fluidized bed gasifier (BFBG) for Empty Fruit Bunch (EFB) As expected, increasing the mass of bed particles from 0.05 briquettes gasification was proposed in this study. A to 1.5 kg led to increase in the bed pressure drop ΔPb but a combination of theoretical knowledge on fluidized beds and decrease in the distributor pressure drop ΔPd.

Effects of Purification on the Hydrogen Production in Biomass

produced compared to another oil palm wastes. Both of the fluidized bed gasifier and downdraft fixed bed gasifier models are developed in the Aspen Plus and the performance of the gasifier is determined by focusing on the total amount of hydrogen gas. Based on the gasification-purification simulation results obtained, the fluidized bed reactor

Experimental and Numerical Studies of Combustion

In this work, combustion characteristics in swirling fluidized bed gasifier using palm cake as feedstock was studied experimentally and numerically. A 3-D numerical model of reactor was created using ANSYS (Fluent) and was compared with experiment in the same scale. The diameter (D) was 0.20 m, and the reactor length was 1.50 m. The double air inlet pipe with an inner diameter of 46.8 mm was

Design of a Bubbling Fluidized Bed Gasifier for the

The fluidized bed gasifier (FBG) is considered the most suitable reactor for biomass gasification due excellent mixing, efficient heat temperature control and tolerance for fuels. Consequently, the proposed design of the bubbling fluidized bed gasifier for EFB briquette gasification will consist of three main parts; feeding zone, gasification


palm kernel shell and/or palm pressed fibre respectively. Bed was kept constant at 3 kg for the whole experiments. Two distinct types of bed arrangement i.e. layer and random mixture methods were applied. In layer mixture method, silica sand was placed at the bottom of the fluidization column and oil palm residue was poured unto it.


Operation. The KBR Transport Gasifier is a circulating fluidized-bed reactor which operates in either air or oxygen blown modes. The design is based on fluidized catalytic cracking (FCC) technology developed for refinery gasoline production in the 1940s. The gasifier consists of a mixing zone, riser, disengager, cyclone, standpipe, loopseal

Effects of Gasification Temperature and Equivalence Ratio on

to the desired gasification temperature. In this work, fluidized bed gasification is operated at three different temperatures (700, 800, 900°C) and three different ER (0.26, 0.3, 0.33). ER is used for studying the effects of gasifying agent. ER is defined as the ratio between amount of oxygen fed into the gasifier and stoichiometric

Air Gasification of Palm Empty Fruit Bunch in a Fluidized Bed

Nov 03, 2011 · In this work, gasification of palm empty fruit bunch as a potential lignocellulosic waste was investigated in a pilot scale air-blown fluidized bed. Silica sand and dolomite were used as bed material. The bed temperature was varied in the range of 650 to 1050 PPC.

Introduction Air-blown circulating fluidized bed (CFB) gasifiers have been in commercial use producing fuel gas for 02). In simple fuel gas applications with clean

Fluidized Bed Introduction - Washington University in St. Louis

Static Bed Height The transition velocity was almost independent of the static bed height, which varied from 0.4 to 1.0 m (Grace and Sun 1990). Similar results were reported by Cai (1989) and Satija and Fan (1985) with (Hmf/Dt) > 2. On the other hand, for a shallow fluidized bed of (Hmf/Dt) < 2 with Group B and D particles, Canada et

The main objective pursued in this work is to investigate the hydrogen production potential from agricultural wastes (coconut coir and palm kernel shell) by applying the air gasification technique. An experimental study was conducted using a bench-scale fluidized bed gasifier with 60 mm diameter and 425 mm height.

Progress in biomass gasification technique – With focus on

Sep 01, 2016 · The operating mechanism for a transport reactor gasifier is midway between a fluidized bed and an entrained bed gasifier . The schematic diagram of a transport reactor gasifier is shown in Fig. 6 . Transport reactor gasifiers normally operates at higher gas velocity (~15 m/s) which require smaller diameter of gasifier vessels so that all bed

circulating fluidized bed combustion applications (Lainhongshen et al, 2008). Biomass gasification in the gasifier is an intensive endothermic process. The bubbling and circulation of bed particles serves as a heat carrier, transferring heat from the densed fluidized bed to the freeboard zone inside the gasifier.
