Which of the following is not obtained as a fraction during the refining of petroleum ?

Options

A. Kerosene
B. natural gas
C. lubricating oil
D. bitumen

Answer

To solve the question "Which of the following is not obtained as a fraction during the refining of petroleum?", we can follow these steps:

### Step 1: Understand the refining process of petroleum
- Petroleum refining is an industrial process that transforms crude oil into useful products. This process involves separating the crude oil into different fractions based on their boiling points.

### Step 2: Identify common fractions obtained from petroleum refining
- Common fractions obtained during the refining of petroleum include:
- Gasoline
- Diesel fuel
- Kerosene
- Lubricating oil
- Bitumen
- Heating oil
- Liquid petroleum gas (LPG)

### Step 3: Analyze the options given in the question
- The question asks which option is NOT obtained as a fraction during the refining of petroleum. We need to evaluate each option provided.

### Step 4: Evaluate each option
- **Option A**: Gasoline - This is a fraction obtained from refining.
- **Option B**: Natural gas - This is not obtained from the refining of petroleum; it is a separate fossil fuel found in gas fields.
- **Option C**: Lubricating oil - This is a fraction obtained from refining.
- **Option D**: Bitumen - This is also a fraction obtained from refining.

### Step 5: Conclusion
- Based on the evaluation, the correct answer is **Option B: Natural gas**, as it is not obtained as a fraction during the refining of petroleum.

### Final Answer:
Natural gas is not obtained as a fraction during the refining of petroleum.
