Special Issue Information

Dear Colleagues,

Sustainability of the resources needed to supply energy and raw materials on a global scale is an issue of crucial importance. The constant increase in the costs of petroleum-derived raw materials and the ever-growing concern related to their environmental impacts have given considerable impetus to research focused on new products derived from renewable raw materials and to the development of technological solutions that reduce energy consumption, the use of hazardous substances, and waste production while promoting a model of sustainable development. The valorization of biomass is a viable and urgent alternative to traditional disposal processes, including in the field of renewable energy and biofuels.

Zeolites and zeotypes have been widely used in multiple processes linked to catalysis, adsorption, and separation in both conventional and sustainable refining concepts, showing excellent activity, superior thermal/hydrothermal stability, and unique shape-selectivity. Zeolites are the most important heterogeneous catalysts in industrial applications, and the number of processes catalyzed by them is continuously increasing.

It is with great pleasure that we invite you to submit your manuscript to the Special Issue “Conversion of Biomass and Biomass Derivatives Using Zeolite-Based Catalysts”, which will share the most recent developments on sustainable chemistry, biomass valorization, biofuels, biodiesel production, raw materials, and glycerol; essentially all kind of studies related to the application of zeolites and zeolite-type catalysts. Topics of interest may include the following: novel synthesis and characterization methods for developing zeolitic materials, composites, nanosized zeolites, functionalization/modification of zeolites, composites comprising natural and synthetic zeolites and porous matrices, conventional and emerging applications on different catalytic routes (homogeneous and heterogeneous catalysis), strategies to improve their catalytic properties and enhance catalytic performance, catalyst deactivation, catalysis by zeolite-based materials and host/guest interactions, and theoretical modeling of catalysis/adsorption by porous materials. Both experimental and theoretical contributions are of interest. Original research papers, communications, and review articles will be considered for publication.

Three common solid wastes (waste incineration fly ash, sewage sludge, and polluted soil) were the raw materials used in the synthesis of a geopolymer–type zeolite–like product, which was then used as a catalyst carrier to prepare a nickel hydrogenation catalyst for the catalytic hydrogenation of levulinic acid to γ–valerolactone. Under optimum synthesis conditions, the synthesized geopolymer zeolite has excellent structure and performance. The characterization results show that the composites have a three–dimensional network structure, and the pore structure is homogeneous mesoporous or microporous. In this work, the results of catalytic hydrogenation show that the yield of γ–valerolactone can achieve up to 94% using the synthesized catalyst, which is comparable to that of commercial catalysts and the concentrations of typical polluting heavy metals of Cu, Zn, Pb, and Cd in the reaction solution were all below the emission concentration limit (Class I standard) after five cycles of reaction. In summary, this geopolymer–type zeolite–like catalyst is cheap and has excellent performance; it is, therefore, expected to be widely used in catalysis instead of commercial carriers. Full article

Silica supported sulfuric acid (SSA) has been demonstrated to be capable of effectively removing phenyl VOCs through the reaction-type adsorption mechanism. The effects of the solvent (water, ethyl acetate) used to impregnate silica gel with H2SO4 solution in order to prepare SSA adsorbents have been studied. As-prepared two series SSA(E)-x and SSA(W)-x materials (x = 1, 2, 3, 4) were characterized by TG, SEM/EDS and N2 adsorption/desorption techniques, and their breakthrough adsorption performances were evaluated from experimental and theoretical aspects. The results showed that the H2SO4 loading amounts were 2.8, 4.0, 4.8 and 5.6 mmol g−1 respectively for both SSA(E)-x and SSA(W)-x when x equaled 1, 2, 3, 4. Among them, SSA(E)-4 was found to have a higher proportion of the C-state H2SO4 than SSA(W)-4. Both SSA(E)-x and SSA(W)-x exhibited significant removal capacity of gaseous o-xylene. The reactive temperature regions were determined to be 120–170 °C for SSA(E)-4 and 120–160 °C for SSA(W)-4 with a common optimum point of 160 °C. Both SSA(E)-x and SSA(W)-x adsorbents exhibited excellent recyclability and reuse performance. Further, the series SSA(E)-x materials outperformed the series SSA(W)-x on all adsorption performance metrics, suggesting that ethyl acetate is a preferred solvent for preparing the SSA materials in phenyl VOCs removal application.

Originating from deoxygenation (DO) technology, green diesel was innovated in order to act as a substitute for biodiesel, which contains unstable fatty acid alkyl ester owing to the existence of oxygenated species. Green diesel was manufactured following a process of catalytic DO of sludge palm oil (SPO). An engineered Mn(0.5%)-Mo(0.5%)/AC catalyst was employed in a hydrogen-free atmosphere. The influence of Manganese (Mn) species (0.1–1 wt.%) on DO reactivity and the dissemination of the product were examined. The Mn(0.5%)-Mo(0.5%)/AC formulation gave rise to a superior harvest of approximately 89% liquid hydrocarbons; a higher proportion of diesel fraction selectivity n-(C15+C17) was obtained in the region of 93%. Where acid and basic active sites were present on the Mn(0.5%)-Mo(0.5%)/AC catalyst, decarboxylation and decarbonylation reaction mechanisms of SPO to DO were enhanced. Evidence of the high degree of stability of the Mn(0.5%)-Mo(0.5%)/AC catalyst during five continuous runs was presented, which, in mild reaction conditions, gave rise to a consistent hydrocarbon harvest of >72% and >94% selectivity for n-(C15+C17).
