Abstract	Researchers studied steam reforming (SR) and autothermal reforming (ATR) of n-butanol over 0.5 wt% Rh/ZrO2 catalyst at 500, 600 and 700 °C, atmospheric pressure, steam to carbon (S/C) molar ratio of 4 and oxygen to carbon (O2/C) molar ratio of 0.1. They also examined the influence of the O2/C ratio on performance at 500 °C. They compared catalyst performance, product distribution and short-term stability, with plain ZrO2 support to derive a reaction network, including contributions of reactions in the gas phase, on the support and on Rh.

Abstract
Reports results of a study of fluidized bed steam reforming of butanol at 650 °C, atmospheric pressure and a steam to carbon (S/C) molar ratio of 14.7. Researchers explored the influence of the space velocity (G_C1HSV) with a variety of catalysts.
The use of a Ni/Al catalyst with 28.5 wt.% Ni content gave almost equilibrium conditions at a G_C1HSV of around 11000 h^− 1. At higher G_C1HSV values, carbon conversion to gas and gas yields diverged from equilibrium values. Researchers analyzed the catalyst composition as well, using a number of Ni/Al research catalysts modified with Ca or Mg, studying their effect on the nickel reducibility and activity. sented less carbon content on the catalyst surface.
