The process of producing "syngas" from coal is called:

Options

A. Coal gasification
B. Shift reaction
C. Synthesis reaction
D. Dehydration reaction

Explanation

To answer the question, "The process of producing 'syngas' from coal is called:", we can follow these steps:

### Step-by-Step Solution:

1. **Define Syngas**:
- Syngas, or synthesis gas, is a mixture primarily composed of carbon monoxide (CO) and hydrogen (H2). It is an important intermediate in the production of various chemicals and fuels.

2. **Identify the Process**:
- The process of producing syngas from coal involves breaking down coal into its gaseous components.

3. **Explain Coal Gasification**:
- The specific process used to convert coal into syngas is known as **coal gasification**. In this process, coal is reacted with steam and oxygen at high temperatures to produce syngas.

4. **Chemical Reactions Involved**:
- During coal gasification, the coal reacts with water vapor (steam) and air (or oxygen) to produce carbon monoxide and hydrogen. The general reaction can be summarized as:
\[ \text{Coal} + \text{H}_2\text{O} + \text{O}_2 \rightarrow \text{CO} + \text{H}_2 \]

5. **Conclusion**:
- Therefore, the correct answer to the question is that the process of producing syngas from coal is called **coal gasification**.

### Final Answer:
The process of producing "syngas" from coal is called **coal gasification**.
