Abstract: Tungstated zirconium catalysts for paraffin isomerization may comprise: a mixed metal oxide that is at least partially crystalline and comprises tungsten, zirconium, and a variable oxidation state metal selected from Fe, Mn, Co, Cu, Ce, Ni, and any combination thereof. The mixed metal oxide comprises about 5 wt. % to about 25 wt. % tungsten, about 40 wt. % to about 70 wt. % zirconium, and about 0.01 wt. % to about 5 wt. % variable oxidation state metal, each based on a total mass of the mixed metal oxide. The mixed metal oxide has a total surface area of about 50 m2/g or greater as measured according to ISO 9277, and at least one of the following: an ammonia uptake of about 0.05 to about 0.3 mmol/g as measured by temperature programmed adsorption/desorption, or a collidine uptake of about 100 μmol/g or greater as measured gravimetrically.

Abstract: Isotropic pitch compositions may be obtained by reacting an aromatic feedstock comprising one or more aromatic classes with formaldehyde or paraformaldehyde under acidic conditions. Isotropic pitch compositions may comprise: at least two monomers linked with at least one methylene bridge between each one of the at least two monomers, wherein each one of the at least monomers comprises one or more aromatic classes comprising one or more 5-membered rings, 6-membered rings, and any combination thereof; and wherein the isotropic pitch composition has a weight average molecular weight (Mw) of about 300 g/mol to about 1,500 g/mol, a softening point (Tsp) of 90 °C or greater, and a micro carbon residue (MCR) of about 18 wt% or greater, based on the total weight of the isotropic pitch composition.
