The conversion of biomass to a lowor medium-heating-value gaseous fuel (biomass gasification) generally involves two processes. The first process, pyrolysis, releases the volatile components of the fuel at temperatures below 600°C (1,112°F) via a set of complex reactions. Included in these volatile vapors are hydrocarbon gases, hydrogen, carbon monoxide, carbon dioxide, tars, and water vapor. B...

The providing and storage of hydrogen for efficient fuel cell systems is an on-going challenge. The partial catalytic dehydrogenation (PCD) of liquid fuels can provide stationary or mobile fuel cell systems with hydrogen. Through PCD, liquid fuels can be treated as hydrogen storage as well as an energy provider for combustion processes. It is also an alternative to the common reforming processe...

The increased number of automobiles in recent years has resulted in great demand for fossil fuel. This has led to the development of automobile by using alternative fuels which include gaseous fuels, biofuels and vegetables oils as fuel. Energy from biomass and more specific bio-diesel is one of the opportunities that could cover the future demand of fossil fuel shortage. Biomass in the form of...

In order to be able use the full potential of regenerative fuels, a comprehensive characterization is necessary identify differences between conventional fuels and fuels. current work, we compare OME 3−5 1-Octanol with diesel-like Dodecane in terms mixture formation under ECN Spray A conditions for single multi-injection. To determine mixtures, i.e., mass distribution resulting air-fuel equival...

The pyrolysis of briquettes made from biomass is an available and economic technological route for the production of briquette charcoal, but by-products (tar and gas) cannot be brought into full utilization, leading to the waste of resources and the addition of environmental concerns. Temperature is the most important parameter that affects the distributions and properties of briquette charcoal...

The use of ionic liquids (ILs) for gas separation processes recently has attracted much attention due to high solubilities of different gaseous species in ionic liquids [1]. The preparation of supported ionic liquid membranes (SILMs) is also reported for selective separation of different organic or gaseous compounds. Research activities have amongst others focused on CO2 separation from gas str...

The understanding of the gaseous adsorption process and the parameters of volatile organic compounds such as organic solvents or fuels onto soils is very important in the analysis of the transport or fate of these chemicals in soils. Batch adsorption experiments with six different treatments were conducted to determine the adsorption of isohexane, a gaseous aliphatic, onto volcanic ash soil (Ta...

Simulation and analysis of a turbulent free jet flame erupting into still air are done using computational fluid dynamics (CFD). Using 2D axisymmetric numerical modeling in ANSYS-Fluent 14.5. Three distinct kinds gaseous fuels used: methane, carbon monoxide, Biogas (50 % CH4 50 CO2). The effects thermal radiation utilizing the P-1 model on behavior investigated, impacts temperature fuel velocit...

To tackle the scale-up of Chemical Looping Processes, production efficient and affordable oxygen carriers appears paramount importance. Ilmenite is an ore-derived carrier which can be considered surely abundant cheap.
