  • PROCESS FOR PRODUCTION OF NEEDLE COKE FROM COAL TAR PITCH AND PETROLEUM STREAMS
    Publication number: 20260042966
    Abstract: The present invention relates to a process for needle coke production by co-processing coal tar pitch (CTP) with petroleum streams. The process utilizes a ‘multi-residence time mild thermal cracking’ of coal tar pitch with petroleum streams (CLO, PFO) followed by solvent-assisted selective separation of undesirable quinoline insoluble (QI) and solid catalyst fines from the mixed pitch and delayed coking thereafter to produce needle coke. The solvent employed for feedstock purification is a mixture prepared from an aromatic solvent which is a lighter fraction formed by mild and severe thermal cracking of mixed feedstock, an aliphatic solvent and a polar extraction solvent.
