The present disclosure relates to a method of producing metallurgical coke from a combination of non-coking and non-metallic carbon-based microwave susceptor. The method is energy efficient, economical, and environmentally friendly. The present disclosure also relates to metallurgical coke having improved coke quality, such as improved coke strength after reaction.

Process and apparatus that integrate continuously the processes of pyrolysis in a rotary drum at average temperatures of 300 to 500 C. and gasification in a moving-grate gasifier at average temperatures of 500 to 800 C. to produce a mixture of gases originating from the processes of pyrolysis and gasification of waste and the derivatives thereof. The mixture of gases called waste-derived combustible gases is continuously passed through a Venturi system or an exhaust system and can be directed to a system for combustion or treatment and separation of the combustible fractions for subsequent energy recovery. Waste in the form of powder, fines, slurries, pastes or liquids can be thermally treated individually or in blends with other waste such as municipal solid waste, commercial waste or industrial waste, with additional energy recovery.

A method and an apparatus for CO.sub.2 negative production of heat and power in combination with hydrogen (CHPH) from carbonaceous raw material using microwaves as a heating source. The invention provides an extremely energy effective and homogenous heating of biochar enabling production of hydrogen in significant amounts. The apparatus comprises several closed vessels and is suitable for H.sub.2 production on a small scale and locally.

A pyrolysis plant comprising a reactor for producing pyrolysis gas from biomass is disclosed. The reactor comprises one or more reaction channels thermally connected to at least one heating circuit, which is configured to heat the reaction channels to a temperature that is high enough to gasify the biomass, where the reactor comprises a feed section configured for feeding the biomass into the reaction channels. Each reaction channel constitutes a heating circuit integrated in the reaction channel, wherein the heating circuit comprises a gas mixture unit and a plurality of input nozzles arranged and configured to introduce a mix of oxygen and CO.sub.2 from the gas mixture unit into the reaction channel.

Methods and systems for coking coal blends to produce foundry coke products are disclosed herein. Methods for producing coke products can include charging a coal blend into a coke oven; and heating the charged coal blend such that a crown temperature of the coke oven is greater than a lower bound coking temperature. The pyrolysis duration begins when the crown temperature of the oven is greater than the lower bound coking temperature, and ends when the crown temperature of the oven is less than the lower bound coking temperature.

Systems and methods for producing green hydrogen from a source material (e.g., biowaste) are contemplated. The source material is at least partially dehydrated to produce a dried intermediate and recovered water. The dried intermediate is pyrolyzed to produce syngas and a char. The recovered water is electrolyzed to produce oxygen and green hydrogen.
