Thesis aims to design suitable technology for biogas treatment so that its output can be used as a fully equivalent fuel for vehicles. First part introduces reader into an area of biogas treatment. Second part describes in detail chosen method, technology of membrain separation. In third part, current conditions in Czech republic were discussed. Fourth part adresses the aplication of membrane technology into existing biogas station via side-standing reaserch container. The end of the thesis is focused on selection and proper desing of blower, which will be transporting raw biogas from biogas fermenters into research container.
