Personal Details

Frederico G Fonseca attended Chemical Engineering in Lisbon Tech (IST-ULisbon) and briefly integrated the group in 2015, in a small project entitled “Moisture content as a design and operational parameter for fast pyrolysis”. In February 2018, he started his doctoral project focusing on the modeling of fast pyrolysis based on the materialized bioliq® concept. This work consists of the development of a model in a commercial chemical engineering simulation software (Aspen Plus™), which was chosen due to its academic and industrial ubiquity.
To ensure that the desired rigor and flexibility of the model are ensured, a great focus is put in the representation of biomass, the reaction network that characterizes fast pyrolysis, and the produced bio-oil. Within this context, Mr. Fonseca applied successfully for a KHYS-funded research exchange that focused on the use of Near-Infrared Spectroscopy (NIRS) to develop predictive models to estimate properties (such as moisture, ash content) of wheat straw. This project took place in the NIRS Laboratory (, of the Agricultural Engineering Department of the King Mongkut’s Institute of Technology, Ladkrabang, Bangkok, Thailand.
