Abstract
A composition may include: a pitch composition having an MCR of greater than 30 wt. %, a softening point between about 30° C. to about 240° C., and wherein the pitch composition is 100 wt. % soluble in toluene.
Claims25
A composition comprising:
- a pitch composition having a microcarbon residue “MCR” of greater than 30 wt. %, a softening point between about 30° C. to about 240° C., and wherein the pitch composition is 100 wt. % soluble in toluene, wherein MCR is measured according to ASTM D4530 (2020).

A method comprising:
- introducing an aromatic feedstock into a deasphalting unit;
- and
- deasphalting at least a portion of the aromatic feedstock to produce a deasphalted oil and a pitch composition,
- wherein the pitch composition has a microcarbon residue “MCR” of greater than 30 wt. %, a softening point between about 30° C. to about 240° C., and wherein the pitch composition is 100 wt. % soluble in toluene.

A method comprising:
- introducing an aromatic feedstock produced from a solvent assisted tar conversion (SATC) process into a deasphalting unit;
- deasphalting at least a portion of the aromatic feedstock with a C4-C7 solvent to produce a deasphalted oil and a deasphalted rock;
- and
- blending the deasphalted rock with an aromatic feedstock to produce a pitch composition with an microcarbon residue “MCR” of greater than 30 wt. %, a softening point between about 30° C. to about 240° C., and wherein the pitch composition is 100 wt. % soluble in toluene.
