Bio-oil production can be performed at an appropriate scale, stored and finally shipped together with bio-oil products from other bio-oil plants to a central site for gasification conversion to product gas or syngas at any desirable time (Venderbosch and Prins, 2010). Hence bio-oil gasification could be economically put into mass production.
The distributed conversion of biomass to bio-oil or bio-oil/char slurry via fast pyrolysis as a potential alternative to centralized bio-syngas production via biomass gasification is attracting more and more attention.

High temperatures (above 600掳C) maximize pyrolysis gas yields (about 80% wt). Bio-oil can be used as a substitute for fossil fuels in boilers, turbines and diesel engines to generate heat, power or combined heat and power or as a source of chemicals. Its production is decoupled from power generation, unlike combustion and gasification.

Gasification is a technological process that can convert any carbonaceous (carbon-based) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed material causing a series of chemical reactions to ...

As an example, the specific gravity of bio-oil produced from fast pyrolysis of switchgrass is approximately three times higher than that for the switchgrass pellets (Wright et al., 2008). Bio-oil is easier to handle and transport than the raw biomass, reducing transportation costs to a centralized large-scale gasification
Get PriceThe main products of pyrolysis are gases, bio-oil and char. The reason for adopting pyrolysis, instead of gasification, combustion or incineration, is the production of bio-oil as well as synthesis gas and char as by-products. Another reason is the higher energy recovery efficiency as compared to other thermochemical reactions.
