Question

Which of the following crude oil will produce the best quality of energy-rich fuels?

• A. Heavy crude oil
• B. Medium crude oil
• C. Light crude oil
• D. All will produce the same quality

Answer 1

The correct option is C Light crude oil

The lighter grades of crude oil produce the best yields of these products, but as the world's reserves of light and medium oil are depleted, oil refineries are increasingly having to process heavy oil and bitumen, and use more complex and expensive methods to produce the products required.
