Detailed biomass conversion

Biomass, many people know the growth of natural substances, it is then stored by photosynthesis organic, inorganic substances. It can be broken down into biomass molecules, and then through a series of physical and chemical reactions, the energy released inside the biomass is absorbed and utilized by us.

The most common physical and chemical reactions through the cutting of biomass, extrusion, into a regular biomass particles. It can then be burned directly or decomposed with bacteria, microbes, enzymes, etc. to form gas, liquid, or solid fuel. For example, biomass biogas and ethanol production, including gasification, cogeneration, anaerobic digestion, pyrolysis and other processes.

gasification

Gasification is the process of converting carbonaceous material present in biomass into carbon monoxide and hydrogen by reacting the material with a controlled amount of oxygen or steam at elevated temperatures. The resulting gas mixture is called syngas or "syngas."

CHP

Combined heat and power (CHP), also known as cogeneration, , is a highly efficient, clean and reliable means of biomass power generation and thermal power generation. By installing cogeneration systems to meet the plant's thermal and electric infrastructure loads, combined heat and power can greatly improve the operational efficiency of facilities and reduce energy costs. At the same time, cogeneration reduces greenhouse gas emissions, which contributes to global climate change.

Anaerobic digestion

Anaerobic digestion is a series of processes by which microorganisms break down biodegradable materials under anaerobic conditions. It is widely used to treat wastewater sludge and organic waste because, in addition to producing biogas, it is possible to reduce the volume and quality of input materials.

Pyrolysis

Pyrolysis is a thermal decomposition process that occurs at moderate temperatures, has a high rate of heat transfer to the biomass particles, and has a short hot steam residence time in the reaction zone. The rapid pyrolysis of biomass produces liquid products, pyrolysis oil or bio-oil that can be easily stored and shipped.
