Diffusion and adsorption of linear and branched alkanes in zeolites

Branched hydrocarbons are preferred to linear hydrocarbons as ingredients in petrol, as they enhance the fuel octane number. By catalytic isomerisation linear hydrocarbons are converted into branched hydrocarbons, then it becomes necessary to separate the mixture. A variety of zeolites may be used for this purpose, either on thermodynamics or...
