“…In various studies, these interactions resulted in non-linear changes in yields, unlike the linear changes in yields from the individual pyrolysis of FS. The interactions also increased the yield of oil and its H/C ratio, as observed by Chen et al [79], and the yield of gas while reducing that of solid residues [80,82,[84][85][86]. The synergetic effect of co-pyrolysis can depend on the blend ratio of BM:OS, as shown by Dai et al [84], who demonstrated a maximum synergy at 30 wt% blends of OS using microalgae and OS.…”

The use of biomass (BM) and oil shale (OS) blends for the production of cleaner and improved fuels and chemicals through co-pyrolysis has recently attracted attention. The potential benefits, synergetic effects, interactions and promotion and inhibition effects of co-pyrolysis of BM and OS are reviewed and analyzed in this article based on an overview of various recent studies of co-pyrolysis, including the experimental and operational parameters and the yield and composition of the products. The effects of co-pyrolysis on different feedstock blends are discussed to guide future research on BM and OS copyrolysis. The effects of different pyrolysis parameters that can improve the pyrolysis process and quality of products are also reviewed. These parameters include CO 2 and steam atmospheres, heating rate, reaction temperature and particle size. Overall, in most cases reviewed, co-pyrolysis can enhance the yields of bio-oils, producer gas and chars as well as improve their properties while reducing the environmental effects of fossil fuels.

“…As can be seen from Table 3 , activation energies in the conversion degree range of 0.2–0.8, reduced with co-pyrolysis. Reduction activation energy was reported during co-pyrolysis of biomass with plastic waste [ 36 , 37 , 38 , 39 ]. Co-pyrolysis resulted in a gradual decrease in average activation energy.…”

Continuous growth in energy demand and plastic waste production are two global emerging issues that require development of clean technologies for energy recovery and solid waste disposal. Co-pyrolysis is an effective thermochemical route for upgrading waste materials to produce energy and value added products. In this study, co-pyrolysis of sheep manure (SM) and recycled polyethylene terephthalate (PET) was studied for the first time in a thermogravimetric analyzer (TGA) in the temperature range of 25–1000 °C with heating rates of 10–30–50 °C min−1 under a nitrogen atmosphere. The synergetic effects of co-pyrolysis of two different waste feedstock were investigated. The kinetic parameters are determined using the Flynn–Wall–Ozawa (FWO) model. The results revealed that the mean values of apparent activation energy for the decomposition of sheep manure into a recycled polyethylene terephthalate blend are determined to be 86.27, 241.53, and 234.51 kJ/mol, respectively. The results of the kinetic study on co-pyrolysis of sheep manure with plastics suggested that co-pyrolysis is a viable technique to produce green energy.

“…Minerals in microalgae can provide chemical adsorption for heavy metals in OS during the thermal process, and microalgae have the potential to improve the pyrolysis characteristics of OS. Actually, the co‐pyrolysis of microalgae with other biomass, oil shale, or coal has been studied by many researchers. The results showed that the addition of microalgae could improve the pyrolysis performance of fuels to varying degrees.…”

The pyrolysis of oil sludge (OS) with microalgae residue (MR) additive was conducted with a TGA and a tube furnace. The pyrolysis process of OS with the MR additive can be divided into three stages: 1) water evaporation, 2) the release of light groups of hydrocarbon compounds, the cracking of heavy groups, and carbon decomposition, and 3) minerals decomposition. With the MR addition ratio increasing, the yield of oil and gas increased, and oil to gas ratio increased during OS pyrolysis. The MR addition improved the quality of pyrolysis oil and gas from OS pyrolysis. The proportion of light oil increased from 38 % with a 5 % MR addition ratio to 45 % with a 30 % addition ratio. Major components of pyrolysis gas included H 2 , CO, CO 2 , and C x H y . With the increase of the MR blending ratio, CO and CO 2 contents increased, while H 2 and C x H y contents decreased. Adding MR favoured the transformation of heavy hydrocarbons (C 6þ ), resulting in a high content of light hydrocarbons. This work can help promote massive synergistic treatment of OS and microalgae biomass.
