In the present era, many Petrochemical Industries (PIs) are driven energetically due to IIoT (Industrial Internet of Things) Communication Networks/Architectural Layers (CNs/ALs), abbreviated as PI4.0-CNs/ALs. PI4.0 fruitfully participated to achieve the Circular Economy (CE) by speeding the reutilization, recovery, and recycling of scrap materials by minimizing cost, unproductive operations, energy consumption, emission of flue gases, etc. Recently, it has been ascertained that the identification and measurement of Research Trends (RTs) of CNs-ALs help the PI4.0 to build the future CE. In addressing the said research challenge, the objective of this research dossier is turned towards inculcating into future PI4.0 researchers the RTs of CNs/ALs of PI4.0, so that the researches can be organized over the very weak and moderately performing CNs-ALs to hike the future CE. To materialize the RTs of PI4-CNs/ALs, the authors conducted the Systematic Literature Survey (SLS) focusing on PI4.0-CNs/ALs, i.e., Internet of Things (IoTs), Cyber Physical System (CPS), Virtual Reality (VR), Integration (I), Data Optimization (DO), Enterprise Resource Planning (ERP), Plant Control (PC), Data and Analytics (DA), Network (N), and Information and Data Management (IDM). The authors searched three hundred two research documents, wherein two hundred seventy-five research manuscripts qualified as RQ2. Next, the authors collected the DOIs/URLs corresponding to each CN-AL and explored the Sum of Digit Scoring System (SDSS) to summarize the DOIs/URLs of PI4.0-CNs/ALs. The RTs of DO have been determined as excellent and stronger over 2007-2017 than residue CNs/ALs. Eventually, the authors advised scholars to focus on the research areas of very weak and moderately weak performing CNs/ALs in order to attain future CE.

“…Coke plays a crucial part in the ISC process and is considered the fuel for the movement of the combustion front. , Usually, coke forms ahead of the combustion front and can help maintain stability. Thus, the two main characteristics of coke, quantity and activity, determine the success of the ISC technique.…”

“…For thermal pyrolysis coke, only an external heat source is necessary. 8,18 In recent years, thermal analysis has been applied as the main investigation method for the properties of crude oil under ISC conditions. ISC provides an elevated temperature environment to simulate a combustion front, so we can measure the weight loss and activation energy of the experimental sample.…”

In order to understand the mechanism of in situ combustion, many studies have investigated the characteristics and properties of oxidized coke and pyrolyzed coke. However, in earlier research, the influence of light hydrocarbon and other compounds always led to a calculation error in the activation energy. In the work described here, we produced and separated oxidized coke and pyrolyzed coke, respectively, first to eliminate the influence of impurity and, second, to examine their properties by means of the TG-DSC equipment. The kinetic parameters were calculated by the Ozawa–Flynn–Wall model. The results showed that the crude oil achieved two major mass losses in the 300–400 and 500–600 °C temperature ranges, while the oxidized coke and the pyrolyzed coke released more heat than crude oil in the same conditions. At 300 and 350 °C, the high temperature can cause the thermal pyrolysis of the crude oil because the generation of coke requires more energy. These temperature levels cannot trigger the generation of coke and thus the pyrolyzed products stayed in one phase. At 400 °C, the pyrolyzed product cracked into two products: light oil and coke. The generated coke could only achieve major mass loss over 500 °C, releasing more heat than both oxidized oil and crude oil. According to the Ozawa–Flynn–Wall model, the crude oil achieved higher instantaneous activation energy at each conversion rate compared to results for oxidized coke and pyrolyzed coke. With the increase in conversion rate, the activation energy of oxidized coke rose while that of pyrolyzed coke decreased slightly.
