Novel hydrothermal carbonization of cellulose catalyzed by montmorillonite to produce kerogen-like hydrochar

open access: yes, 2014
The conversion of cellulose to petroleum-like fuel is a very challenging yet attractive route to developing biomass-to-fuel technology. Many attempts have been made in liquefaction, pyrolysis and gasification of cellulose to produce fuels or intermediate

Assessment of the hydrocarbon potential of the Bering Sea

open access: yesИзвестия высших учебных заведений: Геология и разведка, 2021
Background. The issues of hydrocarbon (HC) forecasting and prospecting on sea shelves remain relevant. In this paper, an experience of assessing the hydrocarbon potential of the Bering Sea using the method of basin modelling is demonstrated.Aim.

Raman Line Scan Analyses and a New Hypothesis for the Formation of Anatase‐Hosting Microbialites: Study of the Stromatolites From Saint‐Jean‐de‐la‐Rivière, Cotentin, France

open access: yesJournal of Raman Spectroscopy, EarlyView.
Micrometer analysis of millimeter lines of Raman spectra concludes in the association of anatase and graphitized organic matter (graphogen). The photosynthetic microorganisms at the origin of the microbialites produce O2, which is transformed by TiO2 into reactive species that, in turn, decompose the organic matter of the microorganisms. ABSTRACT Raman

Cretaceous-Tertiary boundary deposits in Denmark: A diachroneity [PDF]

open access: yesJournal of the Serbian Chemical Society, 2004
The lateral distribution of predominantly terrestrial kerogen or humics enriched with copper(II) porphyrins (Cu-P) across the Danish marine basin implies that the alleged Cretaceous-Tertiary (KT) boundary deposits in western Denmark (at the Nye Kløv ...
