Abstract
Composite catalysts having bismuth silicate(s) (e.g. Bi2SiO5) and transition metal oxide(s) (e.g. nickel oxide) impregnated on mesoporous silica supports such as SBA-15, mesoporous silica foam, and silica sol. Methods of making and characterizing the composite catalysts as well as processes for oxidatively dehydrogenating alkanes (e.g. n-butane) and/or alkenes (e.g. 1-butene, 2-butene) to corresponding dienes (e.g. butadiene) employing the composite catalysts are also described.
Claims20
A composite catalyst, comprising:
- a mesoporous silica support which is at least one selected from the group consisting of SBA-15, mesoporous silica foam, and silica sol;
- and
- a catalytic material comprising a bismuth silicate and a transition metal oxide impregnated on the mesoporous silica support,
- wherein the composite catalyst is devoid of molybdenum.
The process of 14, wherein the feed mixture comprises 2-butene, and wherein the process has a butadiene yield of 30-80 wt % relative to a weight of 2-butene.
