The scale-up and design configurations of fluid-bed chemical reactors have evolved rapidly and empirically. An example is fluid catalytic cracking (FCC) [13]. The general fluid-bed concepts developed early. However, the correlations describing the various rate processes and other operational phenomena developed slowly because they could not easily be related back to already established data bases developed for other systems in the case of trickle-bed reactors, data developed for packed-bed absorption towers were utilized. 

A hydrocarbon is a chemical compound that contains hydrocarbon and carbon. Crude oil is a mixture of hydrocarbons that vary in size and structure from simple to complex. Much modern manufacturing is based on separating the various components in crude oil by their individual boiling points. Important applied concepts of chemical processing include distillation, catalytic cracking, hydrocracking, and alkylation.
