Opening
On the Xilingol grassland, distance is the first fact of any industrial operation. Towns sit far apart across open pasture, cold arrives early and stays late, and every ton of fuel, feedstock, or product crosses that distance twice - in and out. A plant in such a place stands or falls on two questions: how much of its own energy it can supply to itself, and how its operating rhythm fits remote logistics. This 2020 project - the most recent entry in the Jinpeng project archive - answers both with a deliberately modest configuration: two 12 TPD batch reactors on the grassland.
Project Background & Configuration Logic
The configuration was designed for a remote site rather than an industrial catchment. Xilingol is not a tire-manufacturing region, so waste tires must be gathered from scattered towns, vehicle fleets, and livestock operations across the grassland - a dispersed flow that two batch units at 12 TPD design capacity each can absorb.
The batch production model suits this environment as much as the scale. Each reactor follows a cycle of loading, heating, pyrolysis, cooling, and discharge, creating natural windows between batches that can align with the arrival of feedstock trucks and the departure of product loads - planning that matters when a missed delivery window means waiting days rather than hours. The design logic is not "process as much as possible as fast as possible" but "keep the process fed, heated, and moving across long distances without interruption."
Core Technology & Production Analysis
Heating the Plant from Its Own Process Gas
In batch tire pyrolysis, the feedstock decomposes in a horizontal rotating reactor under an inert, micro-negative-pressure atmosphere, with no direct flame contact. The volatile fraction passes through condensation: the condensable portion becomes pyrolysis oil, and the lighter, non-condensable gas remains. On a site where delivered fuel is a logistics cost rather than a utility connection, this gas is central to the energy self-supply logic: it may be returned to the heating system where the installed design and operating conditions permit, so the plant's own process output contributes to its heating duty instead of every megajoule arriving by truck. Its effect in operation depends on the installed arrangement, feedstock, and operating conditions - a design intention, not a measured performance claim.
A Batch Schedule in a Cold Climate
The Xilingol winter is long, and cold touches a pyrolysis site in specific places: condensation efficiency depends on cooling capacity, hot solids are harder to handle at low temperatures, and water and product storage need freeze-aware design. The batch cycle - roughly 22 to 24 hours from loading to discharge - has a practical consequence: each reactor's schedule can be arranged so demanding work falls at practical times, and the two units can run offset, so one reactor's loading or discharge need not coincide with the other's. Labor, cooling, and logistics demand stay even.
Intake Across a Sparse Catchment
Whole or cut tires are loaded into the reactor in batches; this plant type needs no shredding into crumb. That simplicity matters at a remote site: no preparation step demanding its own power, machinery, and maintenance. The planning problem becomes intake volume and timing rather than preparation: with population centers dispersed, tire volumes accumulate slowly in each town, and seasonal roads constrain when they can move. The two-unit scale was sized so a practical number of collection trips, not an industrial stream of inbound trucks, keeps the plant fed, with storage for feedstock and products absorbing the gap between catchment supply and reactor demand.
Long-Range Delivery: Equipment In, Products Out
Delivering two complete reactor lines to a grassland site is itself a logistics exercise: the equipment travels from Shangqiu across several provinces, the final leg on roads serving a thinly populated region. Installation guidance and operator training were part of the delivery scope. On the output side, the recovered streams - pyrolysis oil, recovered carbonaceous material, and steel wire - travel back the same way. Pyrolysis oil is a fuel oil-grade stream, not a finished diesel; whether it is consumed locally or transported onward is an economic decision for the site. The recovered carbonaceous material's value likewise depends on testing and, where required, further processing.
The Latest Entry in the Archive
The Xilingol project is the newest entry in Jinpeng's archive series of batch tire installations from 2017 to 2020, and it is instructive precisely as the last snapshot. The earliest entries show two-unit plants entering new regions; the middle years show the same configuration scaling to six and ten reactors in denser markets. Xilingol returns to the two-unit form at the far end of the spectrum in remoteness - the smallest configuration in the least connected location. Read together, the archive shows a pattern: configuration follows the catchment and the site, and remoteness is answered with scale, schedule, and energy logic rather than with larger machinery.

What the Project Demonstrates
This project demonstrates that a batch tire pyrolysis configuration can be designed around the constraints of a remote, cold-climate site rather than the conveniences of an industrial cluster. The two-unit scale fits a dispersed feedstock catchment; the batch schedule provides windows that align with long-distance logistics; and the gas-return arrangement embodies an energy self-supply logic that reduces dependence on delivered fuel, subject to the installed design and operating conditions. For a prospective client in a similar position - far from fuel supply, feedstock scattered, winters long - this entry is the reference case: modest scale, deliberate scheduling, and a heating design that lets the process contribute to its own energy. Evaluators should watch the gas-return arrangement, intake and product storage planning around catchment and seasons, and the scheduling that keeps one unit's cycle from stranding the other.
