Corn cob biomass residues: Synergies between thermochemical processes for biofuel production and adsorbent materials for the bioenergy sector

This research uses corn cob (CC), a renewable material, to make biofuels. The energy conversion was done by conventional and flash pyrolysis (750–850 °C), showing how the process affects the yield and properties of the biofuels. The CC stood out for their high carbon content (48.19 %) and low ash co...

The energy conversion was done by conventional and flash pyrolysis (750–850 °C), showing how the process affects the yield and properties of the biofuels. The CC stood out for their high carbon content (48.19 %) and low ash content (1.16 %). Flash pyrolysis increased the gaseous fraction (69.8 %) and the concentration of combustible gases (higher heating value (HHV) = 16.31 MJ/kg). Research has also been carried out on the production of activated carbons from CC char to separate gas mixtures, store gas or upgrade biogas. Higher temperatures and/or amounts of activator improved their textural properties (BET surface area and total pore volume up to 1982 m<sup>2</sup>/g and 0.820 cm<sup>3</sup>/g). These adsorbents are highly effective in CO<inf>2</inf> adsorption, with a capacity of up to 15.3 mmol/g at 3 MPa for that obtained with KOH at 700 °C and 2:1 wt ratio. They are good at absorbing methane at 3 MPa with a maximum of 8.8 mmol/g when prepared with KOH at 800 °C and 2:1 wt ratio. Hydrogen adsorption was limited. The potential of CC for biofuel production through pyrolysis and the development of adsorbents applicable to the bioenergy sector have been proven.Eleonora Ciurcina thanks the Spanish National Research Council (CSIC) for the 2021 JAE INTRO ICU SCHOLARSHIP [Ref: JAEICU21-INCAR-9], Recovery and Resilience Mechanism.
