Biomass-based solutions have been discussed as having the potential to replace fossil-based solutions in the iron and steel industry. To produce the biocarbon required in these processes, thermochemical treatment, pyrolysis, typically takes place. There are various ways to produce biocarbon, alongside other products, which are called pyrolysis oil and pyrolysis gas. These conversion methods can be divided into conventional and non-conventional methods. In this paper, those techniques and technologies to produce biocarbon are summarized and reviewed. Additionally, the effect of different process parameters and their effect on biocarbon yield and properties are summarized. The process parameters considered were final pyrolysis temperature, heating rate, reaction atmosphere, pressure, catalyst, use of binders, and particle size. Finally, the effect of different reactor configurations is discussed. Understanding the combination of these methods, technology parameters, and reactor configurations will help to produce biocarbon with the desired quality and highest yield possible.

“…Volatile matter content was 47.43%, generally considered acceptable for ignition and combustion processes [4,27]. Different from other biomasses, yak manure had a higher ash content (34.36%) [28][29][30]. A higher ash content has the potential tendency to reduce the heating value.…”

This study was first conducted to comprehensively investigate the potential of yak manure as a raw material to prepare fuel pellets. The effect of different parameters such as binder, pressure, and moisture content on pellet density and diametric compressing strength was investigated using a laboratory single pelleting press unit. Results showed that increasing the pressure can help to obtain high-quality fuel pellets. The pellet properties (density and diametric compressing strength) initially increased and then decreased with moisture content increase. By contrast, binder was not identified to promote density and diametric compressing strength. The parameters were optimized using the response surface method with central composite design to obtain high-quality pellets. In conclusion, the use of yak manure as a raw material to make fuels can be considered a sustainable approach and can effectively be used to fulfill the energy and heating requirements of rural areas.

“…To make transportation and further energy processing easier, these wastes were subjected to densification that is based on their briquetting, tableting, or also pelletizing. In these technological operations, binders of various types were used [1], namely recovered polyvinyl alcohol, waste cooking oil and waste lubricating oil [2], lignin, starch and polyvinyl alcohol [3], xanthan and guar gums [4], pea starch, and carboxymethyl cellulose [5]. The binders for biomass were chosen with regard to the improvement of process-it has not been fully explained and requires additional research.…”

An Analysis of the Influence of Low Density Polyethylene, Novolac, and Coal Tar Pitch Additives on the Decrease in Content of Impurities Emitted from Densified Pea Husks during the Process of Their Pyrolysis

2023

The course of pyrolysis of pea husks was studied. It was stated that the compaction of a sample during its pyrolysis causes an almost two-fold increase in the content of hydrocarbons in the composition of volatile products in the temperature range of 350–470 °C. Low density polyethylene (LDPE), novolac, and coal tar pitch (CTP) wastes were added to feedstocks in the amount of 2 wt% in order to decrease the contribution of saturated and unsaturated hydrocarbons along with oxygen-containing compounds in volatile products. The analysis of the obtained products of pyrolysis was conducted using the techniques of thermogravimetry/Fourier transform infrared spectroscopy (TG/FT-IR), attenuated total reflectance (ATR) and ultraviolet (UV)-spectroscopies, gas chromatography-mass spectrometry (GCMS), X-ray diffractions (XRD), scanning electron microscopy (SEM), and energy dispersive X-ray analysis (EDX). It was determined that pitch took the first place in a series of effectiveness in decreasing the content of harmful compounds in pyrolysis products; novolac was the second. A temperature of 370 °C (CTP) lowers the contribution of compounds with carbonyl groups (by approx. 2.7 times) and the contribution of alcohols, phenols, and esters (by approx. 4.4 times). At a temperature of 465 °C, this additive reduces the contribution of saturated and unsaturated hydrocarbons in the composition of volatiles (by approx. 5.8 times) and at a temperature of 520 °C, a more substantial decrease is observed (by approx. 14.3 times). During the pyrolysis in the temperature range of 420–520 °C, LDPE actively emits its own products of decomposition in the form of aliphatic hydrocarbons that negatively affect the environment. The composition of condensed pyrolysis products changes under the influence of additives. In water condensates, the concentration of determined phenols and anhydrosugars increases slightly under the influence of additives. The SEM and XRD investigations proved that inorganics interact with volatile pyrolysis products from the blends of pea husks with additives and change their composition. After the transformation of chemical composition, inorganics catalyse secondary reactions that take place in the pyrolysis products of blends.
