Autothermal Reforming of Volatile Organic Compounds to Hydrogen-Rich Gas

Abstract

Industrial emissions of volatile organic compounds are urgently addressed for their toxicity and carcinogenicity to humans. Developing efficient and eco-friendly reforming technology of volatile organic compounds is important but still a great challenge. A promising strategy is to generate hydrogen-rich gas for solid oxide fuel cells by autothermal reforming of VOCs. In this study, we found a more desirable commercial catalyst (NiO/K2O-γ-Al2O3) for the autothermal reforming of VOCs. The performance of autothermal reforming of toluene as a model compound over a NiO/K2O-γ-Al2O3 catalyst fitted well with the simulation results at the optimum operating conditions calculated based on a simulation using Aspen PlusV11.0 software. Furthermore, the axial temperature distribution of the catalyst bed was monitored during the reaction, which demonstrated that the reaction system was self-sustaining. Eventually, actual volatile organic compounds from the chemical factory (C9, C10, toluene, paraxylene, diesel, benzene, kerosene, raffinate oil) were completely reformed over NiO/K2O-γ-Al2O3. Reducing emissions of VOCs and generating hydrogen-rich gas as a fuel from the autothermal reforming of VOCs is a promising strategy.

An in-depth physicochemical investigation of drug-loaded core–shell UiO66 nanoMOFs

“…has established itself as a powerful analytical tool to characterize nanomaterials, 24 and even to assess their drug delivery properties. 25,26 Particularly, hyphenated with inductively coupled plasma-mass spectrometry (ICP-MS), AF4-ICP-MS combines the extremely high elemental selectivity and ultratrace detection limits of the mass spectrometry with the capacity of AF4 to differentiate the diverse nanoparticle populations present in the sample. 27,28 However, to the best of our knowledge, it has not been applied so far to study drug loading in nanoMOFs.…”

Design and application of metal organic frameworks for heavy metals adsorption in water: a review

“…It is also important to invest in technologies and systems that can help reduce pollution and treat wastewater before it is released into the environment. 4–12 Heavy metals are a common inorganic pollutant found in contaminated water sources. These metals can be harmful to human health and wildlife, so it is important to reduce their concentration in polluted water.…”

A smart L‐alanine modified Cd‐NDI metal‐organic framework crystalline material: Photochromic properties and photocatalytic degradation dye applications

“…Metal–organic frameworks (MOFs) are promising crystalline porous materials constructed via the coordination interactions between organic linkers and metal ions (or clusters) 1–3 . The porous structures, and instinct insolubility make MOFs an ideal platform for heterogeneous catalysis, 4 photocatalysis, 5 adsorption, 6,7 gas storage and separation, 8–12 etc.…”
