Petroleum products can also be made from coal, natural gas, and biomass. Products made from crude oil. After crude oil is removed from the ground, it is sent to a refinery where different parts of the crude oil are separated into useable petroleum products. These petroleum products include gasoline, distillates such as diesel fuel and heating ...
A coal refinery or coproduct system is defined as ''a system consisting of one or more individual processes integrated in such a way as to allow coal to be processed into two or more products supplying at least two different markets" (DOE, 1991).

Dec 05, 2018· Coal occurs after living materials like plants and animals collect in a swampy region decay and degrade by decomposition of microorganism resulting in solid products, which can produce heat. On the other hand, charcoal occurs after plats, especially woods and plant trumps are exposed to heat and a limited supply of oxygen.
Carbon Dioxide Emission Factors by Coal Rank and State of Origin. The (arithmetic) average emission factors obtained from the individual samples (assuming complete combustion) (Table FE4) (10) confirm the long-recognized finding that anthracite emits the largest amount of carbon dioxide per million Btu, followed by lignite, subbituminous coal, and bituminous coal.
