• False
• True
False
In petroleum refining, which process improves the octane rating of gasoline by converting low-octane hydrocarbons
Catalytic reforming
The gasoline pool in a refinery consists of multiple streams blended to meet fuel specifications.
Group of answer choices
False
True
True
The gasoline pool in a refinery consists of multiple blending streams, such as fluid catalytic cracking (FCC) gasoline, reformate, alkylate, isomerate, and straight-run gasoline. These streams are blended to meet fuel specifications, including octane rating, volatility, sulfur content, and environmental regulations.
What is the primary reason vacuum distillation is used in refineries?
Group of answer choices
It allows for the separation of high-boiling-point components without excessive thermal degradation.
It improves the octane rating of fuels.
It increases the yield of gasoline by breaking down heavy fractions.
It reduces energy consumption by operating at lower temperatures.
It allows for the separation of high-boiling-point components without excessive thermal degradation.
