Process for converting biomass into flammable gases

Biomass gasification is the pyrolysis of organic components in biomass to produce combustible gases under high temperature. The whole process can be divided into drying, pyrolysis, collection and purification.




1. Drying process

After the biomass enters the gasifier, the moisture in the biomass is released by heating. The main drying stage is during 100~120℃.


2. Pyrolysis reaction

When the temperature rises above 250℃, the pyrolysis reaction begins. About 70% of the volatile components can be released from biomass during 300-400 ℃, while the coal will release about 30% of the volatile components when the temperature reach 800℃. The volatile components of the pyrolysis reaction mainly includes steam, hydrogen, carbon monoxide, methane, tar and other hydrocarbons.


The advantage of LCDRI:


The quality requirements of the domestic internal combustion engine are as follows:

1. Impurity particle size ≤ 5 μm

2. Moisture content ≤ 40mg/Nm³

3. Impurity content ≤ 30mg/Nm³

4. Gas temperature ≤ 40℃

5. Tar content ≤ 50mg/Nm³

6. Gas calorific value ≥ 4MJ/Nm³


LCDRi can guarantee the converted gas quality requirements are as follows:

1. Impurity granularity ≤ 5 μm

2. Water content  ≤ 10mg/Nm³

3. The content of the impurities ≤ 10mg/Nm³

4. The gas temperature ≤ 40℃

5. The tar content ≤ 10mg/Nm³

6. The calorific value of the gas ≥4.2MJ/Nm³


The above figures are far more than the domestic requirements, and the quality requirements of the gas can be improved effectively.
