A method for processing plastics includes receiving input plastics to be processed. The method further includes driving the input plastics through a reactor chamber having at least two zones each containing heated fluid that is heated to greater temperatures in a subsequent zone such that remaining plastics of the input plastics are exposed to increasingly greater temperatures in each zone of the reactor chamber. The method also includes collecting condensable vapors that flow out of the at least two zones of the reactor chamber. The method further includes condensing the condensable vapors into a liquid condensate. The method also includes removing biochar products from the heated fluid. The method further includes removing contaminants from the reactor chamber.

An optimization method for a directional preparation technique and efficient use of semi-coke for blast furnace injection. Firstly, the volatile and the ash content of target semi-coke are preset, and then the volatile and the ash removal percentages of a raw coal are calculated; after ash removal, several sets of dry distillation carbonization temperatures and carbonization times are obtained according to the volatile removal percentage, and the relationships between a combustion rate, abrasiveness, explosiveness and jet flow property and the carbonization temperature are respectively established to obtain the optimal actual carbonization temperature; and semi-coke for blast furnace injection is obtained at an actual carbonization temperature. The directional preparation is suitable for the semi-coke for blast furnace injection, and an optimal coal-compounding scheme is obtained, thus achieving the efficient and safe injection of blast furnace iron-making fuels, and energy conservation and emission reduction.
