BACKGROUND Pyrolysis of slaughterhouse waste could promote more sustainable phosphorus (P) usage through the development of alternative P fertilizers. This study investigated how pyrolysis temperature (220, 350, 550 and 750 °C), rendering before pyrolysis, and wood or corn biomass additions affect P chemistry in bone char, plant availability, and its potential as P fertilizer. RESULTS Linear ...

Characterizing the origin of natural fractures in organic-rich fine-grained deposits is key to constraining permeability evolution these potential source rocks and tight reservoirs, as well assess hydraulic connectivity fluid systems which they develop. Differently oriented calcite-filled (i.e. veins), hosted by mudrocks Lower-Middle Triassic Montney-Doig unconventional resource play (Western C...

In this paper, we report the pyrolysis and formation of magnetic minerals in three source rock samples from the Wessex Basin in Dorset, southern England. The experimental conditions in the laboratory recreated the catagenesis environment of oil source rocks. Magnetic analysis of both the heated and the unheated samples at room temperature and at very low-temperatures (5 K), coupled with transmi...

This study investigates the role of zooclasts in bulk organic matter composition, kerogen type, and hydrocarbon generation potential lower Paleozoic marine Alum shale Baltoscandia, northwestern Europe. The results show that graptolite periderm is composed non-granular cuticles granular filling. cuticle non-fluorescing has a well-polishing measurable surface, while fraction semi-translucent brow...

Oil shales are developed in the Shale Member of Middle Jurassic Shimengou Formation Qaidam Basin, China. The oil can be classified into three quality groups (low-, medium-, and high-quality shales) through a comprehensive analysis protocol that includes Rock-Eval pyrolysis, total organic carbon (TOC) content, proximate analysis, gas chromatography-mass spectrometry (GC-MS), X-ray diffraction (X...

Ditch samples from AP-4, ER-51 and UK-2 offshore Niger Delta were subjected to biostratigraphic organic geochemical analyses which entail foraminiferal, palynological, Spore Colour Index (SCI), Rock-Eval Pyrolysis Fourier Transform Infrared Spectroscopy (FTIR) analyses. The results have established N19 N17; N17, N16 N15; N9 N8 biozones; P600 P700 palynological zones. dominance of palynomaceral ...

In situ shale or kerogen oil production is a promising approach to developing vast resources and increasing world energy demand. this study, cyclic subcritical water injection in was investigated laboratory conditions as method for retorting. Fifteen non-extracted samples from Bazhenov Formation Russia (98 °C 23.5 MPa reservoir conditions) were hydrothermally treated at 350 25 semi-open system ...

Abstract In this study, we combined the geochemical characteristics based on Rock-Eval pyrolysis and gas chromatography – mass spectrometry (GC–MS) results with facies analysis. These surveys were conducted within grey to black claystones/mudstones intervals of Podil’tsi Kokhanivka formations, related Pliensbachian Toarcian–Bathonian ages, respectively. The revealed that Formation contains mixe...
