摘要： The present invention is directed to novel thermal cracking additive compositions for reduction of coke yield in Delayed Coking process and method for preparing the same. The present invention also provides that the thermal cracking additive compositions of the present invention are in micron-size and nano-size. Further, the present invention provides a process of thermal cracking of heavy petroleum residue used in petroleum refineries using Delayed Coking process to produce petroleum coke and lighter hydrocarbon products with decreased coke yield and increased yield of liquid and/or gaseous products.
