Match Group 1 technologies with Group 2 entries. P-Urea manufacture, Q-Coal gasification, R-Controlled release of chemicals, S-Deep hydrodesulphurization. I-Microencapsulation, II-Ultra-low sulphur diesel, III-Shale oil, IV-Prilling tower, V-Gas hydrates, VI-Gas-solid non-catalytic reaction. The correct combination is

  • AP-I, Q-V, R-II, S-VI
  • P-IV, Q-VI, R-I, S-II
  • CP-IV, Q-I, R-III, S-II
  • DP-V, Q-VI, R-IV, S-II

Explanation

Urea manufacture → prilling tower (IV). Coal gasification → gas-solid non-catalytic reaction (VI). Controlled release of chemicals → microencapsulation (I). Deep hydrodesulphurization → ultra-low sulphur diesel (II).
