The structure of the centrosymmetric title compound, C8H10O2, originally determined by Goodwin et al. [Acta Cryst.(1950), 3, 279–284], has been redetermined to modern standards of precision to aid in its use as a model compound for 13C chemical-shi

Recent detailed chemical structure analyses of three demineralized kerogens from Green River oil shale samples were used to generate input parameters for the chemical percolation devolatilization (CPD) model. This model uses a lattice network to desc

This paper is Part II of a study of the chemical structural components of the organic matter of oil shale in the Green River formation. Three sections of a well-characterized oil shale core from the Utah Green River formation were demineralized, and

This paper is the first of two associated papers describing the structural details of three sections of an oil shale core taken at the Skyline 16 mine in the Utah Uinta Basin. Bitumen was extracted from the shale using methanol/dichloromethane. Kerog

Volatile products from an oil shale from the Colorado Green River formation were studied by several methods. The oil shale was demineralized, and the resulting kerogen was also chemically analyzed. Both the oil shale and the demineralized kerogen wer

The purpose of the research reported here is to explore how minor coal composition changes can affect oxy-coal flame ignition. Whereas previous work focused on the stability of coaxial turbulent diffusion flames for a single coal, we explore here how

Three-dimensional (3D) structural models of the Green River kerogen based on the two-dimensional (2D) structure proposed by Siskin were generated using a combination of ab initio and molecular mechanics calculations. Several initial monomer conformat

This paper presents calculations of 13C solid state NMR (SSNMR) spectra of model asphaltenes. The overall goal of this work is to assess how valuable 13C SSNMR studies of asphaltenes can be in guiding the development of representative 3D (three-dimen

Ferrihydrites (FHYDs) with the general formula of FeOOH·nH2O are naturally occurring oxyhydroxide minerals found in environments varying from river beds, lakes, and marshes to even living organisms. Here, we report the synthesis of a new kind of syn

Mixed 4.5% iron oxide−95.5% cerium oxide aerogels doped with 1% and 2% palladium (Pd) by weight have been synthesized, and their activities for the catalysis of water−gas shift (WGS) reaction have been determined. The aerogels were synthesized us
