This work aims to shed light on the performance of zeolitic imidazolate frameworks for hydrogen purification from coke oven gases (COG). Using molecular simulation, we model COG as a mixture six and study effect ZIF topology separation performance. To do this, compare similar structures, e.g., ZIF-8 ZIF-11, focus obtaining information that explains why they behave differently while being so sim...

A modified method for the synthesis of metallooctachlorophthalocyaninesand methods their purification based on sequential treatment with hydrochloric acid (10%) sodium hydroxide (2M), then again (10%), pyridine (O.S.C.) in 1,2,4-trichlorobenzene as a solvent is presented. As result, degree copper ion complexes was achieved, 99% versus best result using known literature 93%, cobalt purity 98% 88...

Using oxygen permeable membranes (OPMs) to upgrade low-purity hydrogen is a promising concept for high-purity H2 production. At high temperatures, water dissociates into and oxygen. The permeates through OPM oxidizes in waste stream on the other side of membrane. Pure can be obtained water-splitting after condensation. However, existing Co- Fe-based OPMs are chemically instable as result over-r...

A number of substances such as oxygen, dyes, and nitrate can act as hydrogen acceptors for xanthine oxidase (1). It has now been found that cytochrome c is also reduced by this system. Since only one other enzyme has been isolated which reduces cytochrome c (2), it was of interest to study the reaction, particularly since Ball (3) has indicated that xanthine oxidase is a flavoprotein. The activ...
