< Synthesis gas (H2/CO) related chemistry is studied with this
30 cm long tubular reactor. This system features the following
main system components:
Three gas mass flow controllers for hydrogen, carbon
monoxide and carbon dioxide. Each MFC is equipped with an
automated air piloted valve to ensure a positive shutoff of the
reactant gas flow.
The 2.5 cm ID reactor and its associated single zone heater.
The reactor is rated for use up to 100 bar @ 550 ˚C and is
equipped with an internal pre-heater and catalyst spools for
easily changing the catalyst loading.
A jacketed gas/liquid product separator coupled with an
automated back pressure regulating system. The jacket is
used for cooling the reaction products.
The process controller and valve interface are conveniently
located on the lower shelf of the moveable reactor stand.
The system was provided with a high pressure liquid meter-
ing pump (not shown) to optionally introduce liquid reactants
into the reactor.
This system is used primarily to facilitate the study and
development of industrial scale catalysts from biomass ash
and char, focusing on engineered manipulation of the char
structure and surface to enhance catalytic activity and selec-
tivity. The emphasis is on catalysts for the synthesis of liquid
fuels and chemicals such as the conversion of synthesis gas
to mixed alcohols.
