Design and development of biomass gasifier reactor to produce syngas
Problem that the study Address
Low electricity demand in rural areas due to low population density
Design
The design incorporates gasification technology to convert biomass into syngas for electricity generation.This technology can be utilized to convert oil palm waste, such as empty fruit bunches (EFB), into syngas, which can then be used as a clean fuel for electricity generation. It also mentioned the off-grid's application in designing gasifier reactor. The gasifier reactor should be designed to operate without the need for external electrical power, making it suitable for rural areas where electricity access is limited. The reactor should also incorporate features to minimize tar and impurities in the produced syngas. Efficient biomass preparation and feeding systems ensure consistent feedstock quality, while temperature control and monitoring systems optimize gasification performance. Gas cleaning and filtering systems remove impurities from the syngas, ensuring its quality for downstream applications. Overall, syngas produced from gasification can be used directly in combustion engines, turbines, or fuel cells to generate electricity. Designing efficient integration systems that connect the gasifier reactor with power generation units is essential for maximizing energy conversion efficiency.
Finding of their study
The study found that gasification technology effectively converts oil palm waste into syngas for electricity in rural areas. A self-sufficient gasifier design was developed, ensuring consistent feedstock quality and clean syngas. Integration with power generation enables electricity production, fostering sustainability in rural Indonesia.
Characterization of biochar from rice hulls and wood
chips produced in a top-lit updraft biomass gasifier
Problem that the study Address
Identify variations in chemical and physical properties of the biochar due to changes in the temperature distribution within the gasifier. Characterize rice hull and wood chips biochar produced in a top-lit
updraft gasifier.
Design
properties of biochar from top-lit updraft gasification and correlate such properties with the airflow rate and the utilization of insulation on the gasifier. were carried in a top-lit updraft gasifier with 10.1-cm internal diameter and 152-cm height. This gasifier was equipped with three thermocouples located at the top, middle and bottom; and a data logger (Onset® Model UX120-014M, USA) recorded the temperatures, as shown in Fig. 1. Two insulation conditions were used to produce biochar; no insulation and insulating the reactor with 88.9-mm of Fiberglass® insulation.
Finding of their study
it was found that the physical properties of the initial biomass played an important role in the final composition of biochar. For instance, the carbon content of biochar from rice hulls decreased from 40.9 to 27.2% as the airflow increased from 8 to 20 lpm when the reactor was insulated. In contrast, the carbon content of biochar from wood chips increased from 82% to 86% at the same conditions. Despite these variation in the carbon content, the BET surface area of biochar from rice hulls increased from 9.4 to 183 m2/g as increasing the airflow rate with insulation. Similarly, the BET surface of biochar from wood chips increased from 56 to 405 m2/g at the same conditions.
