Multistage alkaline permanganate degradation of a type-III kerogen

, 1985
In order to obtain evidence on the relationship between kerogen structural types and the quantity and nature of their oxidation products, the products of a multistage (13 step) alkaline permanganate degradation of type-III kerogen from a sample of the ...

Pyrolysis Kinetics of Lacustrine Shales from the Yanchang Formation: Revealing the Role of Kerogen Type in Shaping Hydrocarbon Generation and Expulsion Pattern

Geosciences
The Yanchang Formation in the Ordos Basin is a key target for continental shale oil exploration in China. Due to its complex geological background and diversified organic inputs, the hydrocarbon generation and accumulation in the lacustrine basin remain ...

Controlling factors of organic matter enrichment in continental shale: A case study of the Jurassic Da’anzhai member in the Sichuan Basin

Frontiers in Earth Science, 2022
The continental lake basin is a favorable accumulation area of shale oil and gas; however, the organic matter enrichment regularity in continental lake facies is still controversial, which hinders the exploration of continental shale oil and gas in the ...

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

, 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

XPS direct analysis on shale rocks: Correlation with kerogen type and maturity

, 2019
A method to study kerogen type and maturity of organic matter in source rocks using XPS was developed. Samples from three Argentinian shale rocks containing different kerogen types were analyzed by XPS directly, without kerogen isolation.

Photochemical effects of Mars‐like UV irradiation on carboxylic acids in carbonaceous chondrites and expectations for abiotic background organics on Mars

Meteoritics &Planetary Science, EarlyView.
Abstract In the search for life on Mars, understanding the origin of preserved organics is critical. Expected sources include exogenous delivery, endogenous synthesis, and potentially life. Environmental processing by ultraviolet (UV) irradiation can alter these organics, obscuring hallmarks of their origin. To deconvolve these effects, we conducted an

Gaseous products of organic matter thermal decomposition depending on the type of kerogen [PDF]

The aim of the research was to ascertain the possibility of determining the type of kerogen based on gaseous products of pyrolysis of rocks containing organic matter. The relationship between the type of kerogen and the obtained gas products is important

Coupled plagioclase dissolution and K‐feldspar overgrowth precipitation preserve anomalously high permeability in deeply buried sandstones

Sedimentology, EarlyView.
ABSTRACT This study investigated the formation mechanism responsible for anomalously high permeability (AHP) observed in the Eocene sandstones at depths from 3824 to 3832 m in the Huizhou Sag, Pearl River Mouth Basin, China, using helium porosity and permeability measurements, thin section, scanning electron microscopy, electron probe X‐ray ...
