Abstract (en)
A process for the catalytic gasification of carbonaceous materials is performed in the presence of a catalyst comprising an added potassium salt of an acid having an ionization constant exceeding 10<-><3>, which salt has relatively poor catalytic activity (compared to the activity of potassium carbonate) and a sodium or lithium compound. The sodium or lithium compound is either a salt of a weak acid having an ionization constant of less than 10<-><3> or a salt of a strong acid that is converted (temporarily or permanently) to a salt of a weak acid having an ionization constant less than 10<-><3>, under the condition of the gasification reactions. High gasification rates may thus be achieved employing catalyst materials which are relatively cheaper than potassium carbonate.
