A system for processing a material includes a pre-processing module configured to receive the material, mechanically stress the received material, and output the mechanically stressed material. The system also includes a pyrolysis module communicatively coupled to the pre-processing module and downstream of the pre-processing module. The pyrolysis module is configured to receive the mechanically stressed material from the pre-processing module and to perform a pyrolysis process on the received mechanically stressed material, thereby to produce one or more pyrolysis products.

A method for manufacturing coke having a high strength and excellent extrusion capability. The method includes a preparing step of blending two or more coal brands to prepare a coal blend, a stirring and mixing step of stirring and mixing the coal blend to disintegrate at least a part of pseudo-particles that have been formed by agglomeration of coal particles in the coal blend, and a carbonizing step of charging the stirred and mixed coal blend into a coke oven to carbonize the stirred and mixed coal blend. Additionally, a mixing apparatus is used in the stirring and mixing step that has a capability of controlling a degree of mixing of the coal blend to be 0.85 or more at 60 seconds after start of a mixing operation. The degree of mixing is calculated by the following equation (1):

degree of mixing=(σC.sub.0−σC)/(σC.sub.0−σCf)  (1).

A coke extrusion force estimation method includes: measuring irregularities on an inner wall surface of a carbonization chamber to acquire an oven wall profile; estimating an outer shape of a coke produced in the carbonization chamber based on the oven wall profile; defining an active state for a side surface position of the coke at which a coke width is smaller than an oven width and defining a passive state for a side surface position of the coke at which a coke width is larger than an oven width based on the oven wall profile and the estimated outer shape; and calculating oven wall friction force for each side surface position of the coke using a previously set apparent Young's modulus of the coke in accordance with definition of the active state or the passive state to estimate the extrusion force based on the oven wall friction force.
