What is gasification of biomass?
By applying heat, solid biomass or other carbonaceous substances can be gasified to create a synthetic fuel that burns like natural gas. Almost any dry organic material can be gasified to create a clean-burning fuel that, in most situations, can replace fossil fuels.
Gasification transforms common “waste” materials into a flexible gaseous fuel that you may use to power your internal combustion engine, stove, furnace, or flamethrower whether you start with wood chips, walnut shells, construction trash, or agricultural waste.
How does gasification work?
A waste-to-energy technology is gasification. Syngas is produced by converting waste materials into heat, oxygen, and pressure. Since the late 1700s, when it was employed to make tar, gasification has existed in some form. The technology has evolved into what we now refer to as “advanced gasification” over the past 20 years.
What is “advanced gasification”?
Advanced gasification is the thermochemical creation of synthesis gas, sometimes known as “syngas,” from waste materials (carbon-based compounds). In contrast to incineration, gasification involves the conversion of the fuel to a gas (and byproducts like ash and charcoal) at high temperatures (a broader waste-to-energy technology that burns waste materials in the presence of open oxygen). The initial gas is subsequently refined to produce a “pure” syngas, which can then be converted with high conversion efficiency into a useful energy source.
What makes up the “advanced gasification” energy?
1. Electricity—using a steam cycle or a gas engine.
- Steam or heating for industrial or commercial processes.
- Liquid biofuels produced through the liquefaction of Fischer-Tropsch gas.
- Bio-SNG can replace diesel or gasoline in vehicles on the road, rail, in the air, and on the water. Bio-SNG has a significantly lower carbon footprint than petroleum-based goods.
- Synthetic Natural Gas (SNG), which can be directly injected into the network of natural gas pipelines after being produced through the methanation process.
- Hydrogen, which is obtained from the syngas once its hydrogen content has been extracted and purified.What are the applications of “advanced gasification”?
A wide range of useful outputs, including power, heat, liquid biofuels, synthetic natural gas, biosynthetic natural gas, charcoal, and hydrogen, can be produced via advanced gasification.
This implies that electricity and heat can be used to run nearby plants or sold to the community’s energy grid. Particularly beneficial as renewable alternatives to fossil fuel energy are liquid biofuels and green hydrogen.
Advanced gasification technology from Haiqi is perfect for plants of any size, from 1MWe to 25MWe, because it can be deployed in modules. The plant’s carbon footprint can be decreased by building it close to the source of the garbage being treated thanks to the modular installation. Plants can be scaled up as needed thanks to modular installation.
What types of materials can be gasified?
A wide range of organic, biodegradable materials can be gasified. As Haiqi notes, the method is now most frequently utilized to convert biomass feedstocks like wood chips. However, it can genuinely treat carbonaceous waste, including so-called municipal solid trash, from a significant amount of waste.
6.plastics – “because they are high in carbon”
Waste materials such as metal and glass cannot be aerated. However, most of the content of municipal solid waste contains “carbonaceous” material and therefore can be. Haiqi’s continuous testing has proven that our gasification technology can generate energy from nearly 60 different raw materials, including：
- Nut shells
- Rice straw
- Grape bagasse
- wood chips
- Pine cones
- Demolition rubble
- Municipal Solid Waste (MSW) – also known as Refuse Derived Fuel (RDF) after recycling
Some of these feedstocks need to be treated before biomass gasification, e.g. drying, pelletizing. Our technology is very versatile for different feedstocks, but when a gasification plant specializes in one or two feedstocks, we certainly like it because it will be more efficient.
