Syngas formation by selective catalytic oxidation of liquid hydrocarbons in a short contact time adiabatic reactor

Syngas formation from gasoline in adiabatic reactor: Thermodynamic approach and experimental observations

“…The higher O 2 /C molar ratio may cause deactivation of the catalyst due to the high tem- perature in the frontal part of the monolith, as it was observed in Ref. [15]. Compared to gasoline, moderate heat evolved and smaller increase in the temperature, about 40 • , is observed for isooctane in the same range of the O 2 /C ratio.…”

“…The inlet section of the monolith (about 15 mm) was additionally promoted by Ru + La. Both LaNiPt (1 wt.%) and LaRu (1 wt.%) active compounds were supported via wet impregnation followed by drying and calcinations in air at 900 • C [15,18]. Unloaded monoliths, the 10 mm long fragments of an extruded corundum monolith with a rectangular cross-section (1.9 mm hydraulic diameter) of its channels, were placed in front of and behind the two metallic catalysts to reduce radiation heat loss.…”

“…Both the product gas composition and temperature at the outlet of the catalytic monoliths were in good agreement with the thermodynamically predicted data. Simulations of syngas formation have been previously performed using isooctane, as a standard reference fuel for gasoline [15]. However, reactivity of different gasoline components was found to affect considerably both the operational parameters and product composition in the reforming process.…”

“…In our previous papers [15,16], the particulars of syngas formation from liquid hydrocarbons such as isooctane and gasoline over LaNiPt/LaRu catalyst washcoated on microchannel ceramics and metallic monoliths were highlighted. Also discussed were few problems encountered with a short contact time reactor operating at a pilot scale, issues that are largely independent of the catalysts employed.…”

“…They have further proposed that new process designs for fuel processing can take advantage of the successful experience of environmental catalysis in automotive and stationary applications using monolithic catalysts and other substrates such as heat exchangers. Bobrova et al, 2005 have studied syngas formation by selective catalytic oxidation of liquid hydrocarbons in a short contact time adiabatic reactor. Their research involved pilot plant scale exploration of syngas formation from liquid fuels like isooctane and gasoline by selective catalytic oxidation at short contact times at nearly adiabatic reactor conditions.…”
