摘要： A mesophase pitch suitable for carbon products, particularly for carbon fibers, which has a mesophase content of at least 40%, preferably at least 60%, and a larger mesophase domain, is produced by adding at least one part by weight of at least one of an alcohol and a phenol to 100 parts by weight of heavy bitumens, subjecting the resulting mixture to pretreatment by heating at least at 250.degree. C., and then subjecting the pretreated mixture to heat treatment until mesophases are formed.

摘要： Pitch is produced continuously by heat treating a heavy hydrocarbon oil at a temperature of 350.degree. to 500.degree. C successively in two or more reactors connected in series, outlet to inlet, recirculating, at the same time, one portion of the liquid output substance from at least one reactor into that reactor, and introducing the output substance (molten pitch) of the final reactor into an after-treatment chamber of duct shape with an inactive atmosphere sealed therewithin thereby to cool the output substance.

摘要： The present invention provides a densifying agent adopted a total weight of a refined pitch which is 100 as a basis, the composition of the refined pitch includes 19-30 toluene insolubles (TI) by weight, 0.1˜0.3 quinoline insolubles (QI) by weight, 0˜0.001 ash by weight and 18˜30 quinoline solubles (QS) by weight, in which the temperature of the softening point of the refined pitch is in the range of about 120° C. to 140° C. Accordingly, the amount of the toluene insolubles (TI) and the small amount of the quinoline insolubles (QI) can be mixed with the carbon-based material to increase the density of the carbon-based material, and the content of the quinoline solubles (QS) is used for adjusting the binding effect of the densifying agent with the binder.

摘要： A method (100) of recovering tar from the gasification of a carbonaceous feedstock includes gasifying (12) a carbonaceous feedstock (14) to produce a raw gas (20) which includes at least CO, H2, tar and entrained solids, the raw gas (20) being at a temperature of at least 250° C. and a pressure of at least 15 bar (g). The raw gas (20) is quenched and washed (22) with a quench liquid (24) producing a solids-containing liquid stream (32) which includes tars, the solids-containing liquid stream being at a temperature of at least 150° C. and a pressure of at least 15 bar (g). Solids (56) are separated (46) from the solids-containing liquid stream (32) to provide a tar recovery stream (102). The tar recovery stream (102) is treated by at least cooling (34) and pressure expansion (36) thereof to produce a tar stream (58).
