Learn how to set up and solve the five COMSOL Multiphysics models featured in the textbook Elements of Chemical Reaction Engineering by H. Scott Folger.
it is known that, differently from what Aristotle postulated, the matter is not made of the essential substances water, fire, earth, and air. However, his philosophical work in questioning the origin of matter formed the basis for the discussion of the chemical elements and their combinations. ...

The law of multiple proportions states that if two elements A and B combine together to form more than one compound, then thedifferent masses of A that combine with a fixed mass of B are in a simple ratio. This follows from the principle that in compounds, atoms combine in a simple ...
FTIR analysis allows chemists to use very small samples of a substance to identify and quantify its components. READ MORE Gas Chromatography Mass Spectroscopy GC/MS is a combination of two advanced analytical techniques which allow for the identification and precise quantification of volatile and semi...
In college, I was taught an elegant theory of chemical combination based on excess electrons going into holes in the orbital shell of a neighbouring atom. But what about diatomic compounds like oxygen gas? Don't ask; students aren't ready to know. In physics, in biology, in any other sci...
) and autothermal reforming (ATR, combination of Eqs. 1, 3, 4) have also been commercialized for syngas production, which is usually followed by WGS reaction for H2 enrichment and CO2 separation for H2 purification. However, the associated air separation unit (ASU) and acid gas removal ...
