Se presenta la composicion para análisis de estabilidad en un reactor supercrítico de agua en escala reducida, mezcla de freones, en una proporcion adecuada de refrigerantes (22.5/77,5 % en fraccion de masa), particularmente pentafluoroetano R-125 y difluorometano R-32. También se presenta un procedimiento para uso de la mezcla que permite su utilizacion en modelos de reactores en escala reducida y la obtencion de parámetros de funcionamiento reales, logrando un comportamiento similar que en el agua en estado supercrítico pero a mucho menor presion 6,23 MPa y a temperaturas de 160-180s C, muy inferiores en comparacion con la presion de 25 MPa y las temperaturas de 280°C- 500°C al usar agua.The composition for stability analysis is presented in a supercritical reactor of water on a reduced scale, mixture of freons, in a suitable proportion of refrigerants (22.5 / 77.5% in mass fraction), particularly pentafluoroethane R-125 and difluoromethane R- 32 A procedure is also presented for the use of the mixture that allows its use in small-scale reactor models and the obtaining of real operating parameters, achieving a similar behavior than in water in a supercritical state but at a much lower pressure 6.23 MPa and at temperatures of 160-180s C, much lower compared to the pressure of 25 MPa and temperatures of 280 ° C- 500 ° C when using water.
