Special Issue Information

Dear Colleagues,

H2 production from wastes will be a way of solving near future problems that involve the increasing demand of this raw material in industry; in addition, it has a potential use as an energy carrier. In this scenario, wastes, such as biomass and plastics, are attractive raw materials for producing renewable H2 with lower emission of greenhouse gases than by reforming natural gas, which is currently the main route for H2 production. Amongst the different conversion methods, one-step thermochemical routes (pyrolysis or gasification) are especially interesting for their industrial implementation and allow the obtainment of high H2 yields. An interesting alternative to the aforementioned strategies lies in performing pyrolysis and reforming steps using two in-line reactors, which allow for establishing the optimum conditions in each step for obtaining almost all the hydrogen contained in the feed. In order to progress towards the industrial implementation of these processes for H2 production, the development of highly active catalysts is essential. Moreover, the deactivation of the catalysts by coke deposition is the most important challenge of reforming processes.

This Special Issue on “Waste Valorization for Hydrogen Production: Advances in Reforming Catalysts” aims to curate novel advances in the development of catalysts for reforming processes. High-quality research studies and reviews dealing with synthesis of reforming catalysts and catalyst deactivation are particularly welcome.

Hydrogen is mainly produced by steam reforming of natural gas, a nonrenewable resource. Alternative and renewable routes for hydrogen production play an important role in reducing dependence on oil and minimizing the emission of greenhouse gases. In this work, butanol, a model compound of bio-oil, was employed for hydrogen production by steam reforming. The reaction was evaluated for 30 h in a tubular quartz reactor at 500 °C, atmospheric pressure, GHSV of 500,000 h−1, and an aqueous solution feed of 10% v/v butanol. For this reaction, catalysts with 20 wt.% NiO were prepared by wet impregnation using three supports: γ-alumina and alumina modified with 10 wt.% of cerium and lanthanum oxides. Both promoters increased the reduction degree of the catalysts and decreased catalyst acidity, which is closely related to coke formation and deactivation. Ni/La2O3–Al2O3 presented a higher nickel dispersion (14.6%) which, combined with other properties, led to a higher stability, higher mean hydrogen yield (71%), and lower coke formation per mass (56%). On the other hand, the nonpromoted catalyst suffered a significant deactivation associated with coke formation favored by its highest acidity (3.1 µmol m−²). Full article
