Petelyse-PET Recycling
Veselý, Václav
Chemical recycling of PET to terephtalic acid and ethyleneglycol is carried out in two stages through alkaline glykolysis and subsequent hydrolysis. The product of hydrolysis is elektrolicically further separated into terephtalic acid suspense and alkaline glykol solution. Crystallic terephtalic acid separates from the suspense and once washed is dried. Vacuum istilation is applied to get ethylenglycol.

Recyklace PET lahví
Veselý, Václav ; Hanika, Jiří
Chemical PET recycling to therephtalic acid and ethylenglycol is carried out through alkaline hydrolysis and subsequend electrodialysis. The alkaline glykol solution is recur to the hydrolysis. Crystallic therephtalic acid is separated from suspense and is washed and dried. Vakuum destilation is applied to get ethylenglycol.

Principles of Gasification Technology; Literature Review
Hanika, Jiří ; Jiřičný, Vladimír ; Punčochář, Miroslav ; Veselý, Václav ; Vosecký, Martin
The present review deals with gasification technologies in relation to rape grouts, which is relevant fuel at the project. Fundamentals about several gasification technologies, such as in fixed-bed, fluidized-bed and entrained flow, are discussed. Moreover, an overview of gasification units which are based on the relevant technologies is stated.

Petelyza-Chemical PET Recycling
Veselý, Václav
Chemical recycling of PET is carried through alkaline hydrolysis. The produkt is salt of terephtalic acid, which is electrolytically furthet separated into PTA and alkaline glykol solution. Vakuum destilation is applied to get etylenglycol.
