Fast microwave-assisted thermochemical conversion of biomass for biofuel production
… renewable energy sources. In this respect, biomass provides a carbon-neutral and sustainable solution. Pyrolysis and gasification belong to thermochemical processes which are currently the most appropriate and widely used among all the biomass utilization technologies. Microwave irradiation …

Multi-scale chemistry modeling of the thermochemical conversion of biomass in a fluidized bed gasifier
The thermochemical conversion of biomass to fuels via syn-gas offers a promising approach to producing fungible substitutes for petroleum derived fuels and chemicals. In order for these fuels to be adopted, they must be produced in a cost-competitive way. Unfortunately, there exist a number of …

Hydrothermal Process for Bioenergy Production From Corn Fiber and Swine Manure
… increasing concerns about the net energy balance of corn ethanol, food prices, and efficiency of the corn milling process, other types of liquid fuels such hydrocarbons from thermochemical conversion of biomass have become potentially promising. This study aims at investigating the oil-formation …
