Short description of Phase 1
Phase 1 of the BIOPOROMAT
project consisted in 5 research activities. All of them were realized in
time, which led to the achievement of the 2022 project objectives and
overcoming the project results deliverables. A brief description of
these activities is presented in the following paragraphs.
Act. A1.1 refers to the evaluation of the availability and types of
biomass wastes and to chemical, morphological and structural
characterization of some lignocellulosic biomass in order to have a
realistic assessment on the valorization potential as well as on the
pre-treatments of the feedstocks subjected to thermochemical conversion
processes.
Considering the findings generated in this stage, the activity had as
result the design of biomass wastes processing flow (feedstock,
pre-treatments, conversion path) that will be integrated in a
multi-stage protocol in order to obtain an innovative material with
tailored properties which feature an organic core (CMNS) and a polymeric
outer layer.
Act 1.2 presents 2 synthesis methods to prepare carbonaceous materials
micro and nano structured through slow pyrolysis and hydrothermal
conversion.
The experimental devices and facilities were adapted and work protocols
were developed. Two laboratory-scale reactors, equipped with a heating
system and temperature and pressure control were used in order to obtain
CMNSs. In the same context, preliminary tests were carried out in an
experimental configuration that allows thermal processing using a system
equipped with a CO2 laser and a displacement in x, y coordinates (Act
1.3).
As a result of experimental (Act 1.4), relevant data were obtained
regarding the chemical, morphology and structural characterization of
CNMS obtained in previous activities. Several advanced characterization
methods including FT-IR spectroscopy, SEM scanning electron microscopy,
Raman spectroscopy, TGA thermogravimetric analysis and dimensional
analysis were used. Along with the preliminary evaluation of porosity
characteristics (Act 1.5) as well as the estimation of the CNMS
functionalization possibilities, all data generated in the first phase
allow the design of porous materials with tailored properties adapted to
the targeted applications in this project (environmental remediation and
hydrogen storage).
