Summary: A detailed process model for co-gasification of biomass and plastics in a fluidized bed reactor was developed using Aspen Plus software. The effects of process parameters such as plastic content and reactor temperature on the composition and properties of syngas were investigated. The results showed that increasing the plastic content led to higher hydrogen concentrations in the syngas, and increasing the gasification temperature resulted in increased hydrogen content and higher heating value of the syngas.

Summary: This study evaluated the use of hydrothermal liquefaction as a sustainable method to convert municipal sewage sludge into renewable energy source, biocrude. The effects of reaction temperature and residence time on biocrude yield and quality were investigated using response surface methodology. The study found that optimizing the reaction conditions resulted in maximized biocrude yield and energy recovery. The composition and quality of the biocrude were influenced by the reaction temperature. Upgrading and recovering trace metals from the biocrude were also found to be necessary. These findings contribute to the advancement of biorefinery technology and can guide the design of full-scale sludge treatment systems.

Summary: This study comprehensively assessed the properties, environmental influences, and possible utilizations of hydrochar generated from mixed sludge. With the increase of HTL reaction temperatures and residence time, the dry-weight contents of ash and fuel ratio increased while the drybasis contents of volatile matter, carbon, and higher heating value sharply decreased. Hydrochar performed more stable combustion than sludge, but its high ash contents and alkali index implied high risks of slagging and fouling. Hydrochar has a good potential for carbon sequestration and metals and nutrient recovery.

Summary: In this study, nano-structured biochars were produced from microcrystalline cellulose using calcium as a non-conventional catalyst. The impregnation with 2 wt.% of calcium led to the conversion of the initial structure into a well-organized and less defective graphene-like one. The increase of the calcium concentration did not significantly improve the crystallite sizes of the graphene-like materials but rather drastically improved their rate.

Summary: An original bimetallic catalytic system based on Rh(I) and Co(0) in glycerol was developed for the efficient synthesis of biomass-derived amines through a tandem hydroaminomethylation reaction. The multicatalytic system demonstrated high chemoselectivity and good-to-excellent regioselectivity towards linear amines. Cobalt played a major role in reductive amination while rhodium was primarily responsible for hydroformylation.

Summary: The structural properties of carbonized cellulose were investigated using X-ray diffraction, Raman spectroscopy, and transmission electron microscopy. The results showed the formation of graphene stacks with different size distributions during cellulose carbonization. The different characterization techniques gave different significances in determining the crystallite sizes. The study demonstrated that the observed phenomena in cellulose-derived carbon samples could be explained by the combination of these three techniques.
