“…The main reactor configurations developed in the literature for H2 production from hydrocarbons (such as plastic wastes) and oxygenates (such as biomass-derived compounds) should be classified into two main strategies [26,95]: (i) off-line reforming or (ii) pyrolysis with in-line (sequenced) reforming.…”

“…The most common catalytic thermochemical process intended for H2 production from hydrocarbons (CaHb, such as plastic wastes) and oxygenated hydrocarbons (CnHmOk, such as biomass-derived compounds) is the reforming process [9,26,27]. This may be conducted under several operating conditions, the most extensively studied being that performed with steam cofeeding, namely steam reforming, since it gives the maximum theoretical yield of hydrogen and is responsible for 78 % of the world H2 production [11].…”

“…In this scenario, the development of sustainable H 2 production technologies plays a significant role [1][2][3], with a special interest in the routes from lignocellulosic biomass [4,5] due to its high availability and whose valorisation does not interfere in the feeding chain. Among these routes from biomass, great attention is paid to the H 2 production by steam reforming (SR) of bio-oil, the liquid product from the pyrolysis of lignocellulosic biomass [6][7][8].…”

Several Ni catalysts of supported (on La 2 O 3 -αAl 2 O 3 , CeO 2 , and CeO 2 -ZrO 2 ) or bulk types (Ni-La perovskites and NiAl 2 O 4 spinel) have been tested in the oxidative steam reforming (OSR) of raw bio-oil, and special attention has been paid to the catalysts' regenerability by means of studies on reaction-regeneration cycles. The experimental set-up consists of two units in series, for the separation of pyrolytic lignin in the first step (at 500 • C) and the on line OSR of the remaining oxygenates in a fluidized bed reactor at 700 • C. The spent catalysts have been characterized by N 2 adsorption-desorption, X-ray diffraction and temperature programmed reduction, and temperature programmed oxidation (TPO). The results reveal that among the supported catalysts, the best balance between activity-H 2 selectivity-stability corresponds to Ni/La 2 O 3 -αAl 2 O 3 , due to its smaller Ni 0 particle size. Additionally, it is more selective to H 2 than perovskite catalysts and more stable than both perovskites and the spinel catalyst. However, the activity of the bulk NiAl 2 O 4 spinel catalyst can be completely recovered after regeneration by coke combustion at 850 • C because the spinel structure is completely recovered, which facilitates the dispersion of Ni in the reduction step prior to reaction. Consequently, this catalyst is suitable for the OSR at a higher scale in reaction-regeneration cycles.

“…The biomass gasification process has been widely studied and the technology has been developed for several reasons, such as the availability of biomass resources, producing a mixture of combustible gases that can be used as fuels, or as intermediate products in the large-scale production of fuels and chemicals. 10 Biomass gasification is usually carried out at temperatures of 700-1200°C, using air, oxygen, steam, or their mixtures as gasifying agents, which leads to a mixture of gaseous products composed of mainly syngas (mixture H 2 and CO), CO 2 , CH 4 , and other hydrocarbons. 11 The use of steam as a gasifying agent serves to increase H 2 composition and produce gases with high heating value, absent of nitrogen.…”

The availability of natural gas as feedstock for nitrogen fertilizer production continues to decline, while its price increases, encouraging the search for renewable feedstocks for the future green urea industry. Renewable feedstocks include waste biomass, hydrogen from solar PV‐electrolysis, and the combination of these feedstocks with natural gas. The selection of a green production strategy is a critical step in the trade‐off between economic and environmental considerations. The aim of this work was to propose a green urea production strategy using a multi‐objective optimization (MOO) model to minimize production costs and environmental impacts by considering the future cost development of technologies and feedstock price for each technology in the time frame of 2020‐2050. The results show that green urea production can reduce production costs and greenhouse gas emissions, compared to conventional urea production. Biomass gasification technology fulfills the minimum requirements for production cost and CO2 emissions from 2020 to 2035 and combined biomass gasification‐PV electrolysis without battery technology is the optimum process from 2040 to 2050.
