Which of the following is NOT a product of petroleum refining?
-
A.
Asphalt
-
B.
Kerosene
-
C.
Natural gas
-
D.
Lubricating oil
Correct Answer:
C. Natural gas
Explanation:
The correct answer is G (Natural gas). Petroleum refining involves separating crude oil into various components based on their boiling points. Common products of this process include asphalt, kerosene, lubricating oils, gasoline, and diesel. In contrast, natural gas is a distinct fossil fuel that is often found alongside crude oil in underground reservoirs but is not a derivative produced during the oil refining process itself. Therefore, while natural gas and petroleum are related energy sources, natural gas is considered a primary raw material rather than a refined petroleum product.
