Question: Pick out the wrong statement ?

• 1. Iso-paraffin crack faster than n-paraffin.
• 2. Catalytic cracking is endothermic, but the regeneration of catalyst is exothermic
• 3. Rate of decomposition of olefins in catalytic cracking is slightly slower than the thermal cracking
• 4. None of these

Question: Choose the correct statement regarding thermal cracking ?

• 1. Moderate changes in operating temperature does not change the depth of cracking
• 2. Increased residence time results in the decreased severity of cracking
• 3. At low pressure, the yield of lighter hydrocarbons are more
• 4. Greater depth of cracking gives lower octane number gasoline

Question: Pick out the correct statement pertaining to catalytic cracking ?

• 1. With increase in the reactor pressure, octane number of gasoline decreases
• 2. With increase in the reactor temperature, gasoline yield decreases for a given conversion
• 3. Percentage conversion increases with increase in the catalyst to oil ratio
• 4. All A, B and C

Question: Pick out the wrong statement ?

• 1. Alkylation produces a larger iso-paraffin (having higher octane number) from the reaction of an olefin with smaller iso-paraffin
• 2. Catalytic alkylation processes use HF, AlCl3 & H2SO4 as Catalysts
• 3. All the alkylation processes use very high temperature (> 1000°C)
• 4. Gasoline having an octane number of 90 can be produced by alkylation process
