“…Hydrofining is the technology used in refineries to upgrade oils with high impurities (Martínez and Ancheyta 2014). Sulfur, which is omnipresent in crude oil, is one of the main sources of particulates or soot emissions (Đukanović et al 2013), as well as sulfur dioxide, a gaseous pollutant commonly associated with acid rain (Paez et al 2015). In the hydrofining process, sulfur is removed from petroleum products in the form of hydrogen sulfide gas, which is then reacted with a base such as lime or lime stone to neutralize and stabilize the acidic compound to calcium sulfide.…”

“…Therefore, this has demanded the refineries to maximize the production yield of ultralow sulfur diesel fuel (Đukanović et al 2013). As for the gasoline, a review was made by Paez et al (2015) based on TIER 3 of Transportation Impact Environmental Review of the US Environmental Protection Agency. TIER 3 establishes new standards in emissions cutting from light-duty vehicles, expecting to reduce sulfur content of gasoline from 80-30 ppm currently to 10 ppm.…”

AbstractThe statistical information on the share of hydrogen sector-wise consumption indicates that 95% of the total consumption is utilized in ammonia synthesis, petroleum refining processes and methanol production. We discuss how hydrogen is used in these processes and in several smaller-scale manufacturing industries. We also present the trend of hydrogen used as fuel, and as an energy carrier in fuel cells for generating electricity, powering hydrogen vehicles, as well as in aerospace applications. Natural gas caters for approximately half of the total hydrogen production resources. Therefore, the scope is emphasized on relatively recent developments in research activities related to the conventional catalytic hydrocarbon processing technologies for the production of hydrogen derived from natural gas (methane), which are steam methane reforming, partial oxidation of methane and autothermal reforming. Hydrocarbon decomposition is included due to its potential to be industrialized in the future, and its benefits of producing clean hydrogen without emissions of greenhouse gases and generating carbon nanofibers or nanotubes as by-products that have the potential in various emerging applications. Attention is given to the efforts toward achieving hydrocarbon conversion improvements, energy savings through thermally efficient operation and reduced operational costs through minimization or elimination of coke formation in the catalytic processes.

“…Despite the impressive progress in the synthesis and catalytic application of sulfonated phosphines in the last decade, a significant number of novel applications have been developed recently. Thus, sulfonated phoshines are extensively used in hydroformylation [9][10][11][12][13], Suzuki-Miyaura coupling [14,15], hydrogenation of unsaturated esters [16], hydrogenation of levulinic acid to γ-valerolactone in aqueous media [17,18], catalytic hydrogenation of bicarbonate [19], hydrogenation of aldehydes [20] or heteroaromatic compounds [21]. A challenging application of transition metal catalysts modified by water-soluble phosphines is the hydrogenation of aromatic hydrocarbons under biphasic conditions.…”

Sulfonated Phosphine Ligands in the Ruthenium Catalyzed Biphasic Hydrogenation of Unsaturated Hydrocarbons

The hydrogenation of monocyclic aromatic hydrocarbons by ruthenium catalysts has been investigated in the presence of sulfonated monophosphine ligands with different stereoelectronic properties under biphasic conditions. The effects of (i) the number of sulfonate groups, (ii) the steric demand of the ligand and (iii) the σ-donor ability of the phosphorus atom have been investigated in the catalytic reactions. The TEM analysis of the catalytically active systems revealed that in situ formed soluble ruthenium nanoparticles (RuNPs) are responsible for the catalytic turnover. The Ru/sulfonated phosphine system with the properly tuned ligand exhibited high activity (8800 h −1) and selectivity in the hydrogenation of benzene to cyclohexane. Furthermore, the aqueous phase containing RuNPs could be recycled four times without a considerable loss of activity.
