Catalytic Reforming of Biogas for Syngas Production
… the quality of the fuel. Dry and auto-thermal reforming are catalytic methods that convert both the CH₄ and CO₂ into H₂ and CO, or syngas, a valuable product that can be used to produce liquid fuels, provide H₂ for fuel cells, or improve the combustion of biogas. A Rh/Al₂O₃ catalyst is …

Studies on Hydrogen Selective Silica Membranes and the Catalytic Reforming of CH₄ with CO₂ in a Membrane Reactor
… silica membranes were studied along with the catalytic reforming of CH₄ with CO₂ (CH₄ + CO z 2 CO + 2 H₂) in a hydrogen separation membrane reactor. The silica membranes were prepared by chemical vapor deposition (CVD) of a thin SiO₂ layer on porous supports (Vycor glass and alumina) using …

Predictive Modeling of Large-Scale Integrated Refinery Reaction and Fractionation Systems from Plant Data: Fluid Catalytic Cracking (FCC) and Continuous Catalyst Regeneration (CCR) Catalytic Reforming Processes
… and Fractionation Systems from Plant Data: Fluid Catalytic Cracking (FCC) Process with Planning Applications: This work presents the methodology to develop, validate and apply a predictive model for an integrated fluid catalytic cracking (FCC) process. We demonstrate the methodology by using data …

The autothermal reforming of artificial gasoline
… The production of hydrogen by the autothermal reforming of artificial gasoline has been studied. Part of gasoline is oxidised to produce heat and steam to promote the steam reforming of unburnt gasoline to produce hydrogen. The use of platinum impregnated on ceria supports (active for …

Non-thermal Plasma Assisted Catalytic Upgrading of Low-cost Hydrocarbons
The catalytic upgrading of low-cost hydrocarbons under mild conditions (< 100 ℃ and atmospheric pressure) is explored with the assistance of non-thermal plasma. This novel technology can effectively convert methane at near ambient temperature and atmospheric pressure. A methane conversion higher …

Ceramic Microreactors for on-Site Hydrogen Production
… on the other hand, show promise for efficient catalytic reforming of liquid hydrocarbons at high temperatures for on-board generation of H2 for fuel cell applications, thereby avoiding the need for H2 storage and transport. The present challenges encountered in the reforming of hydrocarbons, …

Bayesian inference of chemical reaction networks
… to the inference of reaction models for catalytic reforming of methane from a set of ~/~ 32000 possible models and real experimental data. We find that the use of adaptive MCMC makes large-scale inference of reaction networks feasible without the often extensive manual tuning that is …

Aerosol synthesis and Rietveld refinement of Pd2Zn
… replace current Cu catalysts for methanol steam reforming. The change in selectivity to CO2 that makes this a possibility has been attributed to the formation of tetragonal β1-PdZn at treatment temperatures of 500oC. Through the course of studying the phase evolution of the 1:1 PdZn, it was seen …

Catalytic Tar Reforming Using Biochar During Solid Waste Gasification
… that the most promising solution to tars is catalytic reforming. Alas, the catalysts are easily deactivated during the process. On the other hand, chars, which are a byproduct from gasification, have demonstrated their catalytic capabilities for tar reforming and are inexpensive. Although a …

Fast microwave-assisted thermochemical conversion of biomass for biofuel production
… developed. In Chapter 3, fast microwave-assisted catalytic co-pyrolysis of microalgae and scum on HZSM-5 catalyst for bio-oil production was investigated. The effects of co-pyrolysis temperature, catalyst to feed ratio, and microalgae to scum ratio on bio-oil yield and composition were examined. …
