“…The An experimental setup was built to investigate the production of PEMFC-grade hydrogen from mixed reforming of a model feed gas mixture (flue gas + flare gas + steam) by means of a dense Pd77-Ag23 MR packed with a non-commercial Ni(7.5 wt%)/CeO2 catalyst provided by CNR-ITAE (Messina, Italy), chosen for its low cost and high coke resistance [77,78].…”

A rise in CO2 and other greenhouse gases’ concentration from gas refinery flares and furnaces in the atmosphere causes environmental problems. In this work, a new process was designed to use waste gas (flue gas and flare gas) of a domestic gas refinery to produce pure hydrogen in a membrane reactor. In particular, the process foresees that the energy and CO2 content of flue gas can provide the heat of the mixed reforming reaction to convert flare gas into hydrogen. Furthermore, the characteristics of the feed stream were obtained via simulation. Then, an experimental setup was built up to investigate the performance of a membrane reactor allocating an unsupported dense Pd-Ag membrane at the mentioned conditions. In this regard, a Ni/CeO2 catalyst was loaded in the membrane reformer for mixed reforming reaction, operating at 450 °C, in a pressure range between 100 and 350 kPa and a gas hourly space velocity of around 1000 h−1. The experimental results in terms of methane conversion, hydrogen recovery and yield, as well as products’ compositions are reported. The best results of this work were observed at 350 kPa, where the MR was able to achieve about 64%, 52% and 50% for methane conversion, hydrogen yield and recovery, respectively. Furthermore, with the assistance of the experimental tests, the proposed process was simulated in the scaling up to calculate the needed surface area for MR in the domestic gas refinery.

Review of Recent Studies on Solution Combustion Synthesis of Nanostructured Catalysts

Solution combustion synthesis (SCS) is a relatively new method for synthesizing catalytic materials with many distinct advantages: simplicity of method, short reaction times, and the capability to regulate crystal lattice parameters and thereby the activity and selectivity of catalysts. Over the last years, SCS has been used for the production and study of a multitude of new catalytic materials. This review considers and discusses the recent developments and trends in SCS of nanocatalysts, while special attention is paid to the development and applications of nanostructured catalysts.

“…In the last decade, there have been studies focused on the use of membrane reactors for producing hydrogen via biofuel reforming for onboard applications. 52,53 Potential benefits of using membrane technology include: (1) hydrogen production and separation in a single device; (2) production of a highly pure hydrogen stream (99.999% purity), which can be directly fed into a fuel cell for electricity generation; and (3) production of a concentrated CO 2 stream that may be reliably stored, thereby making the process CDR technology. In fact, the application of reactor technology to biofuel reforming may be a future CDR option for the transportation sector.…”

The current global dependence on fossil fuels to meet energy needs continues to increase. If a 2°C warming by 2100 is to be prevented, it will become important to adopt strategies that not only avoid CO2 emissions but also allow for the direct removal of CO2 from the atmosphere, enabling the intervention of climate change. The primary direct removal methods discussed in this review include land management and mineral carbonation in addition to bioenergy and direct air capture with carbon capture and reliable storage. These methods are discussed in detail, and their potential for CO2 removal is assessed. The global upper bound for annual CO2 removal was estimated to be 12, 10, 6, and 5 GtCO2/year for bioenergy with carbon capture and reliable storage (BECCS), direct air capture with reliable storage (DACS), land management, and mineral carbonation, respectively—giving a cumulative value of ~35 GtCO2/year. However, in the case of DACS, global data on the overlap of low‐emission energy sources and reliable CO2 storage opportunities—set as a qualification for DAC viability—were unavailable, and the potential upper bound estimate is thus considered conservative. The upper bounds on the costs associated with the direct CO2 removal methods varied from approximately $100/tCO2 (land management, BECCS, and mineral carbonation) to $1000/tCO2 for DACS (again, these are the upper bounds for costs). In this review, these direct CO2 removal technologies are found to be technically viable and are potentially important options in preventing 2°C warming by 2100.
