Enzymová hydrolýza oleje z černého rybízu v superkritickém oxidu uhličitém
Sovová, Helena ; Bernášek, Prokop ; Zarevúcka, Marie
Oil conversion to free fatty acids was measured for the reaction of refined blackcurrant oil and water, both dissolved in supercritical carbon dioxide, in a continuous-flow packed-bed reactor filled with immobilised lipase Lipozyme and glass beads at 15 MPa and 40 C. The enzyme amount and the flow rate were varied. The reaction kinetics was simulated with mathematical models for plug flow and ideal mixer.
Reactions into ceramics with minor amount of carbon
Stoklasa, Jaroslav
Solutions to problems of present relatively unimportant amount of ingredients of organic substances into ceramics are treated.
Kinetics of polymer crystallization
Kratochvíl, Jaroslav ; Sikora, Antonín
Kinetics of three steps of complex crystallization of poly(N-methyldodecano-12-lactam) were studied by DCS using an Avrami model. Mechanism of respective isothermal steps involves mixed heterogeneous/homogeneous nucleation (primary melt crystallization) or missing nucleation phase (additional crystallization and recrystallization) followed by two-dimensional growth.
Mathematical evaluation of functioning of the bisphenol A reactor during the year 1998
Jeřábek, Karel
Using a mathematical model based on detailed description of the kinetics of bisphenol A synthesis were evaluated changes in the efficiency of industrial reactor in a few operations performed in Spolchemie, Ústí nad Labem during the year 1998.
