Adsorption Desulfurization of Liquid Fuel Using a Blend of Date Stones and Walnut Shells by Box–Behnken Design

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A specific microporous KOH/activated‐biochar (K/BC) was produced from a blend of date stones (DS) and walnut shells (WS) and used in the adsorptive desulfurization (ADS) of two types of model fuel DBT/n‐hexane (S‐hex), DBT/cyclohexane (S‐cyclohex).

Pollutants Transformation During the Regeneration Process of Fluid Catalytic Cracking Catalysts

Angewandte Chemie, Volume 137, Issue 52, December 22, 2025.
Fluid catalytic cracking is the main pollutant source in crude oil refineries due to spent catalyst regeneration. In this work, flue gas pollutants are monitored and coke deposits are identified. Operando and in situ spectroscopy are developed to explore coke species evolution, coupled with online gas infrared spectroscopy to detect pollutant formation.

Exploring the Mechanism of Biocatalyst Inhibition in Microbial Desulfurization [PDF]

, 2013
Microbial desulfurization, or biodesulfurization (BDS), of fuels is a promising technology because it can desulfurize compounds that are recalcitrant to the current standard technology in the oil industry. One of the obstacles to the commercialization of

Supercritical water deasphalting and desulphurization of heavy fuel oil with comprehensive molecular‐level analysis and techno‐economic analysis

The Canadian Journal of Chemical Engineering, EarlyView.
Supercritical water deasphalting. Abstract The removal of sulphur from heavy fuel oil (HFO) is essential to address environmental concerns and comply with the stringent regulations imposed by the International Maritime Organization (IMO) in 2020. Previously, the acceptable limit for sulphur was 3.5 wt.%, but it was recently changed to 0.5 wt.%.
