Pacific Northwest Laboratory (PNL) tested the catalytic gasification of bagasse for the production of methanol synthesis gas. The process uses steam, indirect heat, and a catalyst to produce synthesis gas in one step in fluidized bed gasifier. Both laboratory and process development scale (nominal 1 ton/day) gasifiers were used to test two different catalyst systems: (1) supported nickel
Theoretical calculations show that about 100 grams of hydrogen can be produced by one kilogram of bagasse. The hydrogen-rich gas produced from bagasse gasification, not only can be considered as an alternative energy source but also, hydrogen and synthesis gas produced in this process can be used in Oil, Gas and Petrochemical industries.
The highest production of syngas was obtained at points B of bagasse and sawdust (see Table 2). For bagasse and rice husk there are operating points in which the gas PCI is less than 4 MJ / Nm3, which limits its application for energy purposes. The syngas with the highest hydrogen composition were obtained at points A of bagasse and sawdust and the lowest at point B of rice husk.
Syngas from the PyroFlash or PyroGasification process is directly available as a product and it’s not used for heating the process as air is used for direct firing inside the reactor thus resulting in high quality syngas ranging its HHV between 5.4 MJ/kg to 6.7 MJ/kg. Using a gas generator, it can be transferred into heat and electricity. Both installations produce enough syngas to support
Syngas production from sugar cane bagasse in a circulating fluidized bed gasifier using 1095 Aspen PlusTM: Modelling and Simulation 2.2.1 Biomass Decomposition The biomass was specified as non-conventional stream and the ultimate and proximate analyses were inputted as well as the thermodynamic condition and mass flow rate. The yield reactor, RYIELD was used to simulate the decomposition of
To study the early formation of syngas production, the gas collection as a function of reaction time at 20, 30, 40, 50, and 60 min was done by carefully collecting the gas product in liquid storage (LS-01). After finding the optimum pyrolysis time condition, shown by the highest syngas product, two approaches were used to optimize the conversion process. The first approach was conducted by

used to develop a model for the gasiﬁcation of Sudanese sugar cane bagasse in a ﬂuidized bed reactor for syngas production. The developed model is based on Gibbs free energy minimization applying the non-stoichiometric equilibrium method for optimization of the gasiﬁer performance. The objective is to study the effect of important
Pyrolysis of bagasse followed by thermal cracking of tar was carried out at atmospheric pressure using a dual bed reactor. The first bed was used for the pyrolysis and the second bed was used for thermal cracking of tar. Iron fillings were used as the packed bed material in the second bed. The effects of reaction time (20 to 40 min), reactor temperature (600 to 900 °C) and packed bed height
1/1/2012 · The gasification of the sugar cane bagasse produces synthesis gas (syngas) in which CO and H 2 are the essential components. The composition of producer gas depends on the types of gasifier and the gasification conditions among others.
The objective of this work, therefore, is to provide a comparison between downdraft and fluidized bed gasification based on the production capacity of syngas using Aspen Plus simulation. The sugarcane bagasse used in the simulation was obtained from sugar factory PG Gempolkrep Mojokerto, East Java. The results show that at the ratio of steam to biomass equal 1.0, H 2 decreases with increasing
Experimental results showed that bagasse is an interesting fuel for syngas production via the gasification process, both from a gas composition and from a tar production point of view. Keywords: gasification, bagasse, tar, ceramic candles, high temperature. 1 Introduction More strict requirements to reduce the global CO2 emissions and the finite
Abstract Ethanol production by simultaneous saccharification and fermentation (SSF) using sugarcane bagasse as substrate was developed using batch and fed-batch mode. Acid, alkali, hydrothermal and hydrogen peroxide pretreatments to the sugarcane bagasse were tested. Experiments were carried out to optimize the enzyme load of cellulases and β -glucosidase. Four strains, two of Saccharomyces
15/9/2021 · Sugarcane (Saccharum officinarum) bagasse (SCB) is a biomass of agricultural waste obtained from sugarcane processing that has been found in abundance globally. Due to its abundance in nature, researchers have been harnessing this biomass for numerous applications such as in energy and environmental sustainability. However, before it could be optimally utilised, it has to be pre-treated using
It is estimated that in 2017 Brazil's abundant bagasse (sugarcane biowaste) could provide feedstock to nearly 300 SGT syngas plants and generate 14.5 billions gallons of fuel. The total biowaste from just corn and sugarcane in the Western Hemisphere and Asia would provide enough feedstock for 800 SGT syngas plants, which would produce 40 billion gallons of fuel.
