“…Nevertheless, most of these studies have been performed in batch operation using a two-step fixed bed reactor. Thus, Kannari et al 159 used chicken droppings (CD) and chicken dropping ash (CDA) as catalytic support on a Ni based catalyst for decomposing tar derived from Japanese cypress pyrolysis. The results revealed that Ni/CDA leads to higher H 2 production than the commercial Ni/Al 2 O 3 catalyst (5.8 wt % vs 5.0 wt % daf) and a lower amount of carbon deposition.…”

In recent decades, the production of H 2 from biomass, waste plastics, and their mixtures has attracted increasing attention in the literature in order to overcome the environmental problems associated with global warming and CO 2 emissions caused by conventional H 2 production processes. In this regard, the strategy based on pyrolysis and in-line catalytic reforming allows for obtaining high H 2 production from a wide variety of feedstocks. In addition, it provides several advantages compared to other thermochemical routes such as steam gasification, making it suitable for its further industrial implementation. This review analyzes the fundamental aspects involving the process of pyrolysis-reforming of biomass and waste plastics. However, the optimum design of transition metal based reforming catalysts is the bottleneck in the development of the process and final H 2 production. Accordingly, this review focuses especially on the influence the catalytic materials (support, promoters, and active phase), synthesis methods, and pyrolysis-reforming conditions have on the process performance. The results reported in the literature for the steam reforming of the volatiles derived from biomass, plastic wastes, and biomass/plastics mixtures on different metal based catalysts have been compared and analyzed in terms of H 2 production.

“…While the tar conversions provided by ashes are not particularly significant, catalysts based in ashes can be cheaply synthetized. The inorganic species in the ashes also are known to increase the activity of metal catalysts for converting hydrocarbons, and favour the water gasshift for inhibition of soot deposition and H 2 production [99,155]. Hence, further research to improve the activity of catalysts based in ashes will certainly pay off.…”

The presence of tars in syngas is a major technological constraint for upscaling biomass gasification to produce heat, power, and other value-added chemicals such as biofuels. At the same time, the solid remains from biomass gasification i.e. char and ashes, have capabilities to catalyse the reforming of gasification tars. This work presents a comprehensive analysis of the relevance of gasification chars and ashes as catalysts for tar reforming. A description of the solid products from biomass gasification, their formation, chemical characteristics and potential applications is given. Additionally, a review of the state of the art of the uses of regular char, activated carbon and ashes as a catalyst for tar reforming is presented. Further, kinetics reported in literature, and the homogeneous and heterogeneous mechanisms for tar reforming over char are discussed and explained. From reviewing literature it was found that activated chars exhibit the best reforming capabilities, followed by regular char and ashes. Knowing the role of the interactions between the char and the tars is a key factor for optimization of char catalysts. Ultimately, this work provides guidance for understanding the uses of biomass solids as catalysts for tar reforming, and aid in future research to increase the economic feasibility of biomass gasification.

“…The noble metal catalysts and the molecular sieve catalysts have better directional catalytic effects, but because of their high cost, they are not suitable for large-scale industrial applications. Molecular sieve catalysts prompt the deposition of carbon during pyrolysis because of their small pore size, which requires frequent regeneration treatments (Kannari et al 2017;Liu et al 2019). Some natural ore catalysts (e.g., calcined dolomite, limestone, olivine) have high catalytic activities, are inexpensive, and are easy to derive, but they do not easily deposit carbon and coke during pyrolysis.…”

Three kinds of pore-forming agents (corn flour, starch, and biochar) were selected to prepare dolomite-based porous ceramic catalyst carriers with good mechanical properties. Pore-forming agents occupy space within preformed agglomerates, such that after the pyrolysis and sintering have been completed there are spaces within the resulting ceramic material. Porous ceramic samples prepared with biochar exhibited high apparent porosity and water absorption. By contrast, the apparent porosity of the porous ceramic samples prepared with starch as the pore-forming agent was low. When the ratio of the dolomite to quartz sand in the ceramic aggregate was changed from 4:6 to 3:7, the change of the apparent porosity of the porous ceramic samples made with starch as a pore-forming agent was very small, with high bulk density and compressive strength. Compared with corn flour and biochar, starch was less suitable as a pore-forming agent for porous ceramics. The apparent porosity and water absorption of the porous ceramics prepared with biochar as a pore-forming agent decreased slightly. But its bulk density and thermal conductivity were increased. This is mainly attributable to the fact that biochar is lighter, but it performs well in terms of mechanical strength and thermal conductivity.
