| Summary: | The
presence and amounts of chemicals in bio-oil produced by catalytic fast
pyrolysis are affected by the process parameters, hence, the relationships
between the chemicals and process parameters need to be investigated in detail
by multivariate analysis techniques. The present work classifies the most
available 11 chemicals in bio-oil based on the 24 samples (treatments) of
catalytic fast pyrolysis experiments of municipal solid wastes by using
principle components analysis (PCA) and hierarchical cluster analysis (HCA).
There were 3 principle components (PCs), but the first 2 PCs explained 74% of
the total variance. The samples and variables (chemicals) were
clustered into 4 and 2 different groups, respectively, in PCA. The samples and
variables were clustered in 2 main groups and a few subgroups in HCA. Both PCA
and HCA results showed that there was a clear grouping in the samples and
variables. |
