A multi-stage product gas generation system converts a carbonaceous material, such as municipal solid waste, into a product gas which may subsequently be converted into a liquid fuel or other material. One or more reactors containing bed material may be used to conduct reactions to effect the conversions. Unreacted inert feedstock contaminants present in the carbonaceous material may be separated from bed material using a portion of the product gas. A heat transfer medium collecting heat from a reaction in one stage may be applied as a reactant input in another, earlier stage.

The pyrolysis reactor system for the conversion and analysis of organic solid waste is a dual gas-liquid separation system, allowing for the conversion of organic solid waste, as well as analysis of the conversion products. A pyrolysis reactor is provided for converting the organic solid waste into a solid product and a gas-liquid product mixture through pyrolysis. A source of carrier gas is in fluid communication with the pyrolysis reactor for degrading the organic solid waste. A first gas-liquid separator is in fluid communication with the pyrolysis reactor and receives the gas-liquid product mixture therefrom, separating a portion of gas therefrom. A second gas-liquid separator is in fluid communication with the first gas-liquid separator and receives the gas-liquid product mixture therefrom and separates the remainder of the gas therefrom. The remainder of the gas and the separated liquid are each collected separately from one another, in addition to the char.

A coke manufacturing method includes preparing blended coal by blending coal of at least two types, stirring and mixing the blended coal so as to disintegrate at least a part of pseudo-particles in the blended coal that have been formed by agglomeration of coal particles, and charging the blended coal after stirring and mixing into a coke oven and carbonizing the blended coal so as to manufacture coke.

Co-production a product anode grade coke and a product fuel grade coke is done using a system configured to implement a method that includes: directing an anode grade coker charge material from a tower to a first coke drum set; generating the product anode grade coke using the first coke drum set while directing a first vapor stream from the first coker drum set to the tower; directing a fuel grade coker charge material from a fractionator to a second coke drum set; generating the product fuel grade coke using the second coke drum set while directing a second vapor stream from the second coke drum set to the fractionator; and directing a third vapor stream from the tower to the fractionator while generating the product anode grade coke using the first coke drum set and generating the product fuel grade coke using the second coke drum set.

A biochar production system includes a reactor body, a central rod disposed within the reactor body, a leveling arm extending from the central rod and configured to rotate about the central rod, and a bed level sensor system. The bed level sensor system includes a float configured to move from a resting position on a biomass in the reactor to an ending position upon contact with the leveling arm, and a level sensor coupled to the float via a connector. The level sensor is configured to correspondingly move with the float. A controller is configured to detect bed levels of the biomass within the reactor body, and determine a plurality of sample readings based on the detected bed levels.

A method for preparing a coal, which is used alone or in combination with at least one other coal, or a caking additive as a raw material for coke production. The method includes, before the coal or caking additive is delivered to a coke plant, adjusting a grain size such that the amount of grains with a grain size of 6 mm or more in the coal or caking additive satisfies at least one of a degree of entanglement (ab)/a of 0.20 or more and a portion having a height a of 30 mm or more is 30% or less by mass. The height a is a height of semicoke adhering to a stirrer, the semicoke formed by heating the coal or caking additive in a container while rotating the stirrer, and the height b is a height of the semicoke on an inner wall of the container.
