Activation Of Biochar From Olive Residues: A Predictive Model For Yield And Surface Area, Franco Berruti, Anastasia Colomba, Cedric Briens

Bio-Char II: Production, Characterization and Applications

A great amount of work in the literature is dedicated to the kinetic modelling of gasification reactions, while a limited number of authors have paid attention to the evolution of physical parameters, which are very important in the case in which the reaction is applied to the production of activated carbons. The Volume reaction model (VRM) [1], the Shrinking core model (SCM) [2], and the Random pore model (RPM) [3] are unable to provide a relationship between kinetics and the physical properties of the activated carbon and, particularly, between yield and surface area.

Challenges And Progresses Made On The Microkinetic Description Of Lignin Liquefaction: Application Of Group Contribution Methods, Manuel Garcia-Perez, Evan Terrell, Linda Broadbelt

Pyroliq 2019: Pyrolysis and Liquefaction of Biomass and Wastes

In this presentation a comprehensive microkinetic modelling framework and experimental tools are used to describe product yield and composition of direct lignin liquefaction processes with and without solvents (See Figure 1). With the framework proposed we aim to develop a unified theory and models capable of describing both dry (pyrolysis) and wet (hydrothermal and solvolysis) lignin liquefaction processes. An important phenomenon that has been shown to occur during lignin pyrolysis (as well as cellulose) is the formation of a liquid intermediate phase, and subsequent ejection of heavy products (>~250 Da) as aerosols from this intermediate. In our presentation we …
