Coal contains about % of hydrogen compared to about 18% of in petroleum. So, coal is a hydrogen deficient compound. If coal is heated with hydrogen to high temperature under high pressure, it is converted to gasoline. There are two methods available for the hydrogenation of coal. Bergius process (or direct method)

Coal is a black rock derived from peat that is commonly used as a fuel source. It can exist in lignite, bituminous, and anthracite forms and can be broken down into synthetic fuel through the Bergius process. Additionally, coal is responsible for production of coke, which has industrial applications. Explanation: The material in question is coal.
