Processes for producing liquid fuels from a mainly organic starting material with a reduced content in water and/or with a reduced content in solids are disclosed. The mainly organic starting material can be at least partially liquified and optionally further dewatered. The obtained at least partially liquid fraction can be thereafter used as feeding stream that is submitted to a pyrolysis treatment resulting in a solid gas fraction allowing the recovering of a liquid fuels after a controlled liquid solid separation treatment. There are also provided various other processes for producing liquid fuel from waste hydrocarbon and/or organic material as well as reactors, apparatuses, uses and managing systems thereof.

A rotary kiln capable of segmented temperature control includes a kiln body, a kiln head cover, a kiln tail cover, and a bottom base. A drive device is disposed between the bottom base and the kiln body. The kiln further includes a first fuel supply pipe having a supply segment, a connecting segment, and a rotating segment. The supply segment is fixedly disposed on an outer side wall of the kiln body. The rotating segment is disposed coaxially with the kiln body and connected to a fuel supply source through a rotatory joint. The supply segment communicates with the rotating segment through the connecting segment. Multiple groups of combustion components are disposed on the outer side wall of the kiln body, and a fuel inlet of each combustion component is connected to the supply segment of the first fuel supply pipe through a branch pipe.
