Energy production from biomass. (Part 2): Conversion technologies

Fast pyrolysis for production of liquids has developed considerably since the first experiments in the late 1970s. Many reactors and processes have been investigated and developed to the point where fast pyrolysis is now an accepted feasible and viable route to renewable liquid fuels, chemicals and derived products. It is also now clear that liquid products offer significant advantages in storage and transport over gas and heat. These advantages have caused greater attention to be paid to fast pyrolysis, leading to significant advances in process development. The technology of fast pyrolysis for liquids is noteworthy for the wide range of reactor configurations that have been developed to meet the stringent requirements for high yields of useful liquids, for use as a fuel in boilers, engines and turbines and as a source of chemical commodities. This review summarizes the key features of fast pyrolysis and the resultant liquid product and describes the major reaction systems and processes that have been developed over the last 20 years.

An overview of fast pyrolysis of biomass

The technical and economic feasibility of biomass gasification for power generation

The main purpose of this review is to update the information on gasification tar, the most cumbersome and problematic parameter in any gasification commercialization effort. The work aims to present to the community the scientific and practical aspects of tar formation and conversion (removal) during gasification as a function of the various technological and technical parameters and variables.

Biomass Gasifier "Tars": Their Nature, Formation, and Conversion

A survey of gasification, pyrolysis and liquefaction technologies for biomass and waste has been conducted to identify processes suitable for opportunities in the UK and Denmark. Combustion of biomass and waste is omitted as it is considered to be well established technology with a wide variety of systems available for implementation. Of 57 processes identified as being relevant that are currently or recently under development, 22 have been selected for more detailed investigation. (author)
