Abstract The present invention provides preparation method of high softening point fiber spinning asphalt and refined carbon fiber asphalt material by using ethylene cracked tar as raw material. Ethylene cracked tar is produced through atmospheric distillation and decompress distillation process to produce resin asphalt and fiber spinning asphalt with softening point as high as 200-250 deg.c, and the resin asphalt is further produced through thermal polymerization and separation reaction in anaerobic and gas stripping conditions into refined carbon fiber asphalt material. It has simple production process and low cost and the product can meet the requirement of spinning.
