Converting existing coal plants to run on natural gas offers a pragmatic pathway for significantly curbing emissions from power generation. Pound for pound, natural gas emits nearly 50% less carbon dioxide when burned compared to coal. Retrofitting coal plants to utilize gas combustion turbines or combined cycle systems can thus provide ...

The Process of conversion of wood into coal by biochemical process is known as Carbonization. Coal burns cleaner than wood burning coal was easier because coal burned longer than wood. Carbonization is the term for the conversion of an organic substance into carbon or a carboncontaining residue through pyrolysis or destructive distillation. It ...

Th e process of converting coal into electricity has multiple steps and is similar to the process used to convert oil and natural gas into electricity: 1. A machine called a pulverizer grinds the coal into a fi ne powder. 2. Th e coal powder mixes with hot air, which helps the coal burn more effi ciently, and the mixture moves to the furnace. 3.

Carpita (pictured) and Maureen McCann have developed and refined methods for efficiently converting cellulosic biomass into fuels. Their findings could be used with geneediting technology to make fuel from biomass sorghum, seen here, or other bio feedstock plants.

Coals are classified into three main ranks, or types: lignite, bituminous coal, and anthracite. These classifications are based on the amount of carbon, oxygen, and hydrogen present in the coal. Coals other constituents include hydrogen, oxygen, nitrogen, ash, and sulfur. Some of the undesirable chemical constituents include chlorine and sodium.

In pursuant to the European Union's target of 20% renewable energy use by 2020, many European power producers have converted, or are in the process of converting, coalfired power plants to utilize wood pellets in lieu of coal (Goetzl, 2015). Wood pellets offer a consistent, uniform supply of biomass, in which the pelleted form yields double ...

The production of methanol only from coal has an estimated efficiency of 41 to 55 percent; but if methane and coal liquids are produced simultaneously, the overall process efficiency can climb to 75 percent. Waste and wood can also be used as energy sources. Conversion from these sources to methanol is likely to be somewhat less efficient ...
