Studies on thermal cracking behavior of residual feedstocks in a batch reactor

Co-pyrolysis of heavy oil and low density polyethylene in the presence of supercritical water: The suppression of coke formation

“…Comparing the results presented in Fig. 1 and Table 2 with literature reports, one may find that the pyrolysis of heavy oil in the presence of SCW basically has the same product distribution with that in the absence of SCW [17,18]. In fact, most of the relevant researches considered SCW as an inert reaction medium for the pyrolysis of heavy oil in SCW, a process still determined by the free radical mechanism [19,20].…”

Kinetic analysis using thermogravimetric analysis for nonisothermal pyrolysis of vacuum residue

“…Many reports show that first-order reaction can be acceptably applied to pyrolysis, and therefore, the pyrolysis of VR in this study is assumed to follow a first-order reaction, according to the following equation [7,[20][21][22][23][24][25].…”

“…Therefore, the production of VR will increase significantly as more unconventional oil is treated in oil refineries [5,6]. However, the use of VR is limited because of problems such as its low economic value, high viscosity and density, and high contents of nitrogen, sulfur, and heavy metals [7,8].…”

Reaction pathway analysis in thermal cracking of waste cooking oil to hydrocarbons based on monomolecular lumped kinetics

“…The kinetic modeling of refinery processes such as thermal cracking [31][32][33][34][35][36][37], catalytic cracking [38][39][40][41][42][43][44] and hydrocracking [45][46][47][48][49][50][51][52] was well established. Discrete lumping approach [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49]52] was successfully applied for modeling of aforementioned processes. Thermal cracking of residual feedstock was investigated in a batch reactor and observed that the reactions follow first order kinetics [31].…”

Thermal cracking of residual feedstock was investigated in a batch reactor and observed that the reactions follow first order kinetics [31]. A kinetic model for thermal cracking reactions in bitumen reservoirs was developed by Jia et al [32].…”
