Abstract:
A method and catalyst for reacting hydrogen with aromatic hydrocarbons, with sulfur-containing acyclic and heterocyclic compounds, and with nitrogen-containing acyclic and heterocyclic organic compounds, the catalyst being comprised essentially of supported molybdenum and arsenic in their reduced forms.
Abstract:
HEAVY HYDROCARBON OILS, RESIDUAL FRACTIONS AND OTHER CARBONACEOUS MATERIALS ARE CONVERTED TO USEFUL LIQUID PRODUCTS BY CONTACTING WITH A NICKEL SPINEL CATLAYST PROMOTED WITH A BARIUM SLAT OF AN ORGANIC ACID.
Abstract:
SHEAR-STABLE, HIGH VISCOSITY INDEX LUBRICATING OIL FORMULATIONS ARE FORMED BY THE ADDITION OF A SMALL AMOUNT OF A HYDROGENATED RANDOM BUTADIENE-STYRENE COPOLYMER HAVING A BUTADIENE CONTENT OF 30 TO 44 WEIGHT PERCENT.
Abstract:
Alkenes and/or alkadienes are contacted with molecular oxygen and an oxidative dehydrogenation catalyst consisting essentially of phosphorus, iron, and oxygen, with the iron-to-phosphorus atom ratio being in the range of about 2:1 to about 20:1.
Abstract:
Aromatics are selectively partially hydrogenated to substantial amounts of cyclic olefins by contacting the aromatics under hydrogenation conditions with hydrogen and with an aqueous dispersion of a solid ruthenium-containing catalyst promoted with a modifying amount of a transition metal and wherein the aqueous dispersion is maintained at essentially neutral or acid pH conditions.
Abstract:
A TWO-STAGE HYDROGENATION AND SEPARATION PROCESS OF A CYCLOPENTADIENE SOURCE FOR THE MANUFACTURE OF A SUBSTANTIALLY DIOLEFIN FREE, HIGH PURITY CYCLOPENTENE SUITABLE FOR POLYMERIZING.
