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. 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. 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. 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.

While shale gas offers competitively priced feedstock for certain chemicals, it also opens up opportunities to develop bio-based chemicals. 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. I think the concept of using CO2 as feedstock for the chemical industry is the real frontier of heterogeneous catalysis and I invite you to consider it for your future work.

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. Carbon dioxide gas may be liquefied or solidified. Riken-co2-into-catalyst While some groups search for ways to lower and store carbon dioxide (CO2) gas emissions, there are efforts worldwide to convert this molecule into a chemical feedstock. 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. 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. 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. Rather than treating CO2 as waste, it can be regarded as a chemical feedstock for the synthesis of other chemicals that do not rely on a petrochemical source. 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.
