A process for the productionof 1,3 -butadiene results from the catalytic dehydrogenation at atmospheric pressure of 1-butene according to the reaction: C4 H8(g) →C4 H6(g) H2(g) To suppress side reactions, the 1 -butene feed stream is diluted with steam in the ratio of 10 moles of steam per mole of 1 -butene. The reaction is carried out isothermally at 798.15 K(525^∘ C), and at this temperature 33 % of the 1 -butene is converted to 1,3- butadiene. How much heat is transferred to the reactor per m

The production of 1,3 -butadiene can be carried out by the dehydrogenationof 1 -butene: C2H5CH: CH2(g) →CH2: CHCH: CH2(g) H2(g) Side reactions are suppressed by the introduction of steam. If equilibrium is attained at 950 K and 1 bar and if the reactor product contains 10 -mol- % 1,3 -butadiene, find: (a) The mole fractions of the other species in the product gas. (b) The mole fraction of steam required in the feed. | Numerade

SOLVED: Butadiene and steam (0.5 mol steam/mol butadiene) are fed to a tubular flow reactor operating at 1180°F and a constant pressure of 1 atm. The reactor is not catalytic. Considering only the reversible polymerization reaction to the dimer, determine: (a) the length of a 4-in. ID reactor required to obtain 40% conversion of butadiene at a total feed rate of 20 mol Ib/h; and (b) the space velocity in liters per hour of the feed gas (at 1180°F and 1 atm) divided by the volume of the reactor

SOLVED:1,3-Butadiene has a substantial stabilization energy, whereas ethene has none, yet attack of Br ⊕on 1,3- butadiene occurs more readily than on ethene. Explain how 1,3-butadiene can have a stabilization energy greater than ethene but still be more reactive toward reagents that donate Br^⊕.
