How we do it?
The high efficiency auger type pyrolysis reactor (MM-P2C): This design comes from the first stage of the two-stage gasifier, but it can be run as the core of a pyrolysis-only reactor. The design features a unique heat transfer principle, which enables efficient heating of the feedstock in the machine using only the residual pyrogas from the process. The picture below shows the pyrolysis unit that processes approximately 11 tonnes of feedstock daily, at our current plant in Ahmedabad, India.
The MASH pyrolysis technology was developed in collaboration with Ulrik Birk Henriksen at DTU Chemical Engineering and it was designed based on a simple idea: Create a flexible platform for feedstock pyrolysis that at the same time is modular and easy to place and move. As such, the ME-P2C constitutes the largest possible reactor that could be mounted in a 20' shipping container, meaning an unprecedented amount of processing capacity is available in a very compact form. The system is highly optimized for heat recovery and is built for continuous operations and produces pyrogas which is used to heat and run the process itself – making it self-sufficient.
The classical issue with pyrolysis derived fuel is high acidity, high oxygen content and – as a consequence of both – short shelf life and poor miscibility with other oils. Also, the calorific value of pyrolysis oils tends to be significantly lower than what is expected by industry. MASH Makes has addressed this by carefully selecting feedstocks for their pyrolysis processes and thereby ensuring that the outputs are appropriate (e.g. low oxygen content).
