PURPOSE:To enhance the separation efficiency of gaseous H2 by using a separation membrane which is produced by adding diisocyanate to a polycondensation product of both pyridine-dicarboxylic acid or its derivative and dibasic acid dihydrazide. CONSTITUTION:Diisocyanate such as hexamethylene diisocyanate is ...
The usual way of getting rid of CO2 is to inject it back into a separate injection well or send it to the nearest Pepsi or Coke factory. The common way of H2 production in a refinery is by partial combustion / steam reforming of methane (yield only 35%). Unless you find a source ...

E-commerce has also driven an increase in the amounts of data that needs to be processed, stored, and retrieved. This has resulted in enormous data centers that consume huge amounts of energy – as well as mirror servers in separate locations that add to the problem. ...
CO2 does explain that rise, and explains it completely without any need for additional, as yet unknown forcings.Where models have been running for sufficient time, they have also been shown to make accurate predictions. For example, the eruption of Mt. Pinatubo allowed modellers to test the ...
How would he separate them? How can we separate a mixture of iron filings and sodium chloride? Explain how CO2 is removed during the fractional distillation of liquid air. What happens to an insoluble impurity like sand or charcoal during a recrystallization? How is i...
Method of separating carbon dioxide from carbon dioxide containing gas and combustion apparatus having function to separate carbon dioxide from the combustion gas A method of separating carbon dioxide from a carbon dioxide- containing gas is disclosed, wherein the carbon dioxide-containing gas is contac...
plastic, but not to glass. Article 44 (1) does not name single-use glass as a compatible form of packaging for deposit return schemes (DRS) – a sentiment carried over in Article 44 (3), which exempts DRS for glass, even without achieving a minimum 90% separate collection for recycling...
