Evaluation of Liquid Hydrocarbons Formation and Energy Consumption in Consecutive Biomass and Carbon Feedstock to Liquid Hydrocarbons Transformation Process
Authors: , , , ,
Abstract: Evaluation of liquid hydrocarbons formation and energy consumption during biomass and carbon containing feedstock was provided. For experiments birch, spruce saw dust, bottom peat, peat moss and brown coal were used. Experiments were provided using semi-laboratory set-up consists of gasification furnace for water gas shift reaction, methanol synthesis reactor and hydrocarbons synthesis reactor. The highest liquid hydrocarbons yield was found to be 0.72 kg(Hydrocarbons)/kg(initial source) for brown coal. The lowest liquid hydrocarbons yield 0.51-0.55 kg(Hydrocarbons)/kg(initial source) was found for wood residuals. Deferent types of peat characterizes by medium liquid hydrocarbons yield 0.62-0.64 kg(Hydrocarbons)/kg(initial source). For all substrates a negative heat balance was obtained. The highest values of energy needed to be inputted in the system were found to be 4.8 MJ/kg for brown coal. The lowest value of energy needed to be inputted in the system was found to be 3.3-3.6 MJ/kg for wood residuals. In all cases liquid hydrocarbons consists of 1-7 wt. % paraffins, 1-2 wt. % olefins and 90-95 wt. % of various aromatic compounds.
