This study investigates the combustion process of empty fruit bunches (EFB) and palm kernel shells (PKS) in a bubbly fluidized-bed combustion chamber. The biomass combustion simulation process uses a kinetic model consisting of chemical kinetic and hydrodynamic flow. This modelling is based on the two-phase theory in the fluidized bed. Where both phases in the bed are assumed that there are a mass and energy transfer between them. These phases include the emulsion phase and the bubble phase which contains solid particles. The constant temperatures throughout the reactor are assumed in this modelling. This study also investigates the parametric and effects of various parameters carried out. The experimental research shows that there is a change in bed diameter and has a negligible effect on combustion performance. The results of biomass combustion experiments with a fluidized-bed design have promising and satisfying results compared to several experimental studies in the literature. In addition, the increase in reactor temperature and a bed height of combustion efficiency also increased. However, the moisture of the biomass and the speed of the fuel entering can affect various for combustion efficiencies. Suitable operating conditions can produce maximum overall efficiency.

“…The structure of the product gas via gasification relies on the bed temperature of the reactor. Increasing the bed temperature in the gasifier increases the resultant heating value, the combustible gas content, hydrogen content and gas yield, however it would reduce the tar content dramatically [22].…”

“…Jin Woo Kook et al [22] reported that tar content can be reduced by several methods, either by increasing the temperature or change the feeding position. It was observed that increasing the temperature inside the gasifier from 720 °C to 825 °C increases the gas yield from 2.1 m3/kg to 2.7 m3/kg, as the carbon conversion of biomass increases [23].…”

Gasification is a thermo-chemical process used to convert biomass fuelsinto a fuel gas. Biomass gasification is considered amongst the best methods to enhance biomass-based energy production’s efficiency as it allows common biomass utilization.It has become more important as a mean of converting low energy-density such as biomass feeds or into a transportable high value gas for heat and power generation, chemicals and fuels. Operating conditions are affecting the gasification reactions. the review identified that in high-temperature gasification, endothermic reactions the secondary cracking and reforming of heavy hydrocarbons are favored and hence enhances the whole process’s efficiency. Finally, catalysts are vital for the biomass gasification process, and it is important to select the appropriate ones taking into consideration possible setbacks discussed above and will be explored further in this study.

Biomass conversion into solid, liquid and gaseous products by pyrolytic technology is one of the most promising alternative to convert the biomass into useful products and energy. The total characterization of the products from the pyrolysis of biomass is one of the great challenges in this field, mainly due to their molecular complexity. Pyrolysis is a process that causes degradation of biomass in a non-oxidative atmosphere, at relatively high temperatures, producing a solid residue rich in carbon and mineral matter, gases and bio-oil. The yield and properties of the products depend on the nature of the biomass and the type of the pyrolysis process (type of reactor, temperature, gas flow, catalyst). Due to the high molecular complexity of bio-oil, many different technical had been developed to their complete characterization. This chapter describes the principles of the techniques and main application of chromatographic methods (GC, LC, GC × GC, LC × LC, Nano-LC) in the analysis of bio-oils derived from thermo-degradation of biomasses. Especial attention is carried out to two-dimensional techniques that represent the state of the art in terms of separation, sensibility, selectivity and velocity of data acquisition for characterization of complex organic mixtures. For proper use of bio-oil in the chemical industry, it is essential the identification and unambiguous determination of its major constituents. Only then, it is possible to propose a recovery route of some of these components for the development of an industry dedicated to a bio-refinery. For this, chromatographic methods, especially GC × GC/MS, are fundamental because they allow analysis with high sensitivity and accuracy in identifying each constituent of the bio-oil.
