  • coal gasification

    coal gasification is the process of producing syngas–a mixture consisting primarily of carbon monoxide co , hydrogen h 2 , carbon dioxide co 2 , natural gas ch 4 , and water vapour h 2 o –from coal and water, air and/or oxygen. historically, coal was gasified to produce coal gas, also known as 'town gas'. coal gas is combustible and .

  • fischer–tropsch process

    coal-based fischer–tropsch plants produce varying amounts of co 2, depending upon the energy source of the gasification process. however, most coal-based plants rely on the feed coal to supply all the energy requirements of the fischer–tropsch process. feedstocks: gtl. carbon monoxide for ft catalysis is derived from hydrocarbons.

  • steam reforming

    steam methane reforming smr and autothermal reformer atr are two industrial examples of the primary and secondary reformers, respectively. on the other hand, the process of combined reforming utilizes both of primary and secondary tools for production of synthesis gas, as it is commonly practiced in ammonia manufacturing.

  • grootegeluk coal mine

    the grootegeluk coal mine is an open cast coal mine within the waterberg coalfield of the limpopo province of south africa. it is operated by exxaro.the mine is 25 kilometres 16 mi from lephalale, and employs 2,000 people.

  • stamicarbon

    stamicarbon is the licensing and ip center of maire tecnimont spa which licenses technology for manufacturing urea as well as provide follow-up services designed to ensure the best possible operation of the urea plant throughout its working life. stamicarbon is based in sittard-geleen.

  • coal

    coal can be converted directly into synthetic fuels equivalent to gasoline or diesel by hydrogenation or carbonization. coal liquefaction emits more carbon dioxide than liquid fuel production from crude oil. mixing in biomass and using ccs would emit slightly less than the oil process but at a high cost.

  • stamicarbon

    dsm created stamicarbon for the purpose of managing its patent portfolio and licensing its technology. in 1947 dsm was primarily a coal mining company and initially stamicarbon was responsible for selling coal preparation plant technology. the company's name reflects its origin: 'stami' from 'state mines' and 'carbon' coal .

  • bergius process

    typically the coal should be <10% ash by weight. the hydrogen required for the process can be also produced from coal or the residue by steam reforming. a typical hydrogen demand is 80 kg citation needed hydrogen per ton of dry, ash-free coal. generally, this process is similar to hydrogenation.

  • coal preparation plant

    sampling. sampling of coal is an important part of the process control in the cpp. a grab sample is a one-off sample of the coal at a point in the process stream, and tends not to be very representative. a routine sample is taken at a set frequency, either over a period of time or per shipment.

  • petrochemical

    some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as maize, palm fruit or sugar cane. the two most common petrochemical classes are olefins including ethylene and propylene and aromatics including benzene, toluene and xylene isomers .

  • steam reforming

    steam reforming or steam methane reforming is a method for producing syngas hydrogen and carbon monoxide by reaction of hydrocarbons with water. commonly natural gas is the feedstock. the main purpose of this technology is hydrogen production.the reaction is represented by this equilibrium: ch 4 h 2 o ⇌ co 3 h 2. the reaction is strongly endothermic consumes heat, δh r = 206 kj/mol .
