Effect of Zeolitic Imidazolate Framework Topology on the Purification of Hydrogen from Coke Oven Gas
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...
