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 diselenide Carbon diselenide Carbon diselenide is an inorganic compound with the chemical formula CSe. It is a yellow-orange oily liquid with pungent odor. It is an analogue of carbon disulfide (CS). This light-sensitive compound is insoluble in water and soluble in organic solvents. Carbon diselenide is a linear molecule with D symmetry. It is produced by reacting selenium powder with dichloromethane vapor near 550 °C. It was first reported by Grimm and Metzger, who prepared it by treating hydrogen selenide with carbon tetrachloride in a hot tube. Like carbon disulfide, carbon diselenide polymerizes under high pressure. The structure of the polymer
