“…One of them is the chemical oxidation of hydrogen sulfide and thiols in an organic medium using one-electron oxidants, sterically hindered o-benzoquinones (9). This variant leaded to the production of elemental sulfur and alkyldisulfides of a symmetric structure, which are separated for the purposeful use of alkyl disulfides and the attraction of sulfur in the three-component organic synthesis (11).…”

“…For example, in the process of atmospheric distillation of high-sulfur gas condensate, the residue of atmospheric distillation (straight-run fuel oil) is obtained, containing the sulfur waste hydrogen sulfide and thiols, which are used as the main components of commercial fuel oil for heating. Among the known methods, the most widely used methods for reducing the content of sulfurous waste in fuel oil are the following: blowing off with inert or hydrocarbon gases, the use of chemical absorbers, or ozonolysis [11,12]. Chemical reagents, which are used as various organic and inorganic compounds, are widely used to solve the problem of neutralizing hydrogen sulfide [13].…”

A logical-informational model of energy resource-efficient chemical technology for the utilization of hydrogen sulfide and low molecular alkanethiols, which are toxic and difficult to remove sulfur components of residual fuel (fuel oil), is proposed. Based on the IDEF1 methodology and existing knowledge about the technological processes of the demercaptanization of various hydrocarbon raw materials (oils, gas condensates), a scheme for the production of organic sulfur compounds from sulfur waste extracted from fuel oil has been modeled. For a sufficiently complete removal of hydrogen sulfide and low molecular weight alkanethiols, energy- and resource-saving stages of the technological process have been developed, which are implemented by ultrasonic and/or magnetic treatment of fuel oil. It is proposed to use the combined action of two alternative methods of processing fuel oil to increase the efficiency of cleaning fuel oil from sulfur components. For the first time, an approach has been developed to utilize unwanted sulfuric impurities contained in fuel oil by involving electric and microwave synthesis in green technological processes, to obtain practically useful organic sulfur compounds with biological activity. It is shown that the use of one-electron oxidant thiols and hydrogen sulfide in organic media leads to the synthesis of organic disulfides and elemental sulfur. Indirect (with the use of mediators) electrosynthesis contributes to the cyclic conduct of the technological process, an increase in efficiency and a decrease in energy consumption compared to the direct (on electrodes) initiation of sulfur components.

“…Similarly, polyunsaturated species should be <1% (m/m) in biodiesel . It has been suggested that sulfur-rich fuel contains diarylsulfides, thiophenes, alkyl arylsulfide, benzothiacyclic, dibenzothiacycanes, benzothiophenes, naphthothiophenes, which emit flue gas containing a high percentage of SO 2 as well as SO 3 that converts to very corrosive sulfurous acid . Thus, green biofuel may be considered as a possible solution to combat with the increasing CO 2 and the emission of other toxic gases in the atmosphere.…”

Metal-free catalysis is particularly challenging in the context of green and sustainable chemistry. High toxicity associated with the leaching of the metals from the catalysts has notorious environmental impact. To surmount such an effect, homogeneous organocatalysis can provide a green and alternative protocol. However, it suffers the drawbacks of low activity and selectivity, because of the neighboring effect of the solvent, and it is devoid of recyclability for sustainable operations. To address such issues, solid-supported heterogeneous organocatalysts are developed, and these have been attracting increasing interest over the years. Multifunctional porous organic materials are very demanding in catalysis, because of their robustness in the structure involving strong covalent bonds between organic building blocks. Furthermore, their high specific surface area, topological diversity, and finely dispersed catalytic sites in nanoscale could make these porous organic materials as excellent scaffold for several task-specific applications. Lightweight and high inherent porosity, as well as structural stability with tenability of the active functional groups, have reinforced their tremendous potential as solid organocatalyst. In this Perspective, we highlight the latest advancements in metal-free cross-linked amorphous porous organic polymers (POPs) and crystalline covalent organic frameworks (COFs), their design principle to incorporate catalytic sites for major applications such as biomass conversion, biofuel synthesis, asymmetric organocatalysis, and CO2 fixation reactions. Several renewable and sustainable catalytic transformations could be achieved via environmentally benign pathways through this alternative metal-free approach.

“…Andrienko et al [110] reported the study on the removal of sulphur-containing compounds from fuel oils using a naturally occurring iron oxyhydroxide. Studies have shown that water deferrization waste like iron oxyhydroxide could be used as catalysts for the removal of sulphur-containing compounds (SCC) present in fuel oil through the oxidative desulphurization process.…”

“…However, the maximum parameters of the oxidation process were obtained; each time, SCC was removed from the fuel oil in the oxidative desulphurization process [31,111]. During this process which consisted of successive stages, the degree of desulphurization obtained for the fuel oil was 92.3% as a result of the successive SCC removal from the fuel oil during the various stages of oxidation of SCC as well as the extraction of the oxidized SCC present in the fuel oil [110]. The removal of sulphur-containing compounds from the oil feedstock making use of iron oxyhydroxide as a catalyst through oxidative desulphurization could be in huge demand for industrial uses due to the high catalytic activity of this readily available low-cost catalyst in the oxidation processes.…”

Sustainable development and enhancement of cracking processes using metallic composites

Metallic composites represent a vital class of materials that has gained increased attention in crude oil processing as well as the production of biofuel from other sources in recent times. Several catalytic materials have been reported in the literature for catalytic cracking, particularly, of crude oil. This review seeks to provide a comprehensive overview of existing and emerging methods/technologies such as metal–organic frameworks (MOFs), metal–matrix composites (MMCs), and catalytic support materials, to bridge information gaps toward sustainable advancement in catalysis for petrochemical processes. There is an increase in industrial and environmental concern emanating from the sulphur levels of oils, hence the need to develop more efficient catalysts in the hydrotreatment (HDS and HDN) processes, and combating the challenge of catalyst poisoning and deactivation; in a bid to improving the overall quality of oils and sustainable use of catalyst. Structural improvement, high thermal stability, enhanced cracking potential, and environmental sustainability represent the various benefits accrued to the use of metallic composites as opposed to conventional catalysts employed in catalytic cracking processes.
