Biomass resources
The constantly rising energy costs and how to efficiently utilize energy have led all industrial sectors to refocus their attention on the earliest actively utilized energy source by humans - biomass. Biomass is a widely distributed and resource rich renewable energy source, as well as an environmentally friendly low-carbon energy source. It has the advantage of net zero CO2 emissions and plays an important role in sustainable social and economic development. The use of renewable energy has become increasingly important, both in power generation and thermal processes. However, biomass also faces issues such as low energy density, difficulty in storage, and high transportation costs. To solve these problems, we conduct thermochemical conversion of biomass to turn it into solid, gas, and liquid products, which is more conducive to resource utilization.
Company is committed to environmental protection and environmental engineering industry, the technology research and development team of the international advanced technology digestion and re-innovation, cooperation with domestic and foreign equipment manufacturers, the formation of its own core equipment- Multiple Hearth Furnace (MHF). MHF is used in the comprehensive utilization of biomass resources, electronic waste pyrolysis and recycling, sludge pyrolysis and incineration, mineral roasting, activated carbon carbonization/activation, activated carbon regeneration, activated carbon application (biological fermentation product decolorization/ wastewater treatment, etc.) and other fields, master more than 30 corresponding patents, more than 80 sets of MHF engineering experience.
1. Biocoal
The torrefaction of biomass generates a high-grade biofuel – biocoal, which can replace coal in power and thermal production. Biomass torrefaction is the process of heating biomass to a temperature of 200-300 ℃ in an anaerobic environment. When biomass is heated at such a temperature, water evaporates and various low heat components (volatiles) contained in biomass are discharged. During this process, the main component of biomass is the decomposition of hemicellulose. This converts biomass from fibrous low-quality fuel to products with excellent fuel properties. Usually, the torrefaction process results in 20-30% mass loss (dry basis) and 10-15% energy loss.

2. Biomass pyrolysis/gasification
Under thermal action, organic matter in biomass is thermally decomposed into solid products such as biochar/gasification residue and gas products such as H2, CO, CO2, CH4, etc.
2.1 Preparation of Activated Carbon from Solid Products
The pyrolysis solid product biochar and gasification solid product gasification slag react with water vapor at high temperatures to form new pores, and the original pores are expanded to form activated carbon with high specific surface area and well-developed pores.
The yield of cashew shells was more than 10% and the iodine value was more than 1000 after carbonization and activation
After activation, the gasification slag has an activation yield of 30-40% and an iodine value of around 900
2.2 Preparation of Biomethanol/ Heat and Electricity from Gas Products
Introducing the concept of "one-time conversion", not solely for the purpose of producing methanol, combined with fuel production and energy supply, purified gas is directly catalyzed to synthesize methanol, and unreacted exhaust gas is combined with heating and power generation, significantly reducing production costs and improving overall efficiency.
