Ethylene oxide is produced by the catalytic oxidation of ethylene: C2H4 (g) + 1/2 O2 (g) --> 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 components: C2H4 and O2 are recycled to the reactor, C2H4O is sold, and CO2 and...

Synthetically produced ethanol is an important industrial commodity used for various purposes including: as a solvent (especially for substances intended for human contact or consumption); in coatings, inks, and personal-care products; for sterilization; and as a fuel. Although a great deal of attention has been given to the production of ethanol by fermentation of sugars, industrial ethanol is a petrochemical synthesized by the hydrolysis of ethylene: C2H4 (9) + H20 (v) = C2H5OH (v) Some of the product is converted...

Question 1 The following gas phase reaction produces ethanol (C2H5OH) by catalytic hydrogenation of acetaldehyde (CH3CHO). The reaction reaches equilibrium at a temperature of T= T(N) and a pressure of 3 bar: CH,CHO (g)+ H2 (g)C,H,OH (g) The reactive system initially contains 1.5 moles of Hydrogen (H2) for each mole of acetaldehyde (CH3CHO). The mixture is assumed to be an ideal gas. T(N) is the temperature corresponding to the student number as shown in the attached...

(Multiple reactions with heat effects). Styrene can be produced from ethylbenzene by the following reaction: 2 H styrene ne ethylbenze + ↔ (1) However, several irreversible side reactions also occur: ethylene benzene ne ethylbenze + → (2) methane toluene H ne ethylbenze 2 + → + (3) [J. Snyder and B. Subramaniam, Chem. Eng. Sci., 49, 5585 (1994)]. Ethylbenzene is fed at a rate of 0.00344 kmol/s to a 10.0- m 3 PFR reactor along with inert steam at a...

Quantitative: In the 1950s liquid hydrogen was considered as a fuel for a new type of aircraft being developed, the SR-71 Blackbird (shown in Figure 1). Figure 1: The SR-71 Blackbird Early research on the project focused on which fuel to use for the Blackbird. Pratt & Whitney had a J-57 engine that was designed for kerosene and being considered for implementation on the Blackbird. The J-57 only took 5 months to convert to running on liquid hydrogen, however tests...
