All of the following are reactor types except (a) Fluidized Bed (b) Packed Bed (c) Continuous Stirred Tank (d) Grinding Bed Q39. In chemical reactors, a catalyst is (a) A high tech agitator that accelerate the reactor (b) A support material that prevent leakage (c) A material that accelerate the rate of reaction without itself undergoing any permanent chemical change (d) A material that accelerate the rate of reaction by reacting with one of the feed components

Explanation / Answer

Question 35.

In extraction we have solute in the liquid phase and we use another liquid whose affinity to absorb solute is greater than the primary liquid

Hence the answer is option A) all the components are in liquid phase

Question 36)

Scrubbers are used to remove on the solute from the gas stream by absorbing it in another stream

Hence the correct answer is option d) separation device

Question 37)

The streams coming out of extraction process are names as Raffinate phase which is rich in solute in Extract phase which is rich the solvent

Hence the correct answer is option b) raffinate, extract

Question 38)

Grinding bed is a kind of mechanical operation and involves no reaction

Hence the answer is option d) Grinding bed

Question 39)

A catalyst is something that doesn't itself gets reacted in the process but provides the necessary activation energy for the reaction to get carried out

Hence the answer is option c) a material that accelerates the rate of reaction without itself undergoing any permanent chemical change.
