7.2. Approaches to Obtain High-Quality Bio-Oil
Improving the quality of bio-oil using heterogeneous catalysis should be given high priority to allow the production of improved bio-oil for use within modern refinery streams.The overriding aim should be that pure bio-oils could be coprocessed with hydrocarbon fractions, such as vacuum gas
oils, in a conventional refinery, giving the bio-oil the role of feedstocks or cofeedstocks in petroleum streams
