| description | The objective of this research was to increase the yield and quality of the pulp generated from the industrial chips of Pinus pseudostrobus L. It was carried out with the industrial chips of the wood of Pinus pseudostrobus L. of SCRIBE Company in Morelia, Michoacán, México. The temperatures used were 165 °C and 170 °C, cooking times of 40 minutes and 80 minutes and loading of reagents of 18% and 22%. The response variables were: yield, kappa number, rejects and residual alkali according to the TAPPI standards. The results were analyzed using an experimental factorial design. Yield varied from 33% to 52%; kappa number of 11 to 40; The rejections from 3.4% to 25.4% and the residual alkali from 3.1 g/L to 11 g/L. The yield maximization (54.8%) gave a temperature of 162 ° C, cooking time of 40 minutes and loading of reagents of 23%. Minimizing the kappa number variable (11.2) was obtained at a temperature of 166 ° C, cooking time of 26 minutes and loading of reagents of 19%. Minimization of the rejections were presented at a temperature of 162 °C, 26 minutes of cooking and a load of reagents of 19%. Finally, the residual alkali minimization (4.9 g/L) was presented at a temperature of 169.18 °C, cooking time of 60.14 minutes and loading of reagents of 20%. The operating conditions in the cooking process provide a 50% yield relative to the initial chip percentage used and a lower kappa number of 15.8 compared to pulp results from published pine species. |

El objetivo de esta investigación fue incrementar el rendimiento y la calidad de la pulpa generada a partir de astilla industrial de Pinus pseudostrobus L. Se trabajó con la astilla industrial de la madera de Pinus pseudostrobus L. de la empresa SCRIBE planta Morelia, Michoacán, México. Las temperaturas empleadas fueron 165 °C y 170 °C, los tiempos de cocción 40 minutos y 80 minutos, cargas de reactivos de 18% y 22%. Las variables de respuesta fueron: rendimiento, número de kappa, rechazos y álcali residual de acuerdo con las normas TAPPI. Los resultados se analizaron aplicando un diseño experimental factorial. El rendimiento varió de 33% a 52%; el número de kappa de 11 a 40; los rechazos de 3.4% a 25.4% y el álcali residual de 3.1 g/L a 11 g/L. La maximización del rendimiento (54.8%) se obtuvo a una temperatura de 162 °C, tiempo de cocción de 40 minutos y carga de reactivos de 23%. La minimización de la variable número de kappa (11.2), se obtuvo a una temperatura de 166 °C, tiempo de cocción de 26 minutos y carga de reactivos de 19%. La minimización de los rechazos se presentó a una temperatura de 162 °C, 26 minutos de cocción y carga de reactivos de 19%. Por último, la minimización del álcali residual (4.9 g/L) se presentó a una temperatura de 169.18 °C, tiempo de cocción de 60.14 minutos y carga de reactivos de 20%. Las condiciones de operación en el proceso de cocción proporcionan un rendimiento de 50% con respecto al porcentaje de astilla inicial utilizada y un número de kappa de 15.8 menor en comparación con resultados de pulpas de especies de pino publicados.
