Black and White Oils Partial Oxidation on Pilot Plant Unit
Hanika, Jiří ; Lederer, J. ; Nečesaný, F. ; Nečesaný, F., jr. ; Poslední, W. ; Tukač, V. ; Veselý, Václav
Based on pilot plant experiments the paper describes basic parameters influence on selectivity of partial oxidation process. The gaseous product composition was very similar to Unipetrol RPA plant process parameters operating by Shell technology. During pilot plant tests also soot was present in the raw gas. The soot amount was slightly higher because the pilot plant reactor operated at temperature below 1200 °C, see4. Investigation of physicochemical properties samples of soot is under way now and results will be presented in another our paper. At present another effort is focused to numerical POX process model formulation. Comparison of experimental data and simulation results will be reported later.

Sorbents for Phenol Removal from Contaminated Waters
Papežová, Barbora ; Hanika, Jiří ; Matějková, Martina ; Šolcová, Olga
Nowadays, contamination of underground and surface water by various pollutants is serious environmental problem. Phenol and phenolic compounds belong to the most common organic pollutants. Huge sources of contamination are industrial waste waters (from chemical, rubber, pharmaceutical, petrochemical and other industry), which are necessary to purify. Various techniques (oxidation, enzymatic purification, sorption, photocatalysis, or their combination) are used for water treatment. This study is focused on suitable technique for phenolic compounds removal from contaminated waters.

CFD Model of HDS Catalyst Tests in Trickle-Bed Reactor
Tukač, V. ; Prokešová, A. ; Hanika, Jiří ; Zbuzek, M. ; Kubička, D.
The goal of this study was to evaluate hydrodynamic influence on experimental HDS catalyst activity measurement carried out in pilot scale trickle-bed reactor. Hydrodynamic data were evaluated by RTD method in laboratory glass model of pilot reactor. Mathematical models of the process were formulated both like 1D pseudohomogeneou and 3D heterogeneous ones. The aim of this work was to forecast interaction between intrinsic reaction kinetic, hydrodynamics and mass transfer.

Hydrogen or Soot ?: Partial Oxidation of High-Boiling Hydrocarbon Wastes
Lederer, J. ; Hanika, Jiří ; Nečesaný, F. ; Poslední, W. ; Tukač, V. ; Veselý, Václav
This paper is focussed to research of the influence of process parameters of partial oxidation like quality of hydrocarbon raw materials, which differed in their stock properties (especially the boiling point and viscosity), on the composition of output gas (selectivity of the process) and also on the formation extent of soot which can be used as an excellent and valued sorbent CHEZACARB(™) and/or filler in rubber industry, e.g. for automotive tires. The effects of steam flow rate and oxygen to raw material feed rate ratio is discussed as well.
