  2. 2. Aim  Gasification plays an important role in providing the power, chemical and refining industries with economically competitive and environmentally conscious technology options to produce electricity, fuels and chemicals.  The gasification process for Sırnak asphaltite  The production of liquid and gaseous fuels may improve local industry in energy aspect 2
  3. 3. Scope  The gasification process for Sırnak asphaltite ,  uses a kiln type furnace,  as the heat carrier solid coal ash and flue gas are used.  The process can accept shale fines.  The oil yield varies, averaging approximately 2228% on raw coal basis.  The oil contains 15–20 % low-boiling fractions. 3
  4. 4. Review  The significant amount of electricity is produced primarily from coal in the world as given in Table 1 South Africa 93% Australia 78% Israel 58% Greece 54% Poland 87% Kazakhstan 75% Czech Rep 51% USA 45% PR China 79% India 68% Morocco 51% Germany 41% 4

  19. 19. •The country needs the cleanest fuel to be produced providing the essential oils and gases. For this reason, Kütahya Gediz, Soma lignite, Sırnak asphaltite and lignite locally successfully tested. Advanced coal washing of Şırnak asphaltites, pyrolysis and gasification of clean products could be managed at the projected way. The production of liquid and gaseous fuels may improve local industry in energy aspect and the proposed development in the Southeastern Anatolian region may further improve the diversification of fuels in local energy market. •Pyrolysis of different types of Turkish lignites was succesfully processed in terms of deashing and desulfurization and even reduction of volatile matter. •The specimens of different types of Turkish lignite, Şırnak asphaltite and lignite were greatly desulfurized at 46% and 67% rate by lime, respectively. Soma Kısrakdere lignite was desulfurized at 66% rate by lime. 19
  20. 20. •For Şırnak asphaltite and lignite the heavy media devices should be used for washing and lower ash contents than 15% for clean coal products should be subjected to presented gasification process. •While scale up plant projected, proposed pyrolysis gasification process in order to high amount of oil yield and the highest level of efficiency in the gasification of carbonized gas was managed over 700oC and below 800 oC. Between these temperatures, high liquid and gas fuel production efficiencies were determined at the 55% and 57% values for Şırnak lignite and asphaltite, and other one optimized pyrolysis parameter was the particle size distribution fed to the furnace was ranged among 0,2 mm and 10 microns for Turkish lignites. •Even the projects contributing to the side of the forest waste biomass as raw material, cellulosic waste resource can be processed with the lignites [25-28]. Some extent mixing was carried out in order to improve the pyrolysis quality of Şırnak asphaltite and lignite so that ash and sulfur contents of lignite samples would be so lower than the best gasification conditions. 20
