    Co-liquefaction Behaviour of Elbistan Lignite and Olive Bagasse
    (Iop Publishing Ltd, 2016) Karta, Mesut; Depci, Tolga; Karaca, Huseyin; Onal, Mehmet; Coskun, M. Ali
    In the present study, co-liquefaction potential of Elbistan lignite and Balikesir olive bagasse were investigated by direct coal liquefaction process. The olive bagasse is a cheap and abundant biomass, so it is used to decrease the cost of oil production from the lignite. The effect of blending ratio of the lignite and the olive bagasse on liquefaction conversion and oil yield were investigated. Characterization studies of the starting materials were done using XRD, FTIR, DTA/TG and elemental analysis. Elemental compositions of liquefaction products were also determined and the composition of the obtained oil was identified by GC/MS. DTA and TGA results indicated the synergistic effect of the lignite and the olive bagasse and maximum oil conversion (36 %) was obtained from 1: 3 blending ratio of lignite: olive bagasse. The results showed that the obtained oil was paraffinic-low waxy oil with 22.5 MJ/kg of calorific value and 0.95 g/cm(3) density.

    Liquefaction Potential of Adiyaman Peat
    (Iop Publishing Ltd, 2016) Karaca, Huseyin; Depci, Tolga; Karta, Mesut; Coskun, M. Ali
    In the present study, liquefaction potential of Adiyaman peat was studied by direct liquefaction technique to obtain oil as a fuel purposes due to its high carbon and hydrogen content and low sulphur ratio. The peat and liquefaction products, named char, asphaltene, preasphaltene and oil, were characterized by XRD, FTIR, SEM, DTA/TG and elemental analysis. The compositions of the obtained oil were also identified by GC/MS. The results indicated that the obtained oil was paraffinic-low waxy oil with 21.73 MJ/kg of calorific value and 0.93 g/cm(3) density and it was composed of naphthalene and phenolic groups. The oil conversion ratio was found to be 29 %.
