Methods For Enhancing The Formation Of Mesophase In Pitch Compositions Derived From Hydrocarbon Feedstocks

Nucleation enhancement and/or growth rate improvement of mesophase in pitch compositions derived from hydrocarbon feedstocks can be achieved by: reacting in a reaction zone a blend comprising an isotropic feed and a seeding agent, to produce a reacted pitch having a mesophase content of about 10 vol...

Zusammenfassung:	Nucleation enhancement and/or growth rate improvement of mesophase in pitch compositions derived from hydrocarbon feedstocks can be achieved by: reacting in a reaction zone a blend comprising an isotropic feed and a seeding agent, to produce a reacted pitch having a mesophase content of about 10 vol % to 100 vol %, based on the total volume of the reacted pitch, and a softening point (Tsp) below 400° C.; wherein the seeding agent is about 50 wt % or less, based on the total weight of the blend; wherein the seeding agent has a mesophase content of about 0.01 vol % to 100 vol %, based on the total volume of the seeding agent.
