“…In this part, calculation of investment, capital cost, and revenue was conducted for CHDO and CTH process. The capital cost for manufacturing and facilities is defined as the total direct capital cost (TDC) ( Xiang et al, 2014 ; Zhou et al, 2019 ; Saavedra del Oso et al, 2020 ) which is estimated by the production capacity index approach, and it is defined as:

where m is the total unit in process design, C E,i is the capital cost of each process corresponding to actual capacity Q, C basic indicates the capital cost with the base case capacity, α is the cost scale factor, and f is a comprehensive adjustment factor ( Zhou et al, 2019 ; Cormos, 2021 ; Marchese et al, 2021 ). Q/Q basic is 1/1 for both CHDO and CTH processes, the ratio of which was determined based on previous literature ( Zhou et al, 2019 ; Cormos, 2021 ; Marchese et al, 2021 ).…”

Hydrogenolysis of glycerol to propylene glycol represents one of the most promising technologies for biomass conversion to chemicals. However, conventional hydrogenolysis processes are often carried out under harsh H2 pressures and temperatures, leading to intensive energy demands, fast catalyst deactivation, and potential safety risks during H2 handling. Catalytic transfer hydrogenolysis (CTH) displays high energy and atom efficiency. We have studied a series novel solid catalysts for CTH of glycerol. In this work, detailed studies have been conducted on energy optimization, tech-economic analysis, and environmental impact for both processes. The key finding is that relatively less energy demands and capital investment are required for CTH process. CO2 emission per production of propylene glycol is much lower in the case of transfer hydrogenolysis. The outcome of this study could provide useful information for process design and implementation of novel hydrogenolysis technologies for other energy and environmental applications.

“…C5-C9 iso-olefins, through the formation of intermediate carbocations (3), can lead to the formation of C5-C9 iso-paraffins and paraffins by hydrogenation reactions (4) or cyclopentadienyl groups by cyclization reactions (6). The cyclic anions evolve then to aromatic hydrocarbons by protons transfer reaction (7).…”

“…In this context, the aviation sector should develop alternative kerosene‐based fuels, with low greenhouse gas emissions and compatible with the existing technology and infrastructure, such as the synthetic paraffinic kerosene, formed mostly by C9‐C16 paraffinic hydrocarbons. The Fischer‐Tropsch synthesis (FTS) using synthesis gas obtained from renewable energy resources 3‐5 represents a competitive alternative to produce bio‐jet fuels compatible with the current technology 6‐8 …”

“…The Fischer-Tropsch synthesis (FTS) using synthesis gas obtained from renewable energy resources [3][4][5] represents a competitive alternative to produce bio-jet fuels compatible with the current technology. [6][7][8] FTS is the heterogeneously catalyzed conversion of hydrogen and carbon monoxide into a broad range of hydrocarbons and water. The FTS can also produce CO 2 if it is catalyzed by an iron-based catalyst since iron favors the water-gas shift activity.…”

Summary The Fischer‐Tropsch synthesis is considered to be an alternative process to produce liquid hydrocarbons in an environmentally sustainable way by using synthesis gas obtained from renewable resources. The combination of acid catalysts, such as zeolites, with Fischer‐Tropsch catalysts could lead to an increase in the selectivity to an specific range of hydrocarbons, such as synthetic paraffinic kerosene. Therefore, the conversion of synthesis gas in hydrocarbons within kerosene range using catalytic dual beds formed by a potassium‐cobalt‐promoted iron and zeolites H‐ZSM‐5 and H‐ZSM‐12 has been studied. The reactions have been carried out at 250°C, 20 bar in a stacked fixed dual bed using synthesis gas with a H2:CO molar ratio of 2 during 60 hours. The selectivity towards C9‐C16 hydrocarbons was increased from 25% using the FT catalyst without zeolite, and up to 30% by using zeolites H‐ZSM‐5 or H‐ZSM‐12 with a Si/Al of 30 and 60, respectively. The results allowed the development of a reaction scheme suitable to design a tunable process for the synthesis gas conversion.

The Paris COP21 held on December 2015 represented a step forward global GHG emission reduction: this led to intensify research efforts in renewables, including biofuels and bioliquids. However, addressing sustainable biofuels and bioliquid routes and value chains which can limit or reverse the ILUC (indirect land-use change effect) is of paramount importance. Given this background condition, the present study targets the analysis and modelling a new integrated biomass conversion pathway to produce renewable advanced fuels, enabling the issue of indirect land-use change (ILUC) of biofuels to be tackled. The bioenergy chain under investigation integrates the decentralized production of biogas through anaerobic digestion and its upgrading to biomethane, followed by a centralized conversion to liquid transport fuels, involving methane reforming into syngas, Fischer–Tropsch (FT) synthesis, and methanol synthesis. The methodology adopted in this work stem from extensive literature review of suitable bio/thermo-chemical conversion technologies and their process modelling using a commercial flow-diagram simulation software is carried out. The major significance of the study is to understand the different modelling approaches, to allow the estimation of process yields and mass/energy balances: in such a way, this work aims at providing guidance to process modellers targeting qualitative and quantitative assessments of biomass to biofuels process routes. Beyond FT products, additional process pathways have been also explored, such as MeOH synthesis from captured CO2 and direct methane to methanol synthesis (DMTM). The analysis demonstrated that it is possible to model such innovative integrated processes through the selected simulation tool. However, research is still needed as regards the DMTM process, where studies about modelling this route through the same tool have not been yet identified in the literature.
