2023-5-18 Share:

Biomass chemical industry has made a significant breakthrough in the development of two key energy supply paths, namely petrochemical and coal chemical industries. Recently, the world's first million-ton "Shengquan Method" plant straw refining integration project (Phase I) has been fully operational in Daqing, Heilongjiang, a renowned oil city. This marks a new milestone for the advancement of biomass industrialization.

 

As the global leader in green and energy-efficient comprehensive utilization of biomass straw, Shengquan Group has invested over 2 billion yuan in constructing Phase I of this project. It is capable of processing 500,000 tons of straw annually to produce biomass resin carbon, hard carbon anode material, furfural, paper pulp, biological methanol, degradable materials and other eco-friendly bio-based products.

 

The "Shengquan Method" represents technological industrialization and paves the way for future utilization of straw.

The "Shengquan Method" biomass refining integration project is not only the culmination of Shengquan Group's more than four decades' experience in exploring green, low-carbon and high-quality recycling methods for agricultural straw but also an innovative achievement resulting from collaborative efforts with prestigious institutions such as Institute of Physics and Chemistry at Chinese Academy of Sciences, Wuhan University,Tianjin University,and Shandong University. The project holds independent intellectual property rights concerning key technology development process route design production equipment manufacturing as well as other industrial processes; it has accumulated 245 patents.

 

As a key project of Heilongjiang Province, this project has successfully overcome the global challenge of efficiently separating and utilizing cellulose, hemicellulose, and lignin in straw for high-value applications. By utilizing inexpensive plant straws such as corn straw, wheat straw, rice straw, and reed as raw materials, hundreds of products can be derived from comprehensive and sustainable utilization.

This project aims to revolutionize the traditional industrial chain and bring about significant changes in the industry.

The full operation of Shengquan Group's Daqing Project marks a successful transition from "technology" to "industry", which will profoundly disrupt the traditional industrial chain and fundamentally reshape the pattern of agricultural straw utilization.

 

Through the biological solvent method employed in the Daqing project, more than 45% pulp yield can be achieved from straw - surpassing that obtained through traditional processes. This not only resolves reliance on imported pulp but also addresses issues related to high sewage discharge and pollution associated with conventional papermaking methods. The environmental benefits are remarkable. Furthermore, process optimization innovation and energy-saving management enable carbon emission reduction by approximately 132,500 tons compared to traditional processes during the first phase of this project.

 

Through comprehensive utilization involving step-by-step separation and carbonization of three elements present in straw biomass resin carbon extraction process yields uniform particle size with high bulk density while maintaining low ash content. With a low calorific value exceeding 5000K/g., it can serve as a direct replacement for coal-based fuel combustion for power generation or further processed into hard carbon materials used in batteries or clean energy production like bio-methanol.

The biomass resin carbon possesses the dual characteristics of biomass and resin. Its preparation as a battery-grade hard carbon anode material exhibits high stability and consistency, with a carbonization rate exceeding 45%. Through collaborative research with Wuhan University, the gram capacity of the hard carbon has reached above 330mAh/g, achieving a first effect 90%, pole tablet compaction density 1.05, thereby overcoming existing industry bottlenecks. This material finds extensive applications in electric two-wheeled vehicles, A0/A00 class vehicles, energy storage batteries, and other fields due to its enormous market potential. As the flagship product of this Daqing project's production line, the annual output of biomass resin carbon can reach 160,000 tons directly contributing to the industrialization of sodium-ion batteries.

Bio-methanol, liquid ammonia, and natural gas produced using biomass resin carbon as raw materials are currently considered highly advantageous liquid fuels for achieving carbon neutrality at normal temperature and pressure conditions. Particularly in shipping applications, bio-based methanol serves as a relatively new clean alternative energy source for ships offering numerous advantages such as clean production methods, large-scale industrialization capabilities, high energy density levels along with convenient storage and transportation options. It will effectively contribute towards realizing early strategic goals of dual-carbon implementation across land transport systems as well as navigation and aviation industries.

Multiple process routes are progressing simultaneously while multiple downstream application directions exist. From one perspective, Daqing Shengquan project's large-scale production may potentially trigger significant changes within the value chain of new materials in future developments.

 

 

The practice of the new development concept and the creation of a novel development model are emphasized.

According to public data, China's annualstraw output is approximately 900 million tons, accounting for 20% to 30% of the global total. Among these, straw from food crops constitutes 89% of the overall amount.

 

In Shengquan's perspective, straw can be likened to oil and coal growing on the surface; if not utilized effectively, these abundant resources remain idle and wasted. In line with this vision, the No.1 Central document in 2023 proposed establishing and enhancing systems for collecting, utilizing, and treating agricultural waste such as straw, agricultural film, pesticide packaging waste, livestock manure, and poultry manure. Additionally, the Action Plan for Peaking Carbon before 2030 explicitly calls for expediting high-value utilization of straw while improving purchase procedures as well as storage and transportation systems; it also strictly prohibits burning.

Given the frequent release of policies related to this matter by authorities at various levels within China's government structure demonstrates their significant attention towards proper treatment of straw waste management practices.Currently in full production mode is Daqing Shengquan project which clearly signifies progress made in this process.

 

This project has enabled a remarkable transformation for small-scale straws - on one hand significantly enhancing carbon dioxide emission reduction efficiency by converting them into towering structures through their newfound role as "green biomass new materials" or sources of renewable energy; thereby promoting industrial transformation/upgrading efforts while safeguarding ecological integrity.

The economic benefits of rural revitalization, on the other hand, present a new starting point that offers farmers a fresh avenue for income generation. This in turn stimulates the growth of the straw procurement, processing, and transportation industry, resulting in the creation of nearly 10,000 job opportunities in Daqing and its surrounding areas. Consequently, this paves the way for agricultural recycling industrialization and economic development to flourish in Daqing.

This serves as a mere starting point. Shengquan Group is consistently augmenting its research and development investment, expanding the application scope of biomaterials and industrial chain layout, and continuously deepening the national strategy of high-quality economic development, green and low-carbon initiatives, as well as rural revitalization efforts.Not only does this play an exemplary role in the overall advancement of the biomass chemical industry but it also provides a novel model for sustainable development both domestically and internationally.

Based on Shengquan Group's industrial layout concept, we firmly believe that "Daqing model" incubation will persist in the field of comprehensive biomass utilization. A promising era of biomass resource exploitation lies ahead.
