Kinetics of carbon dioxide, methane and hydrolysis in co-digestion of food and vegetable wastes

D. Pham Van; M.G. Hoang; S.T. Pham Phu; T. Fujiwara

Volume 4, Issue 4 , October 2018, , Pages 401-412

https://doi.org/10.22034/gjesm.2018.04.002

Abstract
  Kinetic models which can express the behaviors of hydrolysis and biogas generation more precisely than the conventional models were developed. The developed models were evaluated based on the experimental data of six batch reactors. Anaerobic digestion test was co-digestion of food and vegetable waste ...  Read More

A new kinetic model for biogas production from co-digestion by batch mode

D. Pham Van; M.G. Hoang; S.T. Pham Phu; T. Fujiwara

Volume 4, Issue 3 , July 2018, , Pages 251-262

https://doi.org/10.22034/GJESM.2018.03.001

Abstract
  Coming out from the growth kinetics, the Gompertz model has been developed and considered as the best one for simulating the biogas production from anaerobic digestion. However, the model has failed to describe the starting point of the process, and no-sense of lag phase constant has been pointed out. ...  Read More
