PROCESS FOR CATALYTIC PRODUCTION OF PROPANOL
The present disclosure is related to a multistep process for producing renewable gasoline components from a glyceride containing feedstock. The glycerides are split to provide a stream containing fatty acids, or esters of fatty acids, and another stream containing glycerol and water. Glycerol, preferably as crude glycerol recovered from splitting, is next converted to propanols at vapor phase, providing a renewable propanol gasoline component. Another renewable gasoline component is obtained from hydroprocessing of the fatty acids or esters thereof, as a renewable paraffinic naphtha component. Blending the renewable components can provide a novel 100% renewable gasoline.

Method for producing monocyclic aromatic hydrocarbons
A method of producing monocyclic aromatic hydrocarbons includes bringing a light feedstock oil having a 10 vol % distillation temperature of 140° C. to 205° C. and a 90 vol % distillation temperature of 300° C. or lower, which has been prepared from a feedstock oil having a 10 vol % distillation temperature of 140° C. or higher and a 90 vol % distillation temperature of 380° C. or lower, into contact with a catalyst for monocyclic aromatic hydrocarbon production containing a crystalline aluminosilicate, in which a content ratio of monocyclic naphthenobenzenes in the light feedstock oil is adjusted by distillation of the feedstock oil such that the content ratio of monocyclic naphthenobenzenes in the light feedstock oil is higher than a content ratio of monocyclic naphthenobenzenes in the feedstock oil.

Hydroprocessing of hydrocarbons using delaminated zeolite supports as catalysts
Provided is an improved hydroprocessing process allowing one to realize superior isoselectivity. The process comprises contacting a feed comprised of normal hydrocarbons under hydroprocessing conditions with a catalyst comprising delaminated SSZ-70. The delaminated SSZ-70 has been found to provide unexpected improvements in the catalysis of hydroprocessing hydrocarbons. Delaminated SSZ-70 offers a zeolite layer with a single unit cell of thickness in one dimension, allowing an elimination of mass transfer in comparison with non-delaminated SSZ-70.
