摘要:
This invention relates to an integrated gasification apparatus for carbonaceous fuel, wherein high-pressure steam produced during a gasification process of carbonaceous fuel is directly used to dry the carbonaceous fuel, and steam obtained through the drying process is directly used in a water gas shift process.
摘要:
Provided is a carbon fuel pneumatic dryer in which synthesis gas generated in a reactor is fed and cooled, including: a feeding part formed as a narrow pipe, via which synthesis gas and carbon fuel are fed; a drying part formed as a pipe having a larger diameter than the feeding part, in which the hot synthesis gas fed via the feeding part is cooled and the moisture content of the carbon fuel is lowered; and a conveying part formed as a pipe having a smaller diameter than the drying part such that the flow velocity of the synthesis gas and the carbon fuel having passed the drying part is increased, wherein the conveying part includes a bend so that the flow direction of the synthesis gas and the carbon fuel is changed.
摘要:
Embodiments of the invention provide filtering structures and methods. At least filtering structure includes a filtering medium for removing impurities from a gas produced by gasifying coal or biomass, and a catalyst for converting methane and carbon dioxide into synthesis gas by a dry reforming reaction and a steam reforming reaction. The filtering medium, according to various embodiments, is coated with the catalyst.
摘要:
The present invention relates to a gasification process for efficiently co-producing synthesis gas and high-grade coal from water-containing coal, and to an integrated drying and gasification system for realizing the same.
摘要:
The present invention relates to a gasification process and system, wherein a dryer integrated with a water-gas-shift catalyst is disposed in front of a gasifier.
