Question

Please provide step by step explanation.


The liquefaction of kentucky coal number 9 was carried

out in a slurry reactor. The coal particles which were less than 200 mesh, were dissolved in a 250 degrees celsius vacuum cut of recycle oil saturated with hydrogen at 400 degrees Celsius. Consider the following reaction sequence


Coal----------Preasphaltines

Coal---------Asphaltines

Asphaltines------Presasphaltines

Preasphaltines------Alphaltines

Asphaltines------Oils


All reactions are first order. Calculate the molar flow rate of each species as a function of space time in plug flow reactor and a CSTR


Entering coal concentration= 2kmol/m^3

Entering flow rate 10dm^3/min

At 400 celsius, k1=0.12 min^-1, K2=0.046min^-1,K3=0.020min^-1,K4=0.034min^-1,k5=0.04min^-1
