BPE undergo hydrolysis in HTLW, and main products were phenol and benzyl alcohol with the minimum selectivities of 75.7% and 82.8%, respectively.
In optimization, minimum methane selectivity is obtained as an aim.
With fixed membrane permeability, along with the product purity, the minimum cost selectivity is found.
From experiments in three different sizes of channel: 2 mm × 2 mm, 3 mm × 3 mm, and 5 mm × 5 mm (at P = 8 bar, T = 388 K, with liquid and gas flows L = 3.2 kg m−2 s−1, G = 1.35 × 10−2 kg m−2 s−1), it was shown that in a short 10 cm length of channel, a product yield up to ca. 29% (with minimum 99.5% selectivity) could be obtained.
The energy envelope curve can provide a guideline from an energy perspective to determine the minimum required membrane selectivity in membrane process designs to compete with conventional separation processes, such as distillation.
Inadequacies in the ability to administer therapeutic agents with high selectivity and minimum side effects largely account for the discrepancies encompassing cancer therapies.
Although suppressing oxygen partial pressure was found to increase ethylene selectivity, a minimum oxygen concentration is required in order to maintain the catalyst in oxidized state.
Compared with the traditional methods, adsorption has received specific attention because it has significant advantages including high efficiency, easy handling, high selectivity and minimum production of chemical or biological sludge (Randelovic et al. 2012; Gupta et al. 2007a, b, 2009).
It was found that minimum noise and better selectivity were obtained upon using 10 μg/mL of CEF spectrum and 8 μg /mL of MOX spectrum as a divisor.
These studies involve catalyst design for reforming of ethanol as well as determining the optimum operating conditions for maximum hydrogen selectivity and minimum energy requirement for the reforming reaction.
