PROCESSES BASED ON INTRINSIC SENSORS TO FIBER OPTICS TO EVALUATE THE QUALITY OF BIODIESEL AND DIESEL OIL

摘要

processes based on sensors intrinsic to fiber optics to assess the quality of biodiesel and diesel oil refer to three processes (temperature-assisted process, partial immersion process and standard dilution process) based on the response of intrinsic sensors to the optical fiber that combined or used individually, it is possible to evaluate the quality of biodiesel and diesel oil and make it possible to quantify the content of these fuels in homogeneous mixtures, without the need for segregation of components and without requiring the use of special optical fibers. the temperature-assisted process consists of verifying the response of a fiber sensor when in contact with liquid fuel samples whose temperatures are purposely modified to be different from the ambient temperature. the partial immersion process consists of verifying the response of a fiber sensor, specially modified to act in the interferometric configuration, partially immersed in liquid fuel samples whose temperatures are preferably equal to or close to the ambient temperature. the standard dilution process consists of checking the response of a fiber sensor when in contact with liquid fuel samples whose temperatures are preferably equal to or close to room temperature, but previously diluted in standard substance
