"Alumina supported Rh-LaCoO3 has been investigated for the catalytic conversion of tar produced by biomass pyrolysis into hydrogen-rich gas."

"The best performing catalysts have consisted of nickel and magnesium supported on fluidizable alumina. "

Now, the questions are:
Would alleviated temperatures, in theory, improve the effectiveness of these catalysts?
Why are the catalysts "alumina-supported"?
What is the purpose of having "fluidizable" alumina?
All constructive replies are welcomed. Thanks in advance.
P.S. Excuse my poor English.
