“…This can be achieved by either evaluating the properties of hierarchical zeolites using a single method comprising different degrees of mesoporosity (Fig. Although several works have reported the superior performance of bifunctional faujasite catalysts, 21,93,94 the role of external surface in the preparation of bifunctional catalysis is relatively unclear. Especially in studies contacting USY zeolites with CTA + -containing alkaline solutions, such systematic approaches should help to more precisely unravel the relationships between synthesis, properties, and function, crucial to the application-oriented design of hierarchical faujasites (Fig.…”

Faujasite (X, Y, and USY) zeolites represent one of the most widely-applied and abundant catalysts and sorbents in the chemical industry. In the last 5 years substantial progress was made in the synthesis, characterisation, and catalytic exploitation of hierarchically-structured variants of these zeolites. Hererin, we provide an overview of these contributions, highlighting the main advancements regarding the evaluation of the nature and functionality of introduced secondary porosity. The novelty, efficiency, versatility, and sustainability of the reported bottom-up and (predominately) top-down strategies are discussed. The crucial role of the relative stability of faujasites in aqueous media is highlighted. The interplay between the physico-chemical properties of the hierarchical zeolites and their use in petrochemical and biomass-related catalytic processes is assessed.

Early‐Stage Comparative Sustainability Assessment of New Bio‐based Processes

Our increasing demand for materials and energy has put critical roadblocks on our path towards a sustainable society. To remove these roadblocks, it is important to engage in smart research and development (R&D). We present an early-stage sustainability assessment framework that is used to analyze eight new bio-based process alternatives developed within the CatchBio research consortium in the Netherlands. This assessment relies on a multi-criteria approach, integrating the performance of chemical conversions based on five indicators into an index value. These indicators encompass economics, environmental impact, hazards and risks thereby incorporating elements of green chemistry principles, and techno-economic and life cycle assessments. The analyzed bio-based options target the production of fuels and chemicals through chemical catalysis. For each bio-based process, two R&D stages (current laboratory and expected future) are assessed against a comparable conventional process. The multi-criteria assessment in combination with the uncertainty and scenario analysis shows that the chemical production processes using biomass as feedstock can provide potential sustainability benefits over conventional alternatives. However, further development is necessary to realize the potential benefits from biomass gasification and pyrolysis processes for fuel production. This early stage assessment is intended as an input for R&D decision making to support optimal allocation and utilization of resources to further develop promising bio-based processes.

“…Similar results have also been obtained for mesoporous beta-supported Ru catalysts. [85][86][87][88] Rangel and co-workers investigated the catalytic performance of a meso-beta-supported cobalt catalyst. The use of H-meso-beta-0.15 m with a stronger acidity as the support for Ru nanoparticles (mean Ru diameter = 7.2 nm) resulted in a slightly lower C 5 -C 11 selectivity (67 %), but the C iso /C n ratio increased to about 3.5.…”

Fischer-Tropsch synthesis is a key reaction in the utilization of non-petroleum carbon resources, such as methane (natural gas, shale gas, and biogas), coal, and biomass, for the sustainable production of clean liquid fuels from synthesis gas. Selectivity control is one of the biggest challenges in Fischer-Tropsch synthesis. This Minireview focuses on the development of new catalysts with controllable product selectivities. Recent attempts to increase the selectivity to C5+ hydrocarbons by preparing catalysts with well-defined active phases or with new supports or by optimizing the interaction between the promoter and the active phase are briefly highlighted. Advances in developing bifunctional catalysts capable of catalyzing both CO hydrogenation to heavier hydrocarbons and hydrocracking/isomerization of heavier hydrocarbons are critically reviewed. It is demonstrated that the control of the secondary hydrocracking reactions by using core-shell nanostructures or solid-acid materials, such as mesoporous zeolites and carbon nanotubes with acid functional groups, is an effective strategy to tune the product selectivity of Fischer-Tropsch synthesis. Very promising selectivities to gasoline- and diesel-range hydrocarbons have been attained over some bifunctional catalysts.
