摘要:
A method for producing pressed articles containing coal particles, pressed articles obtained from such method, and the use of such pressed articles in methods for producing pig iron in a fixed bed or for producing carbon carriers for methods for producing pig iron in a fixed bed, are provided. To this end, a partial amount of the coal particles to be processed into pressed articles is impregnated with a substance before the material to be processed into pressed articles is mixed with a binder system containing water and finally being processed into pressed articles.

Methods for pyrolyzing asphaltene material includes providing a composition including from 50 to 90 wt % asphaltene material and from 50 to 10 wt % inert material, and pyrolyzing the composition. The presence of the inert material can help to ensure that the asphaltene material does not interfere with the pyrolyzing process and equipment. Method of forming asphaltene pellets can also be used in order to improve asphaltene pyrolysis.
摘要:
At least one embodiment of the disclosure is directed to a method of producing a lignocellulose-based product with reduced contents of hemicellulose, chlorine, sulfur and alkali and alkaline earth metals. A biomass having up to 60% by weight of moisture prior to steam treatment is steam treated. A lignocellulose-based product with reduced contents of hemicelluloses, chlorine, sulfur and alkali and alkaline metals is produced.
摘要:
In a method for producing pressed articles containing coal particles, before being mixed with a binder system containing water, at least a subset of the coal particles is subjected to at least two impregnation steps in which it is impregnated with at least one substance. The pressed articles may be used, for example, in methods of pig iron production in a packed bed or in methods for producing carbon carriers for methods of pig iron production in a packed bed.

Disclosed herein are a method for solidifying solid fossil fuel and a solidified material obtained thereby. The solidified material is prepared by mixing at least one solid fossil fuel with 5-8 parts by weight, based on 100 parts by weight of the solid fossil fuel, of a solidifying agent, and 1-4 parts by weight, based on 100 parts by weight of the solidifying agent, of aqueous acrylic resin. When this solidifying method is used, a solidified material, which can maintain the durability and high-temperature stability of a solidified material according to the prior furnace process using only coking coal as a raw material and has high heating value, can be prepared using a single solid fossil fuel or mixture thereof, including bituminous coal, anthracite coal and powdery coke.
摘要:
The present invention provides a method and apparatus for agglomerating hydrophobic particles from a feed slurry. The method comprises adding a binder to a feed stream and conveying the feed stream and binder to an agglomerating device. The binder comprises 50% or more by volume of a non-hydrophobic substance. A high shear is applied to the feed stream and the binder in the agglomerating device to cause the hydrophobic particles to collide and bind to the binder, thereby agglomerating the hydrophobic particles. The agglomerated hydrophobic particles and the binder are removed from the feed stream. A method and apparatus for dewatering an agglomerated product is also provided, the agglomerated product comprising agglomerated hydrophobic particles held together by a binder comprising 50% or more by volume of a non-hydrophobic substance.
摘要:
Disclosed herein is a solidifying composition, which is added to a single solid fossil fuel or a mixture thereof to solidify the solid fossil fuels. The solidifying composition contains 34-52 wt % of straight asphalt, 0.1-0.3 wt % of an emulsifier for asphalt, 0.2-0.4 wt % of hydrochloric acid, 0.03-0.05 wt % of calcium chloride, and the balance of water. When this solidifying composition is used, a single solid fossil fuel or mixture thereof, including bituminous coal, anthracite coal and powdery coke, can be used as a raw material for coke. Also, even when the prior coke equipment, incurring a high equipment cost, is not used, it is possible to prepare coke, which can maintain the durability and high-temperature stability of coke prepared using the prior coking coal as a main raw material and which has a high heating value.
