Importance of cracking of hydrocarbons
WitrynaThe Importance of Hydrocarbons. Hydrocarbons, organic chemical compounds of carbon and hydrogen molecules, are one the world’s most crucial energy resources, derived from petroleum, natural gas, and coal. They are utilized as fuels, lubricants, electrical power generation, heating, and as raw materials to make plastics, fibers, … Witryna20 lip 2016 · Hydrocarbons are in fact the main source of hydrogen gas. According to Wikipedia, 95% of all hydrogen is produced by the steam reforming reaction: C H X 4 ( g) + H X 2 O ( g) 3 H X 2 ( g) + C O ( g) This is a very important industrial process which has been studied in depth. It is done at very high temperatures (~1000 °C) and under …
