Preparation of high-dispersion Ni/C catalyst using modified lignite as carbon precursor for catalytic reforming of biomass volatiles

In recent decades, the production of H 2 from biomass, waste plastics, and their mixtures has attracted increasing attention in the literature in order to overcome the environmental problems associated with global warming and CO 2 emissions caused by conventional H 2 production processes. In this regard, the strategy based on pyrolysis and in-line catalytic reforming allows for obtaining high H 2 production from a wide variety of feedstocks. In addition, it provides several advantages compared to other thermochemical routes such as steam gasification, making it suitable for its further industrial implementation. This review analyzes the fundamental aspects involving the process of pyrolysis-reforming of biomass and waste plastics. However, the optimum design of transition metal based reforming catalysts is the bottleneck in the development of the process and final H 2 production. Accordingly, this review focuses especially on the influence the catalytic materials (support, promoters, and active phase), synthesis methods, and pyrolysis-reforming conditions have on the process performance. The results reported in the literature for the steam reforming of the volatiles derived from biomass, plastic wastes, and biomass/plastics mixtures on different metal based catalysts have been compared and analyzed in terms of H 2 production.

“…Thus, conventional metal oxide supports, such us Al 2 O 3 , MgO, SiO 2 , TiO 2 or CeO 2 , have been extensively analyzed in the steam reforming of the volatiles derived from biomass pyrolysis [28,29]. Moreover, the use of alternatives supports, such as olivine [30], limonite [31], silica based materials like SBA-15, MCM-41 [32,33] or carbon based supports [34][35][36][37], are gaining increasing attention due to their lower cost. Yang et al [38] investigated the production of H 2 in the catalytic reforming of corncob pyrolysis volatiles using Ni, Co and Ni-Co based catalysts supported on acid washed Shengly lignite (AWSL), and attained the highest H 2 production (7.26 wt.…”

“…As research reports, metal Ti peaks were recorded at 35.0°, 38.3°, 40.0°, 53.0°, 62.8°, 69.5°, 70.6°, and 76.1° . Figure shows that the diffraction peaks of the Ti, Ru and Ir for RuO 2 /Ti and RuO 2 ‐IrO 2 /Ti are sharp, which indicates that the Ru and Ir in the RuO 2 /Ti and the RuO 2 ‐IrO 2 /Ti electrodes are highly crystalline . After the electrodes were annealed at 300, 450, and 600 °C, respectively, the Ru (44.0°) peak became sharper, indicating that the crystallinity and metal crystallite size were increased.…”

The electrochemical preparation of NaClO has been widely used for the production of industrial disinfectant. To reduce the cost of electrode preparation using the brushing method, this paper introduces a method for the electrodeposition for RuO2/Ti and RuO2‐IrO2/Ti preparation and NaCl solution electrolysis. The deposition of Ir improves the uniformity and stability of the RuO2/Ti electrode. The optimum preparation conditions and additive concentrations were investigated in detail through the orthogonal experiment. By adjusting the electroplating time, temperature and voltage, the electrode with a high content of available chlorine was synthesized successfully. The physicochemical properties of the as‐prepared RuO2/Ti and RuO2‐IrO2/Ti were determined by XRD, SEM‐EDS, and XPS, and the electrochemical performance and lifetime of the RuO2/Ti and RuO2‐IrO2/Ti was verified via an electrochemical workstation. Uniform and stable RuO2/TiO2 and RuO2‐IrO2/TiO2 were synthesized successfully for the electrolysis of the NaCl solution.
