Abstract
Biomass is considered to be one of the highest potential renewable energy sources to meet the requirements of energy in the world, where it can be used as an effective alternative for renewable energy sources, including electricity and heating, as well as fuel used in transport. One of the most common problems accompanying the usage of biomass through gasification processes to produce gases is the amounts of undesirable formed Tars. In this paper, a Laser Induced Fluorescence spectroscopy (LIF) method was incorporated to identify the produced Tar compounds at high temperature in the gasification technology. The effect of tars deposition when gases are cooled was greatly reduced by introducing a new concept of the measurement cell. The processed mixtures of Tar samples were prepared with the standard constrictions of measured aromatic and Polycyclic Aromatic Hydrocarbons (PAHs) by using Gas Chromatograph (GC). Optical Parametric Oscillator (OPO) laser with a tuning range of (200 to 2400) nm and peak energy of 2.2 mJ was used to excite the Tar compounds, which have fluorescence properties in the range of ultraviolet|blue spectrum. The investigated measurements were evaluated by incorporating the Excitation-Emission Matrices (EEM), which was presented as a time-consuming method of online Tar monitoring.
