Hydrotreatment of diesel feedstock over Pt-SAPO-31 catalyst: from lab to pilot scale

摘要

High effective hydroisomerization properties of Pt-SAPO-31 catalyst were demonstrated both in laboratory experiments and on pilot scale. Activity of the catalyst is suppressed by sulfur (100-500 ppm), but it may be restored by temperature rise. Long-term run of Pt-SAPO-31 catalyst have confirmed its high activity and stability. Group compositions of feedstock and reaction products were examined by ~1H and ~(13)C NMR method and properties of the catalyst in dependence on reaction properties are discussed.
