A method for upgrading heavy oil by using a coke production byproduct comprises the steps of: producing a mixed solution by mixing a coke production byproduct and heavy oil; and hydrogenating the mixed solution under a hydrogenation catalyst, wherein the present disclosure is economical and effective by being able to reduce the amount of coke formation and significantly reduce the partial pressure of added hydrogen by using the coke production byproduct as a hydrogen donor.

Method for lightening heavy oil by using coke production byproduct

The present invention relates to a method for upgrading heavy oil by using byproducts of coke production, and particularly provides a method for upgrading heavy oil comprising the steps of: a) mixing heavy oil with byproducts of coke production to produce a mixed liquid: and b) subjecting the mixed liquid to pyrolysis, the method allowing reduction of the amount of coke generated and thus being economical and effective.

Method for upgrading heavy oil by pyrolysis using byproducts of coke production

The present invention relates to a catalyst precursor for forming a molybdenum disulfide catalyst through a reaction with sulfur in heavy oil and to a method for hydrocracking heavy oil by using same. According to the present invention, the yield of a low-boiling liquid product with a high economic value in the products by heavy oil cracking can be increased, and the yield of a relatively uneconomical gas product or coke (toluene insoluble component), which is a byproduct, can be significantly lowered.

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.

Integrated drying and gasification process for simultaneously producing synthetic gas and high rank coal

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.

Pneumatic conveying dryer for carbon fuel

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.

Gasification combined facility for carbon fuel including pneumatic conveying dryer

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.

The present invention provides a top-feeding double-swirl type gasifier: a feed line through which pulverized coal is supplied by nitrogen; a distributor for dividing the pulverized coal supplied; a plurality of burner nozzles for supplying the pulverized coal, divided in the distributor, and an oxidizer; a pressure reactor in which the pulverized coal and the oxidizer react with each other to produce a flow of synthesis gas; and a swirl generator for imparting a swirling force to the oxidizer which is fed into the pressure reactor, the gasifier further comprising a slag cooling and storing container placed beneath the pressure reactor. Each of the burner nozzles consists of a triple tube having a circular cross section. The pulverized coal and carrier gas are supplied to the most central region of the burner nozzle, and an oxidizer is supplied to an annular regionsurrounding the central region.

Top-feeding double-swirl type gasifier

The present invention relates to a method for gasification of carbon-containing materials, and more specifically, to a method for gasification of carbon-containing materials which allows an increase in carbon efficiency and a reduction in carbon dioxide emission, comprising the steps of: gasification of carbon-containing materials to methane; thermal decomposition of CHto C and H; and conversion of COto CO using the carbon produced during the decomposition. The method of the present invention greatly increases carbon efficiency and reduces the generation of carbon dioxide.
