The aim of this work was to analyse the applicability of electrical conductivity sensors for on-line monitoring the start-up period of an anaerobic fixed-bed reactor. The evolution of bicarbonate concentration and methane production rate was analysed. Strong linear relationships between electrical conductivity and both bicarbonate concentration and methane production rate were observed. On-line...

In this research, the thin films of N-S doped titanium dioxide (TiO2) were successfully prepared by simple sol-gel method in the presence of tetrabutylorthotitanate as a starting reagent. Furthermore, titanium dioxide (TiO2) was functionalized with thiourea. Furthermore, N-S doped titanium dioxides (NSTO) were fixed on glass balls by glass balls fixed-bed reactor system. Besides, the effect of ...

Stratégia adaptívneho riadenia pre triedu nelineárneho rozvoja bioprocesov This paper presents the control problem of a class of propagation bioprocesses that are carried out in fixed bed reactors. Since the dynamics of these processes are described by partial differential equations, in order to obtain useful models for control purposes, a possible method consists of approximation of their infi...

The study aims to compare three sewage biological treatment methods- activated sludge, moving bed biofilm reactor (MBBR), and fixed reactor. sludge method is the most used in ship treatment. However, carrier methods, such as MBBR reactors, have improved their effectiveness with industrial wastewater, being considered industrial. An experiment was carried out untreated samples, chemical oxygen d...

Sugarcane bagasse was pyrolyzed using a laboratory fixed bed reactor to produce char and its by-product (pyrolysis liquid). The pyrolysis experiments were carried out different temperatures (400°C 500°C), heating ... | Find, read cite all the research you need on Tech Science Press
