Identify the incorrect statement regarding the alkylation process:

Explanation

Option A is true because alkylation combines olefins with smaller iso-paraffins to generate larger iso-paraffins with improved octane numbers. Option B is correct since catalysts like HF, AlCl3, and H2SO4 are commonly used in catalytic alkylation. Option D is accurate as alkylation can yield gasoline with an octane rating of approximately 90. However, option C is false because alkylation processes typically occur at moderate temperatures, not at extremely high temperatures exceeding 1000°C.
