I. Thermochemical Conversion of Biomass and Nanocatalyst Synthesis 

      by Prof. Fang Zhen

This presentation includes 5 parts:

1. Introduction of Myself

(education and research experience);

2. Thermal Conversion of Biomass

(thermal gasification, fast-pyrolysis, hydrothermal hydrolysis, gasification and liquefaction, hydrothermal de-polymerization of biomass and synthesis of chemicals);

3. Hydrothermal Oxidation and Reaction of Organics

(Supercritical water oxidation, hydrothermal flame, recycling of polymers, extraction chemicals from biomass and fuel upgrading);

4. Hydrothermal Synthesis of Nanoparticles

as catalysts and sensors for biomass conversion

[synthesized particles for catalytic H₂ production (e.g., Ni, Ni-Sn), for liquefaction (Pt/SiO₂-Al₂O₃), for catalytic hydrothermal oxidation (e.g., MnO₂, TiO₂, ZrO₂) and for Fischer-Tropsch process (Fe/Co), for sensors (e.g., SnO₂, Fe₂O₃, TiO₂, ZrO₂, CeO₂) and biomaterials (phosphates of Ca, Mg, Co and Fe)];

5. Promising Areas

(1) Production of HC liquid fuels

a. Fischer-Tropsch: diesel from syngas (High-P)

b. Upgrading bio-oils (vegetable oil, fast-pyrolysis oil, liquefied oil);

c Gasoline production from glucose

(2) Production H₂ from biomass and water

a.       Hydrothermal gasification (methanol synthesis from hydrothermal gas: H₂+CO₂)

b. H₂ from photo-decomposition of water with catalyst (e.g., TiO₂)

(3) Hydrothermal hydrolysis or pretreatment of biomass for biological conversion;

(4) Fast pyrolysis for biopolymers, chemicals and fuels;

(5) organics synthesis/extraction in hydrothermal water;

(6) Catalyst synthesis in hydrothermal water.
