The invention relates to a method for recovering hydrocarbons from plastic wastes, in particular polyolefin-rich waste, by means of purely thermolytic cracking without the use of catalysts, comprising melting the plastic waste in two heating devices (3) and (4), wherein a recycle stream derived from the cracking reactor (5) and purified in a separator system (8, 9) is admixed with the molten plastic waste from the heating device (3). The mixed plastic stream is further heated in the second heating device (4), and from there is guided into the cracking reactor (5), where the plastic materials are cracked, and by means of subsequent distillation are separated into diesel and low boilers. A special entry system allows the prior separation of water and acidic gases, and the saving of inert gas. The invention further relates to a system for carrying out the method.

A method is provided for inputting thermal energy into fluidic medium in a process or processes related to oil refining and/or petrochemical industries by at least one rotary apparatus comprising a casing with at least one inlet and at least one exit, a rotor comprising at least one row of rotor blades arranged over a circumference of a rotor hub mounted onto a rotor shaft, and a stator configured as an assembly of stationary vanes arranged at least upstream of the at least one row of rotor blades. In the method, an amount of thermal energy is imparted to a stream of fluidic medium directed along a flow path formed inside the casing between the inlet and the exit by virtue of a series of energy transformations occurring when said stream of fluidic medium passes through stationary and rotating components of said rotary apparatus, respectively. The method further comprises: integration of said at least one rotary apparatus into a heat-consuming process facility configured as a refining and/or petrochemical facility and further configured to carry out heat-consuming process or processes related to refining of oil and/or producing petrochemicals at temperatures essentially equal to or exceeding 500 degrees Celsius (° C.), and conducting an amount of input energy into the at least one rotary apparatus integrated into the heat-consuming process facility, the input energy comprises electrical energy. A rotary apparatus and related uses are further provided.

Various embodiments that pertain to fuel processing are described. A fuel processor can produce an endothermic reaction that cools a substance and produces a processed fuel from a raw fuel. A generator can employ the processed fuel to produce an electricity. The generator can supply the electricity to a load that uses the electricity to function. The load can become hot due to its functioning and can benefit from being cooled. The substance cooled by the fuel processor can cool load and in the process the substance can rise in temperature. This warmer substance can be transferred to the fuel processor to be cooled again and this cycle can continue. Further, the fuel processor can use the warmer substance to achieve the endothermic reaction.

A process for producing syngas and olefins includes the steps of feeding a catalytic partial oxidation (CPO) reactant mixture having oxygen, first hydrocarbons, and optionally steam to a CPO reaction zone having a CPO catalyst such that at least a portion of the CPO reactant mixture reacts, via an exothermic CPO reaction, to produce syngas having hydrogen (H.sub.2), carbon monoxide (CO), carbon dioxide (CO.sub.2), water, and unreacted first hydrocarbons. The syngas is characterized by a molar ratio M defined as (H.sub.2−CO.sub.2)/(CO+CO.sub.2). The method further includes feeding a cracking zone feed having second hydrocarbons to a cracking zone such that at least a portion of the second hydrocarbons undergoes an endothermic cracking reaction to produce a cracking zone product stream having olefins, hydrogen, and unreacted second hydrocarbons; and cooling the CPO reaction zone by heating the cracking zone while cooling the CPO reaction zone via heat transfer between the CPO reaction zone and the cracking zone.

A process for performing high temperature reactions includes introducing reactants into a reactor vessel, generating a high temperature within the reactor vessel, exposing a first portion of the reactants to the high temperature, and reacting the first portion of the reactants based on contact with the high temperature to produce one or more products. The high temperature is higher than a lower temperature of a wall of the reactor vessel, and a temperature gradient is generated between the high temperature and the lower temperature of the wall. A second portion of the reactants are not exposed to the high temperature, and the second portion of the reactants do not react.
