Abstract

The characterization and pyrolysis behavior of a set of pitches prepared from anthracene oil have been described. The pitches were obtained from four successive cycles of a sequential process that begins with blowing air through the heated anthracene oil, to bring about recombination reactions. Reaction products are distilled to give a pitch residue and a lighter fraction. Thermal treatment/distillation cycles of this reaction product yield a pitch and a distillate fraction (unreacted anthracene oil) during each subsequent stage. Products obtained during the process have been characterized by elemental analysis, Fourier transform infrared (FTIR) and ultraviolet (UV)-fluorescence spectroscopy, and size-exclusion chromatography (SEC). The pyrolytic behavior of the anthracene oil derivatives was examined using a thermogravimetric balance. Thermal treatment of the anthracene oil and its (distilled) reaction products at 440-460{degree}C under 5 bar pressure leads to a partially anisotropic pitch with the formation of a liquid crystal phase (mesophase). The formation and evolution of these mesophases were analyzed by optical microscopy. 25 refs., 9 figs., 3 tabs.

Mesophase from anthracene oil-based pitches

Journal Article Alvarez, P; Sutil, J; Santamaria, R; ... - Energy and Fuels

This work deals with the preparation of the mesophase from two pitch-like materials obtained from anthracene oil by oxidative thermal condensation (AOP-1) and the subsequent thermal treatment and distillation of AOP-1 (AOP-2). The mesophase was obtained by the controlled pyrolysis (440-470{degree}C and different periods of residence times) and subsequent sedimentation of the samples. In the case of the pitch prepared by oxidative thermal condensation, a dynamic pressure of 5 bar was applied during the pyrolysis. The pressure was a critical parameter, and its influence was also investigated. The results show that AOP-1 requires higher temperatures and/or residence times to developmore »« less

Effect of secondary gas-phase reactions (SGR) in pyrolysis of carbon feedstocks for anisotropic carbon materials production – 3: Modifying non-coking coal tar through co-pyrolysis of coal with linear low-density polyethylene and high-impact polystyrene

Journal Article Malzahn, Joshua; Eddings, Eric - Journal of Analytical and Applied Pyrolysis

Herein, this work focuses on co-pyrolysis experiments of Utah Sufco coal with linear low-density polyethylene (LLDPE) and high-impact polystyrene (HIPS). These two plastic types have differing pyrolysis chemistries and have different hydrogen transfer behavior. Similar to earlier work in this series of papers, controlled secondary gas-phase reactions during pyrolysis were used to induce cracking and condensation reactions among the pyrolytic tar species. Co-pyrolysis tests were performed with feed plastic percentages ranging from 10-20 wt% and pyrolysis SGR temperatures ranging from 800-900°C. Analyses of the intermediate tar products showed that oxygen contents and aromaticity were substantially different, depending on the plastic,more »« less

Green Needle Coke Production from Pyrolysis Biocrude toward Bio-based Anode Material Manufacture: Biochar Fines Addition Effect as “Physical Template” on the Crystalline Order

Journal Article Reyes Molina, Eliezer; Vook, Trevor; Sagues, William; ... - ACS Sustainable Chemistry & Engineering

Here, a new method for producing green needle coke (GNC) is developed by replacing the “heavy fraction” of petroleum pitch delayed coking with fast pyrolysis biocrude. A series of alternative biocrude distillation, carbonization, and calcination conditions were investigated to determine the influence of these processing parameters onto the crystalline structure of the resulting graphitized material. For the first time, the addition of biochar fines was found to serve as a “physical template” to increase the graphitic nature of the final product. During the initial biocrude carbonization (350–450 °C), volatile compounds are released, and aromatics in pyrolysis biocrude experience condensation, resultingmore »« less

Thermochemical transformations of anthracene oil

Journal Article Belkina, T; Privalov, V; Stepanenko, M - Coke Chem. USSR (Engl. Transl.); (United States)

The basic technological step in electrode pitch production is the thermal processing of the original pitch, combined in some cases with air treatment. The thermal process of electrode pitch production is outstandingly simple and economical, but offers little scope for regulating the product quality. When the coal tar regulating the product quality has been highly pyrolyzed, it becomes difficult to produce a medium electrode pitch in conformity with GOST 10200-73 as regards its content of substances insoluble in quinoline (..cap alpha../sub 1/-fraction). It is particularly difficult to make ptich with a softening point of 85 to 90/sup 0/C from highlymore »« less
Pyrolysis Pathways of Sulfonated Polyethylene, an Alternative Carbon Fiber Precursor

Journal Article Younker, Jarod; Saito, Tomonori; Hunt, Marcus; ... - Journal of the American Chemical Society

Sulfonated polyethylene is an emerging precursor for the production of carbon fibers. Pyrolysis of sulfonated polyethylene was characterized by thermogravimetric analysis (TGA). n-heptane-4-sulfonic acid (H4S) was selected as a model compound for the study of sulfonated polyethylene. Density functional theory and conventional transition state theory were used to determine the rate constants of pyrolysis for H4S from 300-1000 K. Multiple reaction channels from two different mechanisms were explored: 1) internal five-centered elimination (Ei 5) and 2) radical chain reaction. The pyrolysis of H4S was simulated with kinetic Monte Carlo (kMC) to obtain TGA plots that compared favorably to experiment. Wemore »« less
