“…Therefore, the design and synthesis of applicable catalytic materials is the key to improve the performance of hydrodesulfurization. Over the years, scholars have developed of a wide range of the hydrodesulfurization catalysts, such as transition metal sulfides [2], carbide [3,4], nitrides [5,6], precious metals [7,8], and phosphides [1]. In particular, transition metal phosphides exhibit a catalytic ability similar to precious metals in the hydrodesulfurization reaction, and have excellent activity and sulfur resistance.…”

“…The methyl groups suppressed the direct desulphurization of 4,6-DMDBT, but significantly promoted the hydrogenation of 4,6-DMDBT and the dehydrogenation of 1,2,3,4-tetrahydro-4,6-dimethyldibenzothiophene (TH-4,6-DMDBT) and 1,2,3,4,4a,9b-hexahydro-4,6-dimethyldibenzothiophene, but decreased the rate of hydrogenation of TH-4,6-DMDBT ( Fig. 3) [70].…”

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.

“…Omówione problemy powodują konieczność poszukiwania nowych materiałów katalitycznych, nośnika i fazy aktywnej, które w przyszłości mogłyby się stać materiałami wyjściowymi do otrzymania i syntezy nowych, bardziej aktywnych katalizatorów hydrorafinacji. Istnieje duża grupa materiałów będących potencjalnymi niesiarczkowymi katalizatorami głębokiej hydrorafinacji, do której należą: węgliki [9,19,21,22,[32][33][34], fosforki [8,26,29,37] oraz ostatnio również borki metali przejściowych [17,18]. Materiały te to tzw.…”

Chemia i katalizatory procesu głębokiego hydroodsiarczania W artykule przedstawiono zagadnienia związane ze zrozumieniem mechanizmu katalitycznego procesu głębokiego hydroodsiarczania (HDS). Omówiono rodzaje związków siarki występujących w surowcach naftowych oraz ich reaktywność w aspekcie drugiego stopnia hydrorafinacji. Opisano typy katalizatorów procesu HDS oraz przedstawiono zagadnienia związane z wykorzystaniem nowych katalizatorów (niesiarczkowych) mających potencjalne zastosowanie w drugim (głębokim) stopniu hydrorafinacji.Słowa kluczowe: hydroodsiarczanie (HDS), hydrorafinacja, reaktywność związków siarki, karbazol, dibenzotiofen (DBT), 4,6-dimetylodibenzotiofen (4,6-DMDBT). Chemistry and catalysts of deep hydrodesulfurization processThe paper presents issues related to the understanding of the catalytic mechanism of the deep hydrodesulphurization process (HDS). The types of sulfur compounds present in petroleum products and their reactivity in terms of the second degree of hydrotreatment are discussed. The types of catalysts for the HDS process were described and the issues related to the use of new (non-sulfide) catalysts which have potential application in the second (deep) hydrotreatment are presented.
