High surface area molybdenum nitride (up to 108 m{sup 2}/g) was synthesized, characterized, and tested for thiophene desulfurization activity. The surface area was found to depend on synthesis temperature profile, mass transfer, and passivation procedure. Passivated and sulfided catalysts retained the bulk structure of face-centered-cubic Mo{sub 2}N. X-ray diffraction and Raman spectroscopy showed no evidence for MoO{sub 3} or MoS{sub 2} formation in fresh catalysts or catalysts sulfided at 673 K. Thiophene desulfurization activity was measured over a broad range Mo{sub 2}N surface areas and reactor condition. Small amounts of tetrahydrothiophene were formed during desulfurization and low-conversion data at 673 K indicate that butane is one of the initial products of the thiophene desulfurization reaction, in addition to butadiene and the butenes.
