“…The choice of the method for judging the cracking degree of crude oil is mainly affected by the regional thermal background and the degree of thermal evolution of organic matter (Chen et al, 2016). Under low thermal evolution conditions, biomarker parameters including hopane (Ts/(Ts + Tm)) (Zhang et al, 2016;Corma et al, 2018), rearranged sterane (C 29 Ts/ (C 29 Ts + C 29 H)) (Peters and Walters, 2005), methyl phenanthrene ratio (MPR) (Radke et al 1982) or gas-oil ratios (GOR) (Claypool and Mancini, 1989) can quantitatively evaluate crude oil maturity and cracking rate. Moreover, the stable diamondoids component in crude oil can indicate the degree of cracking of crude oil during high thermal evolution stage (Dahl et al, 1999).…”

With the deepening of oil and gas exploration, the importance of depth is increasingly highlighted. The risk of preservation of storage space in deep reservoirs is greater than that in shallow and medium layers. Deep layers mean older strata, more complex structural evolution and more complex hydrocarbon accumulation processes, and even adjustment and transformation of oil and gas reservoirs. This paper systematically investigates the current status and research progress of deep oil and gas exploration around the world and looks forward to the future research focus of deep oil and gas. In the deep, especially the ultra-deep layers, carbonate reservoirs play a more important role than clastic rocks. Karst, fault•karst and dolomite reservoirs are the main types of deep and ultra-deep reservoirs. The common feature of most deep large and medium-sized oil and gas reservoirs is that they formed in the early with shallow depth. Fault activity and evolution of trap highs are the main ways to cause physical adjustment of oil and gas reservoirs. Crude oil cracking and thermochemical sulfate reduction (TSR) are the main chemical modification effects in the reservoir. Large-scale high-quality dolomite reservoirs is the main direction of deep oil and gas exploration. Accurate identification of oil and gas charging, adjustment and reformation processes is the key to understanding deep oil and gas distribution. High-precision detection technology and high-precision dating technology are an important guarantee for deep oil and gas research.

“…In this regard, the reduction of the sulphur contents of diesel and gasoline in the advancing years is expected to be nearing 10 and 50 ppm sequentially. A small degree of sulphur in transportation fuels will not only at-once better the standard of air by decreasing SO x emissions, but will also indirectly reduce the NO x and hydrocarbon emissions by permitting the better work of automotive catalytic converters [47,48]. As a result of the enacting demand for a radical decrease in the sulphur content of automotive fuels (say 30 ppm in gasoline and 15 ppm in diesel) that was fully enforced in 2009, much attention has been given to the deep desulphurization of transportation fuels in the research community globally.…”

Sustainable development and enhancement of cracking processes using metallic composites

et al. 2021

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.

“…3 On the other hand, the demand for traditionally oil-manufactured base chemicals is expected to keep rising in the foreseeable future. 4,5 The mismatch between current oil refining schemes and future demand for oilbased products is stirring intense research into the development of technologies that maximize the production of chemicals over that of fuels, giving rise to multi-billion investments in different oil-to-chemicals (OTC) projects (some of these technologies have been summarized in the Supporting Information). At present, the main approach in OTC is to combine technologically mature technologies (i.e.…”

One-step conversion of crude oil to light olefins using a multi-zone reactor

et al. 2021

View full text Add to dashboard Cite

With demand for gasoline and diesel expected to decline in the near future, crude-tochemicals technologies have the potential to become the most important processes in the petrochemical industry. This trend has triggered intense research into the optimization of current refining processes to maximize the production of light olefins and aromatics at the expense of fuels. Although attractive, this approach has shown certain limitations and calls for disruptive processes able to directly transform crude to chemicals in a more efficient and environmentally friendly way. Here we propose a new reactor concept consisting of a multi-zone fluidized bed (MZFB) along with a new catalyst formulation able to perform several refining steps in one single reactor vessel. The MZFB configuration allows for in situ catalyst stripping and regeneration, while the incorporation of silicon carbide during catalyst shaping via spray drying confers this new catalyst formulation with improved physical, mechanical and heat transport properties. As a result, we demonstrate that, using this reactor-catalyst combination, it is possible to achieve stable direct
