Q. Producer gas is obtained by

(A) passing air through red hot coke

(B) thermal cracking of naphtha

(C) passing steam through red hot coke

(D) passing air and steam through red hot coke

Ans: passing air and steam through red hot coke

Producer gas is obtained by passing a mixture of air and steam through red-hot coke. The process is known as the gasification of coke. In this process, coke (carbon) reacts with a combination of oxygen from the air and hydrogen from the steam to produce producer gas, which mainly contains carbon monoxide (CO), hydrogen (H2), and nitrogen (N2). Producer gas was historically used as a fuel for various industrial applications, such as heating and power generation.
