Screen-printed carbon electrodes modified with cobalt phthalocyanine for selective sulfur detection in cosmetic products

Cobalt phthalocyanine (CoPc) films were deposited on the surface of a screen-printed carbon electrode using a simple drop coating method. The cyclic voltammogram of the resulting CoPc modified screen-printed electrode (CoPc/SPE) prepared under optimum conditions shows a well-behaved redox couple due to the (Co(I)/Co(II)) system. The CoPc/SPE surface demonstrates excellent electrochemical activity towards the oxidation of sulfur in a 0.01 mol·L(-1) NaOH. A linear calibration curve with the detection limit (D(L), S/N = 3) of 0.325 mg·L(-1) was achieved by CoPc/SPE coupled with flow injection analysis of the sulfur concentration ranging from 4 to 1120 mg·L(-1). The precision of the system response was evaluated (3.60% and 3.52% RSD for 12 repeated injections), in the range of 64 and 480 mg·L(-1) sulfur. The applicability of the method was successfully demonstrated in a real sample analysis of sulfur in anti-acne creams, and good recovery was obtained. The CoPc/SPE displayed several advantages in sulfur determination including easy fabrication, high stability, and low cost.     

Reformulation of FCC gasoline

FCC gasoline obtained from an Indian refinery was analyzed for its quality improvement through catalytic processes. The analysis indicated the presence of high amount of sulfur, olefin and iso-paraffins in the feed that are not suitable for processing through the hydro treatment or hydro-isomerization. Detailed studies indicated that majority of iso-paraffinic and olefinic compounds in the feed boil below 60 °C. The entire range of gasoline is fractionated into light fraction (IBP-60 °C) and heavy fraction (60 °C-FBP). Heavy hydrocarbon fraction exhibited more aromatics and sulfur with comparatively low olefins and iso-paraffins. HDS followed by hydro-isomerization of the heavier fraction resulted in the formation of C₆-C₉ iso-paraffins through the saturation of olefins and aromatics. Overall, the processed FCC gasoline exhibited more iso-paraffins with low olefins, low aromatics and sulfur, without any loss in octane number.     

Base‐free catalytic aerobic oxidation of mercaptans for gasoline sweetening over HTLcs‐derived CuZnAl catalyst

An aerobic oxidative removal of mercaptans from gasoline in the absence of liquid base has been demonstrated for gasoline sweetening over CuZnAl catalyst. This process could proceed at large WHSV of gasoline (50–70 h^?1) with >95% mercaptan conversion at 150°C (or 300°C) using an O₂/S molar ratio of 20–40. At 150°C, dimerization of mercaptans occurred dominantly to form their disulfides. At 300°C, deep oxidation of the mercaptans to SO₂ was the dominant process in the first tens of hours, but it decreased then with prolonged time on stream and meanwhile the dimerization increased. The spent catalyst could be restored to its fresh activity level only through a calcination treatment in air. This process was also demonstrated to be effective and efficient for sweetening of a real cracking gasoline. © 2009 American Institute of Chemical Engineers AIChE J, 2009

Extractive desulfurisation of gasoline with tetrabutyl ammonium chloride-based deep eutectic solvents

In this study, three tetrabutyl ammonium chloride (TBAC)-based deep eutectic solvents (DESs) were synthesised and used for desulfurising model and real gasolines. Extraction efficiencies of different DESs followed the order of TBAC/ethylene glycol > TBAC/glycerol > TBAC/malonic acid. After five extraction cycles, the extraction efficiencies of TBAC/ethylene glycol, TBAC/glycerol and TBAC/malonic acid reached 99.5, 99.3 and 99.2%, respectively. Additionally, the structures of original and recycled DESs were analysed and the results showed that DESs maintained their original structures after regeneration. Finally, the desulfurisation performance of DESs for real gasoline was also investigated. This work will provide new green extractants for gasoline desulfurisation.
