Summary

Results from the operation of methanogenic reactors of three different sizes, using coffee pulp juice as raw material, are presented. All reactors were packed with unreticulated polyurethane foam and geometrical similarity was maintained. Pilot plant operation showed lower gas production per unit reactor volume but higher conversions per unit of organic load, even at lower temperatures.

Résumé

Les résultats présentés concernant le fonctionnement de trois réacteurs méthanogènes de dimensions différentes, utilisant comme matière première le jus de pulpe de café. Tous les réacteurs étaient compactés avec de la mousse de polyuréthane non réticulée, et avaient des formes géométriques similaires. Les opérations à l'échelle pilote ont donné une moindre production de gaz par unité de volume, mais un taux de conversion par unité de charge organique plus élevé, même à des températures inférieures.

Resumen

Se presentan los resultados de la operación de tres reactores metano-génicos de differente tamaño, usando jugo de pulpa de café como materia prima. Los reactores fueron empacados con esponja de poliuretano no reticulado y se mantuvo una similitud geométrica. La operación de una planta piloto mostró una menor producción de gas por unidad volumétrica de reactor pero conversiones mejores, aún a más bajas temperaturas.
