Carbon dioxide reactions occurring during carbon electrode use in the production of aluminum can be decreased by contacting the outer surface of the calcined coke with elemental sulfur prior to the formation of the coke into an electrode.

Carbon electrode for reducing dusting and gasification in an

This invention is directed toward an improved carbon electrode having a coefficient of thermal expansion of less than 3.5.times.10.sup.-7. Composition of the electrode includes needle coke in an amount of from about 60 to 90 weight percent and a quinoline soluble binder pitch in an amount of from about 10 to 40 weight percent, having a ring and ball softening point of from about 94.degree. to 150.degree. C. consisting of a highly aromatic condensation product of a distilled cycle oil extract with an extractant selected from the group consisting of furfural, phenol, B,B'-dichloro diethyl ether, nitrobenzene and sulfur dioxide.

Carbon electrodes having a low coefficient of thermal expansion

Carbon dioxide and air reactivity reactions occurring during carbon electrode use, can be minimized by the use of quench water treated with phosphoric acid following calcination of the coke used to make the electrode.

Reducing carboxy reactivity in coke

An oxydehydrogenation process for producing indene and substituted indenes from indene precursors more saturated than indene is described and comprises contacting said precursor with oxygen and a catalyst comprising cobalt oxide and molybdenum oxide at an elevated temperature above about 300.degree. C. Preferably the reaction is conducted at a temperature of about 500.degree.-650.degree. C. for a period of from 0.1 to about 30 seconds.

Oxydehydrogenation process for preparing indenes

A process for the co-production of indene and styrene from a mixture of cyclopentadiene or dicyclopentadiene and butadiene is disclosed. The process comprises the steps of reacting cyclopentadiene or dicyclopentadiene with butadiene in a Diels-Alder reaction to form a mixture of tetrahydroindene, vinylcyclohexene and vinylnorbornene followed by the recovery of the tetrahydroindene and vinylcyclohexene, and the oxydehydrogenation of the tetrahydroindene/vinylcyclohexene mixture utilizing a composite catalyst comprising cobalt oxide and molybdenum oxide.

Co-production of indene and styrene

A dehydrogenation process for producing indene and substituted indenes from tetrahydroindene or substituted tetrahydroindene is described and comprises contacting said tetrahydroindene or substituted tetrahydroindene with a catalyst comprising cobalt oxide and molybdenum oxide at an elevated temperature for a period of from about 0.1 to 30 seconds. The tetrahydroindene and substituted tetrahydroindenes may be prepared from cyclopentadiene or dicyclopentadiene and a butadiene.
