Potential Hydrogen Production by Partial Oxidation of Waste Biomass
Tukač, V. ; Tomešová, Z. ; Hanika, Jiří ; Veselý, Václav ; Lederer, J. ; Nečesaný, F.
Using process simulator AspenPlus equilibrium composition of biomass (rape waste) partial oxidation product was calculated. Problem was solved by Gibbs‘ function minimization for model reaction components. Attention was paid also to partial incineration of rape waste. Experimental results were in good agreement with model simulation.
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.
Development of the Distiller Grains
Veselý, Václav
The development of distiller grains from etanol production. Technological process and analysis of products. Processes are combustion, use of grains for snímal, pyrolysis and partial oxidation for hydrogen and syngas production.
Report of Remediation of Unground Water by Zero Ialen Iron
Veselý, Václav ; Červenka, J.
The measurement of kinetic parametrs for underground water contaminated by perchlorethylene. Cast iron was the best material with high eficiency. The column tests was practised. Kinetic model of consecutive reaction was used for design of continuous reactor with zero valent iron bed.
A New Method of PET Botles Chemical Recycling
Veselý, Václav ; Hanika, Jiří ; Čech, B.
This article deals with a new method of PET botles chemical recycling.
Principles of Gasification Technology; Literature Review and Mathematical Modelling of Biomass Gasification
Hanika, Jiří ; Jiřičný, Vladimír ; Punčochář, Miroslav ; Tukač, V. ; Veselý, Václav
The present report gives a review of patents dealing with partial oxidation of solid fuels, particularly rape grouts. Besides, mathematical model of partial oxidation of solid fuels in entrained flow gasifiers is proposed and carried out in Aspen plus software. Results of mathematical modelling are given, namely performance of the generator in the dependence of varying input parameters is shown
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.
Thermodynamics of Biowaste and Refinery Waste Partial Oxidation
Tukač, V. ; Hanika, Jiří ; Veselý, Václav ; Lederer, J. ; Nečesaný, F.
Complex chemical equilibrium of biowaste gasification by partial oxidation in presence of water steam was simulated using AspenPlus software. Both waste from colza oil production and visbreaking waste were investigated from the hydrogen/carbon oxide mixture formation point of view. Parametric sensitivity of product compositon on reaction temperature was discussed in the study.
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.
