High-quality graphite/needle grade coke is produced with reduced impurity levels and improved coefficient of thermal expansion using an integrated hydrotreatment, catalytic cracking and coking reaction sections, employing a combination of highly paraffinic hydrotreated VGO stream and aromatic CLO stream, which is thereafter processed in a delayed coking section.

A catalyst structure includes a porous support structure, where the support structure includes an aluminosilicate material and any two or more metals loaded in the porous support structure selected from Ga, Ag, Mo, Zn, Co and Ce. The catalyst structure is used in a hydrocarbon upgrading process that is conducted in the presence of methane, nitrogen or hydrogen.

The present invention provides a process for a production of light olefins and aromatics from cracked light naphtha by selective cracking. The present invention thus provides a process for up grading cracked olefinic naphtha to high value petrochemical feed stocks. This process is based on catalytic cracking in which the catalyst activity is optimized by depositing coke for production of light olefins and aromatics. The proposed process has high flexibility and can be operated either in maximizing olefins as reflected from the PIE ratio or in maximizing aromatics (BTX) at different modes of operation depending upon the product requirement.
