Match each industrial fuel gas or coal distillation product in Column A with its corresponding chemical composition or production method in Column B.
- Water gasA mixture of carbon monoxide and hydrogen () formed by passing steam over incandescent coke.
- Producer gasA mixture of carbon monoxide and nitrogen () formed by passing air over red-hot coke.
- Coal gasA gaseous fuel mixture containing mainly hydrogen, methane, and carbon monoxide obtained during the destructive distillation of coal.
- Coal tarA dark, viscous liquid byproduct of coal distillation rich in aromatic hydrocarbons such as benzene and phenol.
Answer
Water gas matches with the mixture of carbon monoxide and hydrogen () formed by passing steam over incandescent coke; Producer gas matches with the mixture of carbon monoxide and nitrogen () formed by passing air over red-hot coke; Coal gas matches with the gaseous fuel mixture containing hydrogen, methane, and carbon monoxide obtained during coal distillation; Coal tar matches with the dark viscous liquid byproduct rich in aromatic hydrocarbons.
Water gas is defined as a mixture of carbon monoxide and hydrogen gas made from steam and incandescent coke. Producer gas is defined as a mixture of carbon monoxide and nitrogen gas made from air and red-hot coke. Coal gas is the fuel mixture () obtained from coal carbonization. Coal tar is the thick, dark liquid distillate containing aromatic hydrocarbons produced alongside coke and coal gas.
