An overview on gasification of biomass for production of hydrogen rich gas
نویسنده
چکیده
Gasification was chosen as one of the more conventional methods for conversion of biomass due to some important reasons such as space consideration, flexibility of fuels used, reducing the volume of solid waste and recovery of energy. Essentially, the process of gasification involves partial combustion of the organic part of the fuels to combustible gas rich in carbon monoxide, hydrogen and some saturated hydrocarbon gases, principally methane. The affecting parameters on the performance of the gasification such as (temperature, catalysts, gasifying agent/biomass ratio) and the type of raw materials were reviewed and discussed. _____________________________________________________________________________________________

Production of Hydrogen and Synthesis gas via Cu-Ni/Al2O3 catalyzed gasification of bagasse in supercritical water media
Bagasse as a real biomass was converted to hydrogen rich gas via catalytic supercritical water gasification process. To find the effect of Cu on selectivity of products, Cu promoted Ni-γAl2O3 catalysts were prepared with 1 to 20wt% Ni and 0.5 to 10wt% Cu loadings via impregnation method. Catalysts were characterized by ICP, BET, XRD, H2 chemisorption and TEM technique as well CHNS analysis was ...
متن کاملHydrogen rich gas production via nano-catalytic gasification of bagasse in supercritical water
Ru/Al2O3 nano-catalysts were prepared with impregnation and microemulsion techniques. The supercritical water gasification reaction was performed at 400oC and 5-60 min. Within the tested operation conditions, the reaction residence time of 15 min was the optimum to maximize the H2 yield. It was observed that using microemulsion technique increases the total gas yield significantly. Using microe...

Glucose is a 6-carbon carbohydrate compound present in plants and the ingredient for hemicellulose which makes up 30% of plants’ total mass. The current study uses glucose as reactant and evaluates hydrogen generation at different temperatures and different amounts of input flow of glucose – water mixture. Hydrothermal gasification method is used for hydrogen generation in an open system with c...
متن کاملThermoeconomic comparison between the performance of small-scale internal combustion engines and gas turbines integrated with a biomass gasifier
Recently, many countries have paid substantial attention to power generation from biomass gasification, particularly through small-scale plants. A number of power plant models have been suggested and analyzed; however, certainly, desirable configurations have not been identified yet. Moreover, their performances are ordinarily difficult to compare, especially owing to the fact that working ...
متن کاملCo-gasification of different rank coals with biomass and petroleum coke in a high-pressure reactor for H(2)-rich gas production.
Four coals of different rank were gasified, using a steam/oxygen mixture as gasifying agent, at atmospheric and elevated pressure in a fixed bed reactor fitted with a solids feeding system in continuous mode. Independently of coal rank, an increase in gasification pressure led to a decrease in H(2) + CO production and carbon conversion. Gasification of the different rank coals revealed that the...
