For Aspen dynamics input, the kinetic equation in the form of a general formula that was found in the literature – how should it be entered?
Thread Content
When performing simulations for the synthesis of low-carbon alcohols and designing kinetic reactors, the only literature available provides kinetic data for the general formula used in the synthesis of such alcohols. What should be entered in such cases?
Post the equation to take a look; as long as it’s in proper form, Aspen can be used
CH3OH+(n-1)CO+2(n-2)H2O=CnH2n+1OH+(n-1)H2O
If only ethanol, propanol, butanol, and pentanol are needed, can four equations be written, with the kinetic data for each equation being expressed using this general formula?
What I mean is to post the equations of kinetics, not the reaction equations. There are just a few forms of kinetics: either in exponential form, or in LHHW format, and so on. Aspen can handle some of these modified forms as well
The kinetic equation is r2=K2Pch3oh/(1+KwPh2o). By the way, what form should this be in: LHHW or powerlaw?
lhhw, this Aspen is available
Can the data from this kinetic equation be used separately for the synthesis of the four alcohols: ethyl, propyl, butyl, and pentyl?
The kinetic form can be the same, but the parameters are definitely different; how can the parameters of one reaction be used to replace those of another reaction? . . . .
So how is one supposed to use the dynamic equation in this general-form equation?
I’m not quite sure what you’re trying to ask. Under normal circumstances, you need to find the expression for the parameters of the kinetic equations you’ve listed, such as LnK=A+B/T+C/T^2..... and so on. In Aspen, enter the parameters A, B, C, etc., making sure to pay attention to the units. The options related to driving forces are located above the numerator, while the adsorption expressions are located below it
