Preliminary
tests for external and internal mass transfer resistance were
performed at 300 ◦C with varying stirring speeds (500–700 rpm)
and size ranges of catalyst particle (0.2–0.6 mm). It was confirmed
that HDO reaction was conducted in kinetic controlled regime in
this work by applying a vigorous stirring (700 rpm) and small catalyst
particles (0.20–0.25 mm).
