  • Question 1
    30 seconds
    Q.

    How adsorption process take place?

    answer choices

    separation through liquid and gases

    separation through solid

  • Question 2
    30 seconds
    Q.

    In adsorption from liquid process, choose what type of adsorbent usually use in this unit.

    answer choices

    Carbon

    Zeolite

    Silica

    Activated carbon

  • Question 3
    30 seconds
    Q.

    Definition of irreversible adsorption.

    answer choices

    Amount of adsorbed is proportional to the concentration in the fluid.

    low solid loadings are obtained and because it leads to quite long mass-transfer zones in the bed.

    Amount of adsorbed is independent of concentration down to very low values

    answer choices

    liquid sorption

    ion exchange

    chemisorption

    Physisorption

    granular

    porous material

    high surface area to unit mass

    high unit mass to surface area

  • Question 6
    30 seconds
    Q.

    Choose importance of regeneration to adsorbent.

    answer choices

    removal of adsorbent

    removal of unknown particles

    removal of adsorbates

    reduce activation energy of reaction

  • Question 7
    30 seconds
    Q.

    Define adsorption isotherm.

    answer choices

    equilibrium relationship between the concentration in the fluid phase and the concentration in the adsorbate particles

    equilibrium relationship between the concentration in the fluid phase and the concentration in the adsorbent particles

    equilibrium relationship between the concentration in the gas phase and the concentration in the adsorbent particles

    equilibrium relationship between the concentration in the gas phase and the concentration in the adsorbate particles
