The present invention relates to delayed coking of heavy petroleum residue producing petroleum coke and lighter hydrocarbon products. The invented process utilize a pre-cracking reactor and a reactor furnace for mild thermal cracking of the feedstock and an intermediate separator, before being subjected to higher severity thermal cracking treatment in a coker furnace and a coking drums, resulting in reduction in overall coke yield.

A device for the material treatment of raw materials includes a heating system, a distillation unit, a reaction unit, and a control device. The reaction unit can be charged with the raw materials for treatment. The heating system can be opened to be charged with the reaction unit, and closed. An exhaust gas line is provided to discharge exhaust gases from the reaction unit. The distillation unit has a cooling section with a device for forced cooling. Temperature sensors are provided in the region of the heating system and the distillation unit. An extraction device extracts gases from the reaction unit and generates negative pressure inside the reaction unit. The temperature sensors and the extraction device are connected to the control device. The device can be operated for the material treatment of raw materials to produce, for example, carbon.
