Desulfurization of transportation Fuels targeting at removal of thiophene/benzothiophene
Fuel Processing Technology, 2008Co-Authors: Wei Dai, Yaping Zhou, Shengqiang Wang, Yan SunAbstract:A new method is presented for deep desulfurization of transportation Fuels targeting at the removal of thiophenic compounds. The method is based on a characteristic condensation reaction of thiophenic compounds with formaldehyde, and the reaction was designed to occur in the pore spaces of activated carbon under catalysis of sulfuric acid. The reaction is selective because the hydrocarbon components of Fuels do not react with formaldehyde at the same condition. Therefore, the quality of Fuel, e.g. the octane number, will not change, and the desulfurization function will not be interfered either by olefin/aromatic components or the dissolved water of Fuels. Because the reaction is occurring in the pore spaces, the desulfurization function is locally intensified and the reaction products were there adsorbed. All those merits were shown firstly by different types of model Fuels, and then by a commercial diesel Fuel. In conjunction with an oxidation treatment, the total sulfur content of the commercial Fuel dropped from 1697 ppm to 14 ppm, which meets the present Fuel Specification of the US.

Characterisation of combustion behaviour of refuse derived Fuel
Journal of The Energy Institute, 2008Co-Authors: Thomas Kolb, S. Bleckwehl, Hans-joachim Gehrmann, Helmut SeifertAbstract:AbstractThe combustion process of heterogeneous solid Fuels like refuse derived Fuel is investigated in a fixed bed reactor. Characteristic parameters are derived for the quantitative description of solid Fuel combustion. The experimental setup of the fixed bed reactor KLEAA at Forschungszentrum Karlsruhe with a volume of ∼10 L, allows for using technical solid Fuel fractions with a maximum particle size of ∼80 mm. It is equipped with gas species sampling train, local temperature measurement and mass control. Characteristic parameters, such as reaction front velocity (RFV), Fuel ignition rate (FIR), Fuel consumption rate (FCR) are derived from experimental data to quantify the combustion behaviour of different Fuels as a function of Fuel Specification and operational conditions. The influence of Fuel moisture content and primary air flowrate on the combustion rate of wood based Fuels is investigated in detail. The RFV of different waste and biomass based solid Fuels is compared. Based on the characteristi...
