“…The choice of such method is dictated by its applicability across a very broad temperature and pressure range not displaying any anomalous behavior, unlike the activity coefficient property method 38. Moreover, this method has been used in the case studies 27, 35, 39 similar to the current work. The reactor was modeled using the Aspen PFR blocks, in line with Ranade et al 34 who claimed that the plug‐flow model is often applied for modeling of trickle‐bed reactors.…”

“…Process modeling and simulation was done in the Aspen Plus V11 (Aspen Technology) environment previously used in similar cases 2, 20, 27, 35. As arabinoic acid properties involved in modeling were not available in the Aspen Plus database, they were introduced to the simulation by a user‐defined compound wizard option using a properties table as shown in Tab.…”

The present work focuses on process design and techno‐economic assessment of the oxidation of a pentose sugar present in hemicelluloses, i.e., arabinose, on a supported gold catalyst. The processing plant was designed with Aspen Plus. The arabinose feedstock price has an important impact on the operational performance contributing to almost half of these costs. The feasibility of the overall arabinose oxidation process requires efficient extraction of hemicellulose from the lignocellulosic biomass lowering the feedstock costs.

A Short Overview on the Hydrogen Production Via Aqueous Phase Reforming (APR) of Cellulose, C6-C5 Sugars and Polyols

The use of lignocellulosic biomasses for the production of renewable hydrogen is surely among the hot-topic research tasks. In this review, we report on the recent advances in the catalytic conversion of cellulose and its derived C6-C5 sugars (glucose, fructose, and xylose) and polyols (sorbitol and xylitol) into hydrogen via aqueous phase reforming (APR) reactions. The APR processes are considered to be new sustainable catalytic routes for converting the carbohydrate fraction of biomasses into hydrogen at milder reaction conditions if compared with the traditional reforming reactions. Particular emphasis is given to the development of new and active catalysts and to the optimization of reaction conditions that aimed to maximize hydrogen production with a low concentration of CO avoiding, at the same time, the formation of alkanes.

“…The aqueous phase reforming reaction (APR) of oxygenated hydrocarbons was firstly introduced in 2002 by Dumesic et al [ 1 ] This approach represents an interesting step for the upgrading of sugars and polyols towards the production of hydrogen and liquid products in water at relatively low temperatures (150–250 °C) and pressures (15–60 bar) [ 2 , 3 , 4 ]. Among the use of ethylene glycol [ 3 , 5 , 6 , 7 , 8 ], glucose [ 9 , 10 , 11 , 12 ], and biomass-derived polyols [ 11 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ] as starting raw materials, glycerol represents an interesting substrate due to its availability as coproduct of biodiesel manufactures. In this context, glycerol conversion to high added value products is considered a key factor to boost the economic viability of biodiesel production.…”

Microemulsion Derived Titania Nanospheres: An Improved Pt Supported Catalyst for Glycerol Aqueous Phase Reforming

et al. 2021

Glycerol aqueous phase reforming (APR) produces hydrogen and interesting compounds at relatively mild temperatures. Among APR catalysts investigated in literature, little attention has been given to Pt supported on TiO2. Therefore, herein we propose an innovative titania support which can be obtained through an optimized microemulsion technique. This procedure provided high surface area titania nanospheres, with a peculiar high density of weak acidic sites. The material was tested in the catalytic glycerol APR after Pt deposition. A mechanism hypothesis was drawn, which evidenced the pathways giving the main products. When compared with a commercial TiO2 support, the synthetized titania provided higher hydrogen selectivity and glycerol conversion thanks to improved catalytic activity and ability to prompt consecutive dehydrogenation reactions. This was correlated to an enhanced cooperation between Pt nanoparticles and the acid sites of the support.
