  • Patent number: 4255162
    Abstract: Sulfur-containing fuels are converted to substantially sulfur-free combustible gas in an integrated process involving part combustion in a dense phase fluidized conversion bed of particles comprising alkaline earth metal oxides. An oxygen-containing gas is passed into the base of the bed to maintain a relatively high fuel/air ratio. Sulfur is chemically fixed in the particles by reaction to form alkaline earth metal sulfide. Particles containing alkaline earth metal sulfide are circulated from one region of the conversion bed to one region of a dense phase fluidized regeneration bed operated at a higher temperature and fluidized by passing into the base thereof an oxygen-containing gas which exothermically regenerates chemically active alkaline earth metal oxide from the sulfide liberating gases which have a low oxygen content and a relatively high content of sulfur moieties (e.g. SO.sub.2).

  • Patent number: 4251496
    Abstract: A combination process is provided in which a gaseous mixture comprising SO.sub.x and NO.sub.x is reacted with cerium oxide at a temperature ranging from about 500.degree.

C. to about 700.degree. C. in the presence of ammonia at net oxidizing conditions to reduce the NO.sub.x content of the gaseous mixture. The process may be conducted in one reaction zone or in a plurality of reaction zones. The cerium oxide reactant may be regenerated by reacting cerium oxysulfate with a reducing gas such as hydrogen.
