Carbon capture and utilization in the soil permanently. A carbon-neutral fuel can be synthesized by using the captured CO from the atmosphere as the main hydrocarbon source. The fuel is then combusted and CO, as the byproduct of the combustion process, is released back into the air. In this process, there is no net carbon dioxide released or removed from the atmosphere, hence the name carbon-neutral fuel. An example of the technology include biofuel from microalgae as discussed below. Methanol, or ethyl alcohol, is the simplest member of the family of alcohol organic compound with a chemical formula of CHOH. Methanol fuel can be
Borrowing hydrogen is a poor electrophile itself, see tosylation or Swern oxidation). The method is not limited to the preparation of amines, it can also be used to form Carbon–carbon bonds (C-C bonds). Alcohols can be temporarily converted into carbonyl compounds by the metal-catalysed removal of hydrogen. The carbonyl compounds are reactive in a wider range of transformations than the precursor alcohols and can react in situ to give imines, alkenes, and α-functionalised carbonyl compounds. The metal catalyst, which had borrowed the hydrogen, then returns it to the transformed carbonyl compound, leading to an overall process in which alcohols can be converted
