Pirólisis de residuos de cáscara de Cebada con poliestireno residual para la generación de combustible líquido

Abstract

The aim of the research was to obtain fuel through a pyrolysis process using barley husk and residual polystyrene as raw material, which were obtained from solid plastic waste that was crushed and washed in the laboratory. The barley husk was collected from different mill warehouses where grain peeling processes are carried out, these places are located around San Alfonso market in Riobamba. This chemical recycling was carried out at 400 degrees Celsius in order to analyze the effect of the temperature in the obtention of the final product. The experiment was carried out in a pyrolysis reactor and for the liquid fraction analysis, FT- IR spectroscopy, density, viscosity, flash point, fragmented distillation, GC-MS chromatography and calorific value techniques were applied. The pyrolysis analysis resulted in a high calorific value of 44546.81 kJ/kg. The highest liquid performance was 67.133 percent obtained at 400 degrees Celsius, in this way it was possible to determine that the optimum pyrolysis temperature is at 400 degrees Celsius with a performance greater than 60 percent. In addition, at 400 degrees Celsius, a greater amount, 49.019 percent approximately, of light hydrocarbons ranging from carbon 4 to carbon 12 was verified. It is recommended to carry out studies focused on other process variables to analyze a possible improvement in the performance of the final product.
