Consider the following substances : 1. Ethanol 2. Nitroglycerine 3. Urea Coal gasification technology can be used in the production of how many of them?

Coal gasification produces syngas (hydrogen and carbon monoxide), which serves as a primary feedstock for manufacturing **Urea** (via ammonia synthesis) and can be converted into **Ethanol** through catalytic processes. **Nitroglycerine** is the incorrect option because it is typically produced by nitrating glycerol, a substance derived from fats, oils, or propylene rather than coal gasification pathways. The core concept tested is the industrial application of syngas and the chemical value chain of coal gasification products.
