Q44. In a raw materials are carefully weighed and added to a reactor. The Is are mixed and allowed to react. After a pre-determined amount of time, the reactor contents are removed (a) Packed bed reactor (b) Fluidized bed reactor (c) Batch (d) CSTR reactor Q45. The lower section of the distillation tower is referred to as (a) Rectifying section (b) Flashing section (c) Stripping section (d) Isotropic section Q46. All of the following are principles of distillation except (a) Heat increases vapor pressure (b) Vacuum decreases boiling point (c) Pressure increases boiling point (d) Forming and breaking molecular bonds Q4 7. In adsorption, certain components are removed from a mixture utilizing a material (adsorbent) (a) Liquid (b) Solid (c) Gas (d) VaporExplanation / Answer
Q 44)
solids are generally carried out and dealt in fluidized reactor where we use the concept of fluidization where solids behave like fluids.
hence the answer is option b) Fluidized reactor
Q 45 )
A distillation column is briefly divided into two section namely a rectification section where high volatile component is present in large quantity and other section known as the stripping section where in the least volatile component is present in large quantity. Rectification section is the top section of the column, whereas the stripping section is the lower end of the distillation column
Hence the answer is option c) stripping column
Q 46)
Distillation is a simple seperation process where in we vary P and T to separate the components. We do not break bonds in distillation process
Hence the answer is option d) Forming and breaking molecular bonds
Q 47)
The adsorbent is the solid on which the process occurs
Hence the answer is option b) Solid
