Avello Bioenergy: Biomass Fast Pyrolysis

Avello Bioenergy is Iowa State, United States based non-transportation petroleum replacement products producer company. Its proprietary process Avello ®FRAC is based on the fast pyrolysis of biomass and bio-oil fractionation.

Feedstock

Avello ®FRAC is a feedstock flexible process. Agricultural residues, forestry and mill residues, woody biomass including poplar, eucalyptus, willow and dedicated energy crops such as switchgrass, miscanthus, giant cane and reed canary grass are suitable for it.

Avello ™FRAC biomass fast pyrolysis technology

Avello ™FRAC attempts fast pyrolysis of the biomass which means heat induced rapid thermal decomposition of carbonaceous organic matter in an oxygen free environment. The process includes a system to prepare feedstock by drying and grinding, a reactor to process biomass in optimal conditions of around 500°C reaction temperatures and high heating rates, removal of the biochar, a system to collect oil and product storage system. The system produces bio-oil along with biochar and non-condensable gases. This is followed by the fractionation of the bio-oil by using tradmark separation technology.The fractions can be used for various applications.

Products

Bioasphalt® binder is a registered tradmark product of Avello Bioenergy. It can directly replace petroleum based liquid asphalt or may be used as an additive after blending.

Biofuel Oil™ is Avello Bioenergy’s tradmark renewable liquid fuel for heat and power applications. Heavy and light versions of Biofuel Oil are under development for use as petroleum replacements and blending stocks for existing applications.

Biochar The leftover plant matter after pyrolysis is called biochar. It has applications in renewable heat and power generation or as soil amendment and carbon sequestration agent. The company plans to market Biochar as a soil amendment and a potential carbon sequestration agent. Its combustion in furnaces and boilers and co-firing with coal in power plants enhances its fuel uses for heat and power.

Plant

Avello has a pilot unit running a ¼ TPD of biomass per day at present while the company is in the process of raising the capital for its 2.5 TPD demonstration plant that will produce petroleum replacement products for precommercial testing.
