Hydrotreating reactions of tall oils over commercial NiMo catalyst
Catalytic hydrotreating is an attractive method for upgrading bio-derived oils into renewable feedstocks with less oxygen content, suitable for producing valuable hydrocarbons through various petro-refinery processes. This study evaluates the catalytic activity of a commercial alumina (Al2O3) supported NiMo catalyst for hydrotreating tall oil feeds such as crude tall oil (CTO), distilled tall o...
متن کاملA Study on the Hydrotreating of Coal Hydroliquefaction Residue and its Kinetics
Hydro-conversion of coal hydroliquefaction residue obtained from a 6t/day pilot plant of Shenhua Group in Shanghai was carried out under the hydrotreating condition. The coal hydroliquefaction residue and its product were extracted in sequence with n-hexane, toluene and tetrahydrofuran in a Soxhlet apparatus. The n-hexane soluble fractions increased with the increase of reaction temperature and...
متن کاملThe in-situ TEM Study of Microstructure Alteration of MoS2 under Carburization
Conversional hydrotreating catalysts mostly use Ni-promoted MoS2 as active sites. Modifying conventional hydrotreating catalyst surface of MoS2 by selectively introducing carbon atom into catalyst crystal structure can lead to an improved electronic property, increased capability of hydrogen adsorption and dissociation. Such process will effectively increase catalyst hydrogenation activity and ...
متن کاملHydrotreating of tall oils on a sulfided NiMo catalyst for the production of base-chemicals in steam crackers
This research thesis validates the potential of tall oil as a renewable feedstock for the production of base-chemicals, especially olefins, as conceived in the thermo-chemical bio-refinery concept. The focus was on the use of hydrotreating and steam cracking technologies with different tall oil feedstocks. Particular advances were accomplished in terms of technology development for high yield o...
متن کاملBioleaching of Molybdenum from a Coal Liquefaction Catalyst Residue
bioleaching, molybdenum disulfide, catalyst residue Molybdenum disulfide, MoSz, is used as a catalyst in coal-oil coprocessing. For most processes using molybdenum catalysts to be economical, the molybdenum must be recovered and recycled. Chemical recovery schemes have been devised, but typically recover only a fraction of the molybdenum. There are reports in the literature that bacteria can ox...
