“…However, for the OPS, the C and O contents were evidently lower at higher pyrolysis temperatures. These results clearly showed that the pyrolysis of biomass produced biochar with a high C content and a low O content, which is similar to the findings of the previous studies (Maddi et al, 2011;Alvarez et al, 2015;Bensidhom et al, 2018). The higher C content and lower O content of the biochar led to superior HHV.…”

“…These HHVs were relatively low when compared to the studies of Pattiya and Suttibak (2012b) and Sirijanusorn et al (2013), who performed the pyrolysis of cassava biomass with a fast pyrolysis reactor. Kabir et al (2017) and Bensidhom et al (2018) also found that the HHV of bio-oil was 21-25 MJ/kg. Table 4 presents the compounds of the liquid product obtained from the OPT, OPF, and OPS at a pyrolysis temperature of 500°C.…”

“…However, the liquid product samples contained low amounts of N and S since the biomass used in this study had low N and S contents. The hydrocarbon content of bio-oil with low water contents can range from 60-80 wt.% (Pattiya and Suttibak, 2012b; Kabir et al, 2017;Bensidhom et al, 2018). For the HHV of the liquid product, this study determined the HHV of water-free liquid product.…”

“…In spite of the above-mentioned advantages, the pyrolysis of biomass is still challenging due to the quantity and quality of the pyrolysis products being affected by many factors, including pyrolysis type, type of reactor, operating parameters, as well as biomass type and properties (Domínguez et al, 2006;Maddi et al, 2011;Pattiya, 2011;Pattiya and Suttibak, 2012a Kabir et al, 2017). However, the application of OPT and OPF biomass for the production of biofuels using pyrolysis processes is still a challenge as there are only a few studies that have investigated the pyrolysis of OPT and OPF (Yakub et al, 2015;Sareekam et al, 2016;Bensidhom et al, 2018), necessitating further studies to obtain in-depth insights into the process. In light of that, this study was aimed to investigate the yields and qualities of pyrolysis products obtained from OPT, OPF, and OPS using an agitated pyrolysis reactor.…”

“…13 Pyrolysis is the process to convert the waste into environment-friendly products in the absence of oxygen and heating the biomass at elevated temperature in the range of 300°C to 700°C. 14 The heating rate determines the yield of bio-oil, char, and syngas production. The slow pyrolysis yields the high amount of char which can, in turn, be useful for soil amendment application.…”

Carbon conversion and stabilisation of date palm and high rate algal pond (microalgae) biomass through slow pyrolysis

et al. 2019

Summary The processing of waste through pyrolysis technology is gaining momentum worldwide and is considered to be a green technology to reduce CO2 emissions. This study is devoted to analysing the lignocellulosic biomass (date palm) and wastewater‐derived microalgae and the carbon‐rich char produced between temperature range (400°C‐600°C) from these biomass types. The properties of microalgae char showed that significant variation with date palm char exhibited high heating values (24‐28 MJ/kg), low ash content (11%‐16%), and high energy yield (48%‐42%). Algal biomass char showed considerably high nitrogen content (6%‐7%) as compared with date palm char (<1%), lower stability, and more significant influence on the price with respect to treatment temperature. Quaternary, pyrrolic, and pyridinic nitrogen species were found on the surface of the microalgae char, whereas no nitrogen species detected on date palm char due to low nitrogen content. The activation energy was also noted to be high for algal char during pyrolysis and combustion process. It can be concluded that date palm char is suitable for energy applications, whereas, algal char can be used for soil amendment, wastewater treatment, and applications requiring nitrogen‐doped char.

Research and technology development in the field of residual biomass exploitation for the production of biofuels is advancing. Non-food waste could form an excellent feedstock for biofuel generation. Residual biomass of food or first generation biofuels industries forms an ideal feedstock for fuel production forming simultaneously an environmentally friendlier solution for their disposal. A number of challenges are associated with waste-biomass exploitation as collection, transportation and their management can dramatically affect the economics of the processes. The economics can however be improved if added value products are extracted prior to their treatment for biofuels. Furthermore, technological challenges related to feedstock quality and quantity variations have to be resolved. In this section, promising biomass for the characterization and the potential exploitation of which, substantial research is already in place is presented. The relevant biomass is, or has the potential to be abundant and its exploitation in the near future is realistic and possible.
