Importance of biofuels Define upgrading
Removal of heteroatoms Improve fuel properties
Existing problems/bottlenecks Many throughout biofuel process Cost looking at upgrading process details
shorter time, different catalyst, etc.

Main objective Examine aspects of upgrading the biocrude
Specific objectives Changing the length of time spent in reactor
Effects on product Mixed catalyst
Possibly improve refinement
Research Objectives
