Utilizing biomass as a renewable source of carbon is one of the most exciting challenges of current research in chemical engineering. This has a special value in connection with the increasing concern on global warming, urging a reduction of the utilization of fossil resources in order to lower CO2 emissions.
Liquefaction processes are among the most important approaches for the production of transportation fuels and, possibly, renewable chemicals from biomass. They all involve processing biomass at high temperature, with the production of a liquid product (called bio-oil or biocrude) rich in organics, with a much higher energy density than the original biomass. This oil can in turn be upgraded to transportation fuels or be the starting point for the production of chemicals and materials. Pyrolysis has been one of the most investigated approaches for the production of liquid fuels from biomass, although the properties of the resulting bio-oils are usually far from those of transportation fuels. More recently, interesting perspectives have been offered by catalytic pyrolysis, where the adoption of proper catalysts results in much better properties of bio-oils, e.g., lower oxygen content and better boiling point distribution. Biomass liquefaction can also be successfully achieved through hydrothermal liquefaction (HTL), where the unique reaction environment with hot compress water and the addition of homogeneous or heterogeneous catalysts can result in high yields of high-quality biocrudes, even from low-value biomass feedstocks and organic waste.
This Special Issue aims at gathering recent, high-quality research contributions in the field of catalytic liquefaction processes for biomass, for the production of sustainable biofuels and/or chemicals. Possible topics include (but are not limited to):
- Experimental studies on catalytic pyrolysis or catalytic hydrothermal liquefaction;
- Comparison between catalytic and noncatalytic biomass liquefaction processes;
- Upgrading of bio-oils from catalytic liquefaction processes to final fuels and chemicals;
- Blending and co-refining of bio-oils from catalytic liquefaction processes for drop-in fuels;
- Development of novel catalysts for thermochemical liquefaction;
- Case studies on pilot or demonstration scale plants;
- Modeling studies and technoeconomic evaluations.
I hope that you may find this Special Issue of interest for your research and look forward to receiving your contributions.
