BACKGROUND Despite its semi-commercial status, ethanol production from lignocellulosics presents many complexities not yet fully solved. Since the pretreatment stage has been recognized as a complex and yield-determining step, it has been extensively studied. However, economic success of the production process also requires optimization of the biochemical conversion stage. This work addresses t...

Networks C. A. Schweiger and C. A. Floudas1 Department of Chemical Engineering, Princeton University, Princeton, NJ 08544-5263, USA Abstract{The synthesis of optimal reactor networks using a superstructure based approach is considered. The fundamental units in the superstructure are the continuous stirred tank reactor (CSTR) and a cross ow reactor (CFR). The mathematical modeling leads to an op...

Abstract The aldol reaction of bio acetone in presence a strongly basic ion exchange resin was carried out with and without the addition water temperature range between ? 30 °C 45 °C. conversion, selectivity service time resins were investigated stirred batch reactor continuous fixed bed reactor. For experiments, both conversion increased decreasing temperature. Furthermore, to medium has posit...

In this brief, we propose a novel method based on the Taylor expansion for estimation of input delay class input-affine dynamical systems. The proposed guarantees asymptotic convergence error to zero. An application continuous stirred tank reactor system shows effectiveness method.

Continuous Stirred Tank Reactor (CSTR) is an essential focus in process control and offering a diverse range of researches in the area of chemical and control engineering. To ensure the successful operation of a continuous stirred tank reactor (CSTR), it is necessary to understand their dynamic characteristics, which ultimately enable effective control systems design. The problem of controlling...

Waste printed circuit boards (WCBs) were debrominated under hydrothermal treatment, using potassium carbonate as an alkaline additive to improve debromination efficiency (DE). Two different high-pressure reactors used: a 1-L stirred reactor, where the evolution of DE was followed over time at low CO32?/Br? ratio (1:25), and elementary 0.1-L non-stirred used find optimal parameters simplify (HTD...

The release of mine effluents can have a damaging impact on receiving water bodies. Therefore, treatment of mine waters before discharge is imperative. A novel biological SO²⁻₄ removal technology has been developed whereby the degradation/fermentation products of grass cellulose, volatile fatty acids (VFA), function as the electron donors and SO²⁻₄ as the electron acceptor. The aim of the study...
