochemical and electrochemical conversion of CO2 into chemical feedstock or polymers. Large-scale electrolysis is something that is already available, he said. €�It uses commonly available materials. It's too bad, too, as the chemical industry has actually been one of the better industries from an emissions perspective. 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. 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.

In addition, the researchers hope to find a low-cost method of turning the CO2 into methanol, a fuel and a chemical feed stock. Hal Harvey writes about an important caveat in the work:.
