Joint thermochemical process and reforming applied to residual biomass and zero-waste approach

Funded by:  ERDF -  Emilia-Romagna 2014-2020
Start: April 2016
End: May 2018

The project is aimed at developing 2 innovative processes and related prototypes to treat pruning, wine marc, tomato peels and agro-energy residues such as digestate, garden residues and the organic fraction of urban wastes.

The first process (1) includes a pyro-gassifier updraft (75 kW) combined with catalytic tar cracking and reforming process. This system is intended to feed an internal combustion engine used to produce combined heat and power (CHP). The R&D activity is targeting syngas quality and quantity and ultimately to improve the CHP efficiency and related environmental impact.

The second process (2) includes as well a thermochemical process combined with reforming to obtain an hydrogen enriched gas, biochar end by vapor condensation and quenching a high calorific oil. The prototype will have a capacity of 2 kg/hr.

Process byproducts will undergo further studies and experimental processes. A dedicated study and activities will prove that biochar has to meet human and toxicity safety standards and will fit soil amendment requirements. Produced syngas and light hydrocarbons will be treated to produce a biological synthetic gas (Bio-SNC) and will be proved to be equivalent to bio-methane.

My role is addressing the organization and achievements of results for process and prototype (2) and I am involved in the sustainability assessment of the considered processes.
