Synthesis of two new Nickel and CopperNickel vanadates used for propane oxidative dehydrogenation

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2013
Two new vanadates have been successfully synthesized by the hydrothermal and coprecipitation methods. Both vanadates were calcined at 600 °C and the resulting catalysts were tested on reaction of oxidative dehydrogenation of propane.

Experimental and analytical study of nitric oxide formation during combustion of propane in a jet-stirred combustor [PDF]

open access: yes
A jet-stirred combustor, constructed of castable zirconia and with an Inconel injector, was used to study nitric oxide formation in propane-air combustion with residence times in the range from 3.2 to 3.3 msec and equivalence ratios varying from 0.7 to 1.
