Biochar is an efficient catalyst for tar removal from syngas during biomass gasification. The aim of this research to investigate the mechanism reforming using biochar as a catalyst. A series in situ steam experiments were carried out two-stage fluidized-bed/fixed-bed reactor at 800 °C. Mallee wood (106–250 μm) was activated 15 vol% H2O balanced with Ar different times (0–50 min) and then used ...

Decarbonization of the energy sector is a topic paramount importance to avoid irreversible global warming. Hydrogen has been considered as most suitable option replace fossil fuels in industrial, residential and transport applications. However, hydrogen production almost limited reforming hydrocarbons, which release large amounts CO2, thus requiring several downstream purification processes. Ca...

This paper documents the application of exhaust gas fuel reforming of two alternative fuels, biodiesel and bioethanol, in internal combustion engines. The exhaust gas fuel reforming process is a method of on-board production of hydrogen-rich gas by catalytic reaction of fuel and engine exhaust gas. The benefits of exhaust gas fuel reforming have been demonstrated by adding simulated reformed ga...

Aqueous phase reforming of glycerol was studied over a series of γ-Al2O3 supported metal nanoparticle catalysts for hydrogen production in a batch reactor. Of the metals studied, Pt/Al2O3 was found to be the most active catalyst under the conditions tested. A further systematic study on the impact of reaction parameters, including stirring speed, pressure, temperature, and substrate/metal molar...

The interest in Gas-to-Liquid technology (GTL) is growing worldwide because it involves a two-step indirect conversion of natural gas to higher hydrocarbons ranging from Liquefied Petroleum Gas (LPG) paraffin wax. GTL makes possible obtain clean diesel, naphtha, lubes, olefins, and other industrially important organics gas. This article brief review discussing the state-of-the-art GTL, includin...

This paper presents the formulation of a controller for a Catalytic Flow Reversal Reactor (CFRR) with heat extraction. The controller is based on the Model Predictive Control (MPC) concept. The MPC scheme uses a model that assumes plug flow and neglects radial gradients in the reactor but accounts for the two phases within the reactor. The prediction of the future output behavior from the model...

A series of nickel-containing mesoporous silica samples (Ni-SiO₂) with different nickel content (3.1%-13.2%) were synthesized by the evaporation-induced self-assembly method. Their catalytic activity was tested in carbon dioxide reforming of methane. The characterization results revealed that the catalysts, e.g., 6.7%Ni-SiO₂, with highly dispersed small nickel particles, exhibited excellent cat...

Abstract Herein, the promotion effect of only 0.3 wt% indium on 3% Ni/Al2O3 and Ni/CeO2-Al2O3 catalysts prepared by deposition-precipitation over a commercial alumina CeO2-modified support was studied. Catalyst characterization XRD, TPR, XPS, TEM, CO-DRIFTS performed. The catalytic properties were investigated coke formation analyzed under temperature ramped CH4-decomposition in Dry Reforming M...

The coupling of reactions in catalytic membrane reactors provides novel reactor configurations that allow shifting the thermodynamic equilibrium and yields of thermodynamically limited reactions and enhancing significantly the rate of production. An interesting pair to couple is the dehydrogenation of ethylbenzene to styrene and the hydrogenation of nitrobenzene to aniline. Hydrogen produced in...
