The Pyrolysis Behavior of Victorian Lignite at Elevated Pressures: Contrast to Bituminous Coal

Victorian lignites (brown coals) in Australia have long been the mainstay of the Victorian economy, providing low-cost electricity to the state. In order to secure energy supplies for the future and to reduce the environmental impacts of power generation using the lignites, the Cooperative Research Centre (CRC) for Clean Power from Lignite is developing an Advanced Pressurized Fluidized-Bed Com...

The effects of phosphoric acid and pyrolysis temperature to the formation of flaky graphite from lignite

The flaky graphites were prepared from lignite. The effects of phosphoric acid ratios and pyrolysis temperatures on flake formation were studied by SEM, TEM and XRD. The results showed that the flaky graphite occurred at a pyrolysis temperature of 600°C with a 1.0:1.0 ratio of carbon to phosphoric acid. The flaky formation was almost completed by pyrolysis at 800°C and with a 1:2.0 ratio of car...

compactifications and representations of transformation semigroups

this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...

Study on the NO removal efficiency of the lignite pyrolysis coke catalyst by selective catalytic oxidation method

Selective catalytic oxidation (SCO) method is commonly used in wet denitration technology; NO after the catalytic oxidation can be removed with SO2 together by wet method. Among the SCO denitration catalysts, pyrolysis coke is favored by the advantages of low cost and high catalytic activity. In this paper, SCO method combined with pyrolysis coke catalyst was used to remove NO from flue gas. Th...
