A PROCESS FOR THE PRODUCTION OF NEEDLE COKE
The present disclosure relates to a process for the production of needle coke in a delayed coker plant. The needle coke so obtained by the process of the present disclosure has a co-efficient of thermal expansion (CTE) of less than 1.210.sup.6/ C. The process of the present disclosure eliminates the step of hydrotreating of the first feed and second feed for the production of good quality coke. The process of the present disclosure maximizes the production of the needle coke having low CTE and low sulfur content in the delayed coker coke drum.

USING PHOTONICS TO RECOVER CRITICAL MATERIALS FROM AUTOMOTIVE SHREDDER RESIDUE AND SIMILAR MIXED PLASTIC WASTE
Waste feed material, such as Automotive Shredder Residue (ASR) feed material, that includes hydrocarbon materials and inorganic materials is processed using photolysis. A reactor includes a chamber that receives waste feed material including a majority of hydrocarbon material after the substantial removal of inorganic material including metals and minerals. A photonic illumination or photolysis module irradiates the feed material within the chamber of the reactor to decompose the hydrocarbon or hydrocarbon materials within the waste feed material into gases and/or carbonaceous solids. A mechanical movement unit moves the waste feed material within the chamber of the reactor to facilitate exposure of different portions of the feed material to irradiation within the chamber during system operation. A pre-treatment module substantially removes the contained metals and minerals in the waste material from the hydrocarbon material fed to the reactor.
PYROLYSIS PROCESS FOR THE PRODUCTION OF A PYROLYSIS OIL SUITABLE FOR CLOSED LOOP RECYCLING, RELATED APPARATUS, PRODUCT AND USE THEREOF
The present invention relates to the treatment of plastic materials to be used for chemical recycling processes for the enhancement of substantially plastic materials otherwise destined for disposal.
Specifically, the invention relates to a process for the pyrolysis of substantially plastic material to obtain at least hydrocarbons that are liquid at 25 C., comprising the following steps: a) feeding a substantially plastic material to a pyrolysis reactor; b) bringing said material in said pyrolysis reactor to a temperature of between 330 C. and 580 C. in the substantial absence of oxygen and at a pressure of between atmospheric pressure and 13 bara; c) maintaining said material in said pyrolysis reactor for a sufficient amount of time to produce an effluent in the gaseous state; d) partially or fully condensing said effluent in the gaseous state, so as to form at least one fluid comprising hydrocarbons that are liquid at 25 C. and which quantitatively is at least 10% by mass with respect to the mass of substantially plastic material fed; e) carrying out an assessment of at least one property Px of the liquid condensed from said effluent in the gaseous state by means of at least one measurement Ax of the spectrum in transmission, reflection or transflexion on said condensed liquid; f) adjusting at least one process parameter Ox according to said assessment of at least one property Px; g) repeating steps e) and f) iteratively so as to keep the said at least one property Px substantially constant over time.
