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...

Mesoporous zeolites obtained by desilication

Zeolites are crystalline microporous materials consisting of silicon, aluminium and oxygen atoms. A unique combination of properties such as high surface area, high (hydro)thermal stability, and strong acidity, makes that zeolites are frequently used as catalysts in various (petro)chemical processes. The pores of molecular dimensions are...

Opportunities and limitations of hydrogen storage in zeolitic clathrates

The feasibility of using zeolites, and more specifically the clathrasil subgroup, for hydrogen storage has been investigated by comparing their H2 loading rate and storage capacity to the technically required values. The uptake rate and capacity are determined by means of computational modelling for a large number of clathrasil structures. It...
