The photosensitizers Rose Bengal (RB) and methylene blue (MB), when immobilized in polystyrene, were found to exhibit high antibacterial activity in a continuous regime. The photosensitizers were immobilized by dissolution in chloroform, together with polystyrene, with further evaporation of the solvent, yielding thin polymeric films. Shallow reservoirs, bottom-covered with these films, were us...

The use of membrane reactors for enzymatic and co-factor regenerating reactions offers versatile advantages such as higher conversion rates and space-time-yields and is therefore often applied in industry. However, currently available screening and kinetics characterization systems are based on batch and fed-batch operated reactors and were developed for whole cell biotransformations rather tha...

This study develops a new simulation model by ASPEN Plus for gasification integrated with water-gas shift reactors and product recovery unit hydrogen production. Timber wood waste (T&WW) as lignocellulosic biomass was also considered the input feedstock to system. Then, is applied investigate effect of two agents air mixture air-steam under different operating conditions temperature steam ratio...

The paper describes a multiobjective optimization study for industrial styrene reactors using non-dominated sorting genetic algorithm (NSGA). Several twoand threeobjective functions, namely, production, yield and selectivity of styrene, are considered for adiabatic as well as steam-injected styrene reactors. Pareto optimal (a set of equally good) solutions are obtained due to conflicting effect...

The wide use of bound enzyme coils with hexokinase and glucose-6-phosphate dehydrogenase in automated analysis for serum-glucose assay [1, 2-] demonstrates the potential of open tubular heterogeneous enzyme reactors [3] in clinical analysis. Such reactors have also been prepared with other enzymes I-4, 5] and in this paper the authors describe a continuous-flow method for uric acid assay with i...

The beha®ior of stationary and mo®ing spatially-periodic patterns in a simple crossflow reactor was simulated and analyzed for a situation in which reactant is supplied continuously along the reactor and a first-order exothermic reactor occurs. The Danck( werts boundary conditions for realistic Le and Pe ®alues. While the unbounded in) finitely long reactor is an asymptotic case used to study t...

Presented is a methodology to analyze the expected Levelised Cost Of Electricity (LCOE) in the face of technology uncertainty for AcceleratorDriven Subcritical Reactors (ADSRs). It shows that flexibility in the design and deployment strategy of an ADSR park demonstrator significantly reduces its expected LCOE. The methodology recognizes in the conceptual design a range of possible technological...

Analysis of catalytic organic transformations in flow reactors and detection of short-lived intermediates are essential for optimization of these complex reactions. In this study, spectral mapping of a multistep catalytic reaction in a flow microreactor was performed with a spatial resolution of 15 μm, employing micrometer-sized synchrotron-based IR and X-ray beams. Two nanometer sized Au nanoc...

The biodegradation of phenol, p-cresol, and phenol plus p-cresol mixtures was evaluated using Pseudomonas putida ATCC 17484 in aerobic batch reactors. Shake-flask experiments were performed separately growth medium with initial nominal concentrations (50–600 mg L−1) as well L−1). complete degradation achieved within 48 h 48–56 h, respectively, for all p-cresol. maximum cell rate (μmax,P = 0.45 ...

The kinetics of cellulose hydrolysis under extremely low acid (ELA) conditions (0.07 wt%) and at temperatures >200°C was investigated using batch reactors and bed-shrinking flow-through (BSFT) reactors. The maximum yield of glucose obtained from batch reactor experiments was about 60% for α-cellulose, which occurred at 205 and 220°C. The maximum glucose yields from yellow poplar feedstocks were...
