A Two-Step, Temperature-Staged Direct Coal Liquefaction Process
Abstract—The world crude oil demand is projected to rise to 108.5 million bbl/d by the year 2035. With reserves estimated at 869 billion tonnes worldwide, coal remains an abundant resource. The aim of this work was to produce a high value hydrocarbon liquid product using a Direct Coal Liquefaction (DCL) process at, relatively mild operating conditions. Via hydrogenation, the temperature-staged ...
متن کاملPreparation of Nickel Nanoparticles by Intramolecular Reaction of Nickel(II) Hydrazine Complex in the Solid State at Room Temperature
Ni6(N2H4)6(SO4)4(OH)2(H2O)8](SO4)(H2O)10 complex was prepared according to literature report. The reaction between aforementioned complex via sodium alkoxides as a reactants, were carried out in the solid state. The [Ni6(N2H4)6(SO4)4(OH)2(H2O)8](SO4)(H2O)10 undergoes an intramolecular two electrons oxidation-reduction reaction at room temperature and metallic nickel nanoparticles (Ni1-Ni5) was ...
متن کاملDirect Coal Liquefaction with Fe3O4 Nanocatalysts Prepared by a Simple Solid-State Method
Fe3O4 nanoparticles were prepared by a simple solid-state method under ambient conditions. The obtained nanoparticles, with small size and large surface area, were used as a catalyst for direct coal liquefaction (DCL). The results display that high conversion and oil yield were achieved with the nanocatalysts in direct liquefaction of two kinds of coals, i.e., Heishan coal and Dahuangshan coal....
متن کاملstudying room temperature curing of phenolic resin and their composites
phenolic resins are synthetic low molecular weight thermoset resins which are polymerized and cured to higher molecular weights by condensation method. these resins have high weathering resistance, high oxidative thermal properties and good chemical resistance. phenolic resins can be cured thermally or by acid curing. the most common method of curing phenolic resin is by thermal curing that tak...
متن کاملReaction Engineering of Direct Coal Liquefaction
Direct coal liquefaction has been studied and practiced since the 1930s. It was used in Germany during World War II to produce synthetic fuels when there was no oil allowed into the country. Since then, it has been studied in the United States and many different technologies have been investigated. Since the US is rich in coal resources, this is one way to be energy independent. Most of the dev...
