“…However, these products are cracked during medium-and high-temperature carbonisation by the heat from the hot coke or the walls of the ovens to produce many complex reactions. In addition, water, methane, carbon monoxide, hydrogen sulphide and ammonia are eliminated, resulting in ring closure, aromatisation, condensation, and unsaturation [22].…”

Coal, a solid fossil fuel, consists of organic and inorganic matter. Its complex structure contains fused aromatic moieties, constituting a three‐dimensional macromolecular coal structure network. More efficient utilisation technologies are required to ensure coal becomes a considerably cleaner source of energy in the future. Due to the increase in energy, liquid fuels, and combustible gas demands, coal utilisation is necessary for some developing countries such as Pakistan, Turkey, and India. Furthermore, coal is globally being used to produce liquid fuels and combustible gases. The benefits and drawbacks of various Fischer‐Tropsch synthesis catalysts are discussed. For clean coal carbonisation, blends of coal and biomass, which are the current trends in decarbonising the coal industries, should be adopted and the chemistry of coal carbonisation should be investigated further, especially the phenomenon that occurs at the plastic layer (300–550 °C). In addition, the clean co‐gasification technology presented in this work could be adopted and successfully implemented through government and industry initiatives to study and test coal/biomass for co‐gasification and advanced modelling and simulation of the co‐gasification plant.

In this article, the impact of conventional carbon sources, alongside potential carbon bio‐sources, on slag‐foaming behavior is investigated. It highlights the complex relationship between these carbon sources and their properties, such as fixed carbon (FC), volatile matters (VMs), mineral composition in ash, reactivity, and wetting, which ultimately influence the slag foaming efficiency. The challenges associated with biochar and the significant differences in foaming behavior are addressed. For biochar to achieve effective slag foaming, it is essential that it contains an FC of at least 60 wt% and ash of less than 5 wt%. Though less impactful than CO generation from iron (II) oxide reduction, VMs from carbon sources, especially with high‐VM biochar, show secondary effects on reaction courses. The disadvantages associated with the high reactivity of biochar can be overcome by improving its physicomechanical and physicochemical properties. Despite the potential of biochar–coke mixtures to benefit slag foaming without enhancing biochar properties directly, challenges such as biochar floatation on the liquid slag surface and rapid burn‐off exist. Biocoke offers foaming results comparable to those of conventional sources. Despite the benefits of biocoke over other carbon sources, the review underscores its relatively unexplored status in the context of slag‐foaming applications.
