Effects of Molecular Composition and Carbonization Reactivity of FCC Decant Oil and Its Derivatives on Mesophase Development
Introduction FCC decant oil is the primary feedstock to delayed coker to produce needle coke, a premium carbon precursor to synthetic graphite electrodes. Mesophase development during coking, determines the graphitizability of the needle coke product. Mesophase development, in turn, depends on the molecular composition of the feedstocks [1,2]. In a commercial delayed coking unit, liquid-phase c...
متن کاملPreparation of mesophase pitch by aromatics-rich distillate of naphthenic vacuum gas oil
Two aromatics-rich distillates R1 and R2 with different properties from naphthenic base vacuum gas oil were used for preparing mesophase pitch through high-pressure thermal treatment. 1H-NMR, FT-IR and VPO were employed to characterize the structural parameters of the raw materials. The products' optical texture and molecular structure were analyzed by polarized light optical microscopy, 1H-NMR...
متن کاملProduction of Mesophase Pitch from Coal Tar and Petroleum Pitches using Supercritical Fluid Extraction
Supercritical fluid extraction (SFE) is currently being investigated as a possible technique in the production of high quality mesophase pitch from coal tar and petroleum pitches. Mesophase pitch is used to make high technology products, such as carbon fibre. The conventional production of mesophase pitch initially involves the removal of low molecular weight species from coal tar and petroleum...
متن کاملPitch of synthetic sung vowels
Experiments a r e reported in which ~xus ica l ly trained subjects ~ i a t c h the pitch of zl. stimulus tone with a var iablc response tone, both tones being synthesis of a sung vo\vel. The effects on pitch and pitch perception ac curacy of vibratos of different kinds and tile ' singing formant' a r e examined. The resul t s appear to show that the pitch corresponds to the average fundamental ...
متن کاملSimulation of Flow–induced Texture Formation in Mesophase Pitch
Mesophase pitches are multicomponent discotic nematic liquid crystals (DNLCs), whose characteristic molecular weight is intermediate between low molar mass and polymeric nematic liquid crystals. The distinguishing features of the mechanical behavior can be summarized by stating that LC materials exhibit anisotropic, non-linear, viscoelastic behaviour quite distinct from Newtonian viscous materi...
