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
Carbon–hydrogen bond thought earlier. The C−H bond in general is very strong, so it is relatively unreactive. In several compound classes, collectively called carbon acids, the C−H bond can be sufficiently acidic for proton removal. Unactivated C−H bonds are found in alkanes and are not adjacent to a heteroatom (O, N, Si, etc.). Such bonds usually only participate in radical substitution. Many enzymes are known, however, to affect these reactions. Although the C−H bond is one of the strongest, it varies over 30% in magnitude for fairly stable organic compounds, even in the absence of heteroatoms. The C−H unit is formally named
