Biomass Energy National Geographic Society

The most common biomass materials used for energy are plants, wood, and waste. These are called biomass feedstocks. Biomass energy can also be a nonrenewable energy source. Biomass contains energy first derived from the sun: Plants absorb the sun's energy through photosynthesis, and convert carbon dioxide and water into nutrients (carbohydrates).

Gasification Wikipedia

Gasification is a process that converts biomass or fossil fuelbased carbonaceous materials into gases, including as the largest fractions: nitrogen (N 2), carbon monoxide (CO), hydrogen (H 2), and carbon dioxide (CO 2).This is achieved by reacting the feedstock material at high temperatures (typically >700 °C), without combustion, via controlling the amount of oxygen and/or steam present in ...

Processing of Timber: Top 4 Steps of Timber Processing

Following are the four steps of timber processing: 1. Felling of Trees 2. Seasoning of Timber 3. Conversion of Timber 4. Preservation of Timber. Step # 1. Felling of Trees: To get timber, the trees are knocked down or cut down or caused to fall to the ground. This is known as the felling of trees. The important facts to be remembered in connection with felling of trees are as follows: (i) Age ...

The Origin and Classification of Coal | SpringerLink

The process of transforming vegetable matter into coal usually occurs in two main steps: the biochemical and the physicochemical stage of coalification (Stach et al. 1982; Diessel 1992). In the biochemical stage, organisms initiate and assist in the chemical decomposition of vegetal matter, and in its conversion into peat and brown coal.

The Coalification Process | SpringerLink

Abstract. The transformation of vegetable matter into peat and coal is commonly regarded as proceeding in two steps, called the biochemical and physicochemical stage of coalification (Stach et al. 1982), respectively. Other terms, such as "first and second phase" (Mackowsky 1953), or "diagenetic and metamorphic stage" (Teichmüller 1962 ...

Carbonization Wikipedia

Carbonization is a pyrolytic reaction, therefore, is considered a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and isomerization . Carbonization differs from coalification in that it occurs much faster, due to its reaction rate being faster by many orders of magnitude.

PDF Fossil Energy Study Guide: 300 million years ago

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.

Due to high pressure and temperature and the absence of air, the wood of the buried forest plants and trees slowly got converted into coal. The slow process by which the dead plants buried under the Earth have become coal is called as carbonisation. Since coal was formed from the remains of the plants, it is called a fossil fuel.
