Carbon Dioxide as Chemical Feedstock Michele Aresta

In the former case CO2 is treated as a valuable chemical feedstock. While shale gas offers competitively priced feedstock for certain chemicals, it also opens up opportunities to develop bio-based chemicals. Less production of other chemicals resulting from shale gas feedstock leaves a gap for bio-based chemicals However, they also provide an unrivalled opportunity to reduce oil dependence and carbon dioxide (CO2) emissions. €�But the process also would produce a carbon-negative 'super green' fuel or chemical feedstock in the form of hydrogen.” Most previously described chemical methods of atmospheric carbon dioxide capture and storage are costly, using thermal/ mechanical procedures to concentrate molecular CO2 from the air while recycling reagents, a process that is cumbersome, inefficient and expensive. 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. From 1960 the switch from coal gas (a mixture of hydrogen, carbon monoxide and methane, manufactured from coal) to natural gas (naturally occurring methane) for use in homes and industry all but killed off the remaining coal tar industry. Thermo Scientific Orion 9502BNWP carbon dioxide ISE; 75cm cable. Note: It will be interesting to see how the economics of such as the Martin & Kubic process compare to CCS [carbon capture and sequestration]. This requires less energy per ton of CO2 than most other electrochemical conversion pathways. Carbon dioxide ion selective electrode (ISE) measures carbon dioxide (CO2) … What's in the Box? This sticky black by-product of the coal gas and coke industries was a major feedstock for the chemical industry from the 1850s, but its use declined after 1920 with the rise of the petrochemical industry.
