The process of production of syngas coal is quite common these days. The production of syngas from c — Hydrogen Chemistry Question

💡 Solution & Explanation

# Syngas Production from Coal Since the correct answer is **C**, the process is called **coal gasification** (or water-gas reaction/steam gasification). ## Step-by-Step Explanation: **1) Definition of Syngas:** Syngas is a mixture of carbon monoxide ($CO$) and hydrogen ($H_2$), with the general formula $nCO + mH_2$. **2) The Process:** When coal (carbon) is heated with steam at high temperature (≈1000°C), the following reactions occur: $$C + H_2O \rightarrow CO + H_2 \quad \text{(water-gas reaction)}$$ $$C + 2H_2O \rightarrow CO_2 + 2H_2$$ **3) Why it's called Gasification:** - Coal is a solid fuel - The process converts solid coal into gaseous products ($CO$ and $H_2$) - Hence the term **"coal gasification"** **4) Alternative Names:** - Water-gas production (since steam is used) - Steam gasification - The product itself is called **synthesis gas** or **syngas** **Why other options would be incorrect:** - Carbonization: heating coal in absence of air (produces coke, not syngas) - Combustion: burning coal in oxygen (produces $CO_2$ and $H_2O$, not syngas) - Coking: destructive distillation (produces different products)
