Alternate use of heavy hydrotreatment and visbreaker naphthas by incorporation into diesel

open access: yesFuel Processing Technology, 2007
Abstract In order to provide a solution for refineries having limited catalytic reforming capacity, a process scheme for incorporating most of the low octane heavy hydrotreatment and visbreaker naphthas into diesel is presented in this paper. This scheme involves blending the visbreaker naphtha with the feed to the diesel hydrotreatment units ...

Learning hydrocracking reaction dynamics via neural ODEs: A data‐driven, gradient‐interpretable lumped modelling framework

open access: yesThe Canadian Journal of Chemical Engineering, Volume 104, Issue 3, Page 1372-1386, March 2026.
This work demonstrates the application of neural ordinary differential equations (neural ODEs) for learning hydrocracking reaction kinetics directly from data, achieving robust predictions under noise and sparsity while preserving mechanistic interpretability through gradient‐based analysis of temperature‐ and concentration‐dependent reaction rates ...

Laboratory study of cyclic liquid solvent injection process for heavy oil recovery through computed tomography

open access: yesDyna, 2019
The cyclic solvents injection has been considered for years as an improved non-thermal enhanced oil recovery method for the recovery of heavy oil, which includes three stages: injection, soaking, and production.

Characterization of naphtha produced from coprocessing coal-heavy oil

open access: yes, 1986
Capillary gas chromatography proved useful for characterizing naphtha produced from coprocessing coal and heavy oil at various conditions. Increasing the coal concentration in the feedstock resulted in higher contents of phenols, indane and cyclohexanes in the naphtha product.

Meta‐Analysis of Industry Incident Reports: Identifying Gaps in Climate‐Related Safety Risks

open access: yesSafety Science and Technology, Volume 1, Issue 1, March 2026.
Climate‐related hazards like floods, storms, and heatwaves are increasing, raising concerns for industrial safety. When such events trigger technological failures (NATECH incidents), consequences can be severe, particularly in chemical and energy sectors. A PRISMA and bowtie‐based meta‐analysis of 50 climate‐linked incidents from the US Chemical Safety
