Gas Carbon

In Great Britain, the Imperial Chemical Industries, Ltd., has developed a fluidized coal gasification process (32) using combustion of part of the fuel with air to supply the heat necessary for the endothermic steam-carbon reaction. This procedure is divided into three steps carbonization, air-blowing, and steam-blowing. The first and third steps operate with fluidized beds, and the second with a dilute suspension. Powdered coal is fed into the carbonization vessel, where it is heated by combustion of some of the carbonization gases. The powdered char is blown into a feed hopper connected with the air-... [Pg.143]

Closures made with a liner (or wad)-type sealing system break the seal faster, thereby allowing more time to vent the carbonation gases. The technology of liners has developed significantly over recent years. This development has improved the reliability of the seal across a wide range of bottles, both glass and plastic, and offers the potential for an improved barrier in the closure. All this has meant that most closures in the soft drinks and juice market today have liners of one form or another. There are two types of liner a loose liner pushed into the cap after the cap is moulded and a moulded-in liner, which is formed at the time the closure is made. [Pg.217]

This increase in atmospheric CO2 concentration for the past 200 years is primarily a result of the increased flux of carbon gases (CO2, CO, CH4) to the atmosphere from the land because of the burning of fossil fuels and deforestation and cultivation practices of society. It is likely that land use fluxes were more important than fossil fuel sources in the 19th and early 20th century, but during much of the latter century fossil fuel CO2 releases appear to have been greater than... [Pg.556]

The reconversion of metallic calxes into the metal by heating with carbon, gases, and other substances—in modem parlance the reduction of the oxide—is the result of a combination of the phlogiston of the reagent with the calx. [Pg.11]

Chemical changes in CDOM have been measured on several scales. Most common is measurement of bulk DOC by high temperature combustion or wet oxidation [94]. Other bulk measurements include carbon gases in the form of CO and CO2. However, in recent years, compound-specific and molecular analyses have provided more detailed information on the products of CDOM photodegradation. [Pg.197]

The basic difference between the formation of sulfur and the carbon gases and its influence on the isotopic ratios of kerogen, bitumen, oil and gas lies in the chemical activity of the thermally derived fragments. Both elemental sulfur and hydrogen sulfide formed at elevated temperatures could re-react with all fractions (Stoler et al., 2003). Research on changes in both carbon and... [Pg.46]

Coal tar light oil, or crude benzole, is similar in chemical composition to the crude benzole recovered from the carbonization gases at gas works and in coke-oven plants. The main components are benzene, toluene, and xylene(s) with minor quantities of aromatic hydrocarbons, paraffins, naphthenes (cyclic aliphatic compounds), and phenols, as well as sulfur and nitrogen compounds. [Pg.720]

The conversion of biomass produces carbon, gases, and vapors in the first stage, and then these products are transformed into other compounds, which depend on the operating conditions. Some authors argue that intermediaries, called complex active, are unstable and rapidly converted into vapors and gases. The lifetime of these intermediate materials is less than 10 ms. Vapors intermediates are converted into gases at elevated temperatures and, if rapidly quenched, form complex liquid (bio-oil). For that, the contact time between the components must be less than 1 s. [Pg.595]
