Perspectivas en el estudio de la autoignición de combustibles renovables gaseosos en temperaturas moderadas y bajas: una revisión

The increased energy demand and restrictions regarding pollutant emissions have sparked the search for different renewable energy sources, as well as for the improvement of thermal processes, with a focus on reducing the consumption of fossil fuels. Renewable gaseous fuels seem to be a promising alternative for solving this issue, along with the different high-efficiency, low-emissions technologies that operate at low and moderate temperatures (600-1000 K). However, the implementation of these approaches is limited by the autoignition phenomenon and the different difficulties in predicting its occurrence in the aforementioned operation range. To identify the reasons for this fact, we carried out a review of the different research works conducted in the field. It was evidenced that most studies focus on performing adjustment processes that require prior experimentation. This allowed identifying the need to conduct a research work focused on the autoignition phenomenon in the low and moderate temperature range while using renewable gaseous fuels, as well as on improving the predictive models for calculating ignition delay times.
