The utilization of biogas as carbon source for the co-production of filamentous-like materials and syngas is proposed. Catalysts with different Ni:Al molar ratios, Al2O3 supports and preparation methods were synthesized. The suitability of the catalysts was analyzed considering activity, stability and carbon yield. Catalysts showed a good performance and similar results according to syngas comp...

Microwave pyrolysis of distillers dried grain with solubles (DDGS) was investigated to determine the effects of pyrolytic conditions on the yields of bio-oil, syngas, and biochar. Pyrolysis process variables included reaction temperature, time, and power input. Microwave pyrolysis of DDGS was analyzed using response surface methodology to find out the effect of process variables on the biofuel ...

Syngas, also known as producer gas or wood gas, is a gaseous biofuel produced by gasification of biomass. It mainly composed hydrogen and carbon monoxide with smaller share methane, all diluted nitrogen dioxide. Despite having in its composition, since it made from biomass, considered low to zero-carbon being so makes one candidate for reducing emissions internal combustion engines. This work f...

A newly designed inverted batch reactor equipped with a pressure-driven feeding system was built for investigating the kinetics of syngas during the steam hydrogasification (SHR) of biomass. The system could instantly load the feedstock into the reactor at high temperature and pressure, which simulated the way to transport the feedstock into a hot and pressurized gasifier. Experiments were cond...

The thermal valorization of glycerol to produce synthesis gas has been investigated under conventional and microwave heating systems. Different processes (pyrolysis, steam reforming and dry reforming) are compared, using a commercial activated carbon as catalyst. The reforming processes that employ oxidizing agents (CO2 or H2O) were found to promote higher glycerol conversions than mere termal ...

Great efforts have been spent to reduce the greenhouse gas (GHG) emissions and improve the efficiency of the Integrated Gasification Combined Cycle (IGCC). This study focuses on investigating two approaches to achieve these goals. First, replace the traditional subcritical Rankine steam cycle of the overall plant with a supercritical steam cycle. Second, add different amounts of biomass as feed...

Technical and economic analysis of thermal plasma–assisted Waste-to-Energy 2 EXECUTIVE SUMMARY Increasing interest is focusing on plasma-assisted gasification applied to the treatment of municipal solid waste (MSW), especially as it may be a new way to increase Waste-to-Energy (WTE) worldwide. The aim of this thesis was to investigate different such processes under development and their technic...

Initial results are presented for the production of hydrogen from waste lubricating oil using a chemical looping reforming (CLR) process. The development of flexible and sustainable sources of hydrogen will be required to facilitate a ‘hydrogen economy’. The novel CLR process presented in this paper has an advantage over hydrogen production from conventional steam reforming because CLR can use ...

The gasification of biomass is a promising technique to generate different forms of valuable alternative energy, including direct thermal energy and further conversion of synthesis gas to clean liquid fuels or chemicals via Fischer– Tropsch synthesis (FTS) [1–5]. The ideal H2/CO ratio for FTS is ~2/1 based on the stoichiometry. However, The H2/ CO for the synthesis gas obtained from biomass gas...
