Energy, fuel types gasification

Carbonaceous fuels are used throughout the world as major energy sources. They exist primarily in solid forms, or heavy liquid forms, containing significant process and environmental contaminants compared to cleaner fuels such as natural gas. Coals and biomass fuels are two of the many carbonaceous fuel types that can be effectively processed in fluidized bed reactors, and they are currently of great industrial interest for fluidized bed gasification and combustion. 

For the conversion of biomass resources into useful chemicals and bio-ener, three major process types, direct combustion, gasification and liquefaction, are effective. Among them, liquefaction for liquid transpiration fuels is, in particular, important because it is difficult to replace them with other energy forms. Thus, a study of the liquefaction of biomass is of interest. ... 

Low BTU gasification technology is commercially available for most types of biomass feedstocks and can be expected to have an impact on energy supplies by 1985. Many of these commercial processes are based on low BTU coal gasification technologies and the gas produced can best be used as fuel for supplying process heat, process steam or for electrical power generation. 

Fossil fuels such as coal, oil, gas, and all types of biomass and domestic and industrial wastes are burnt or gasihed for the conversion of energy. In Western European countries, Japan, and the United States activities are carried out for decreasing emissions of hydrocarbons, CO, NO c, N2O, NH3, SO c, dioxins, and CO2 from the combustion and gasification of fossil fuels and the burning of biomass and wastes. 

Usually after the carbon black synthesis a cooling step is apphed to stop the growth of the particles. Various types of oils are used as raw materials in the different industrial processes. Some processes apply natural gas as fuel to produce the required energy for the cracking reaction. The carbon black types, which are produced based on the particle combustion technology, are lamp black, furnace black, the Super /ENS ACO products, and the carbon black produced as by-products of the shell gasification process. ...
