For 1 kg of CO, calculate the hydrogen required and the resulting products for ethylene (C2H4), isopropanol (C3H8O), and pentane (C5H12) for Fischertropsch synthesis.

Homework Answers

Answer #1

Fischer-tropsch synthesis reaction is

n CO + (2n+1) H2 -------------> C2H4 + C3H8O + C5H12

Hence,

1 CO + 3 H2   --------------> C2H4 + C3H8O + C5H12

1 mol    3 mol

28 g      3x2 g = 6g

1 kg         ?

       ? = (1 kg CO/ 28 g CO) x 6 g H2

        = 0.214 kg H2

mass of H2 required = 0.214 kg H2

Therefore,

0.214 kg of H2 is required for 1 kg of CO.

Ethylene oxides is produced by the catalytic oxidation of ethylene: C2H4 (g)+ (1/2)O2---> C2H4O (g) An undesired competing reaction is the combustion of ethylene to CO2. The feed to a reactor contains 2 mol C2H4/mol O2. The conversion and yield in the reactor are respectively 25% and 0.70 mol C2H4O produced/mol C2H4 consumed. A multiple-unit process separates the reactor outlet stream component: C2H4 and O2 are recycled to the reactor, C2H4O is sold, and CO2 and H2O are discarded. The...

Ethylene glycol (C2H4(OH)2) , when dissolved in water, provides the standard ‘anti-freeze’ coolant for water-cooled engines. In order to depress the freezing point of water by 20 °C, how many grams of ethylene glycol would need to be dissolved in 15 kg of pure water? (The molal freezing point depression constant for water Kf = 1.86 K mol-1 kg and the relevant atomic masses are: C = 12g, H = 1g and O = 16g.) Note: ethylene glycol is an...

1.Consider the rotation of a hydrogen bromide-79 molecule. What is the moment of inertia in kg m2 of hydrogen bromide-79? Isotope masses to three decimal places are taken from NIST and bond lengths from wikipedia. Use the isotope mass, not the average mass. 2.Next, model the rotation of hydrogen bromide-79 as a "particle on a ring". Calculate the rotational energy difference, in cm-1, between the ml=3 and ml=4 energy levels in a hydrogen bromide-79 molecule. 3.Now model the hydrogen bromide-79...
