Latest Patents

Callen’s patent, “Methods for Enhancing the Formation of Mesophase in Pitch Compositions Derived from Hydrocarbon Feedstocks,” describes a process intended to improve mesophase nucleation or growth in pitch.

The method reacts a blend of an isotropic feed and a seeding agent in a reaction zone. The resulting pitch has a mesophase content of about 10 to 100 volume percent and a softening point below 400°C. The seeding agent makes up no more than about 50 weight percent of the blend and has a mesophase content of about 0.01 to 100 volume percent.

Career Highlights

Callen’s listed patent reflects work on controlling mesophase formation in hydrocarbon-derived pitch. The disclosed approach uses a seeding agent to promote nucleation or improve the growth rate of mesophase in the reacted pitch.
