Bio-CHAR

Beijing Shengchang Green Energy Co., Ltd Pioneering Bio-CHAR Production

Beijing Shengchang Green Energy Co., Ltd, a subsidiary of Longji Energy Corporation, specializes in the production of high-quality bio-CHAR. Leveraging state-of-the-art technologies and processes, the company transforms locally sourced biomass feedstocks into a clean, renewable energy source that can be used for heating, power generation, and various industrial applications.

A Sustainable Solid Fuel Solution

Bio-CHAR is a carbon-rich, solid fuel produced through the process of pyrolysis, which involves heating biomass feedstocks, such as agricultural residues and forestry waste, in the absence of oxygen. This environmentally friendly fuel offers numerous benefits, including reduced greenhouse gas emissions, improved soil fertility, and enhanced energy security. With its high energy content and low environmental impact, bio-CHAR is an ideal alternative to traditional fossil fuels, aligning with the renewable energy sector’s commitment to sustainability and innovation.

The production of bio-CHAR is in line with Longji Energy Corporation’s mission to develop and implement innovative renewable energy technologies and processes that propel us towards a zero-emission future. By offering a sustainable alternative to fossil fuels, bio-CHAR production contributes to the reduction of greenhouse gas emissions, promotes energy security as well as helping to shift the local coal-dependency energy demand to a more environmentally friendly transition.

Bio-PELLETS

A 'Carbon-Neutral' Solid Fuel Solution

Bio-pellets, also known as biomass pellets or biofuel pellets, are a type of renewable energy source made from organic matter or waste. The organic materials used to make these pellets can include agricultural residues (such as straw and corn stover), wood waste (like sawdust and bark), and even organic municipal waste.

The environment-friendly merit of bio-pellets comes from their sustainable and carbon-neutral nature. They are considered sustainable because they are made from renewable organic materials, which are constantly being replenished through growth cycles. As these organic materials grow, they absorb carbon dioxide (CO2) from the atmosphere, a process that helps mitigate the effects of climate change.

When the bio-pellets are burned to produce heat or electricity, they release the CO2 that was absorbed during growth, resulting in a net-zero carbon emission, hence the term “carbon-neutral”.

Moreover, utilizing these materials for energy production reduces the amount of waste that ends up in landfills and decreases our reliance on fossil fuels. The production process of bio-pellets also requires less energy compared to the extraction and refinement of fossil fuels, leading to additional reductions in carbon emissions.

Bio-pellets offer a viable way to convert waste into energy, supporting the global transition towards more sustainable and environmentally friendly energy solutions.

Beijing Shengchang Green Energy Co., Ltd
Also Dominates the Bio-Pellets Production

As one of LONGJI ENERGY CORPORATION’s subsidiaries, Beijing Shengchang Yitai New Energy Technology Co., Ltd, established in 2012, specializes in biomass pellet fuel production from Beijing municipal horticultural residues (MHR), as well as the bio-char production to replace the residential coal consumption. Its pellet-making process can be exemplified as the following flow diagram:

The actual production line consists of the following pellet-making key components:

The production site’s annual utilization of MHR (municipal horticultural residues) is about 200,000 tons, it replaces around 63,000 tons of standard coal, which reduces about 163,000 tons of carbon dioxide emission annually. It has also contributed to the supply of bio-char and biomass pellets for more than 500,000 tons in Beijing alone. After years of unremitting efforts, it has grown into a large-scale biomass pellet fuel producer in northern China.

BIO-CHP

Bio-CHP is short for Biomass Combined Heat and Power Production.

The concept of CHP, also known as cogeneration, is a key aspect of the system’s efficiency. Its power and heat production can be exemplified as the following diagram:

One of LONGJI ENERGY CORPORATION’s subsidiaries, Inner Mongolia Hanglong Biomass Thermoelectric Co. Ltd., was established in 2017, operates a bio-CHP project that is categorized as a clean, renewable energy initiative. It’s specifically designed for comprehensive utilization of agricultural and forestry biomass resources as part of the national poverty alleviation initiatives. The company’s project has been named one of the “100 National Biomass CHP Demonstration Projects” by the Chinese National Development and Reform Commission.

The company’s establishment and operations efficiently, scientifically, and environmentally manage local agricultural and forestry residues. This not only relieves environmental stress in the area but also boosts local community’s income and employment rates, significantly supporting poverty alleviation policies and rural revitalization initiatives.

Hanglong Biomass Thermoelectric Co. Ltd. has been certified in quality, environmental, and occupational health and safety management systems. These certifications ensure high-standard and meticulous management of the company’s production operations. The company has forged long-term partnerships with universities, building a professional scientific research team. They hold 14 national patents and have been awarded municipal honorary flags.

LONGJI ENERGY CORPORATION, committed to actively exploring the comprehensive development and utilization of biomass energy. Centered around the established biomass combined heat and power projects, the company vigorously advances the construction of the “Biomass Energy Circular Industrial Park”. This involves the development of high-value biomass utilization, biogas, and organic fertilizer projects. The company is dedicated to creating a biomass circular and economic ecosystem to maximize the potential of biomass energy and ensure every part of the crop is utilized, thus boosting the wellbeing of the local communities.

Energy Efficiency Platform

Longji Energy Corporation demonstrates exceptional energy efficiency ingenuity through its commitment to developing cutting-edge, efficient, and reliable renewable energy solutions. By focusing on energy production process efficiency, ad-hoc improvisation, and up-to-date technology implementation, the company continually pushes the boundaries of what is possible in renewable energy development.

One prime example of Longji Energy Corporation’s ingenuity is the development of a Smart Energy Control Platform for bio-char, bio-pellet, and bio-CHP production. This innovative platform harnesses the power of Internet of Things (IoT) applications, cloud computing, and algorithmic engineering to monitor, analyze, and model energy production processes. By providing real-time insights into energy consumption and distribution, the Smart Energy Control Platform enables the company to optimize the efficiency and environmental performance of its renewable energy solutions. This platform was originally developed based on the blueprints of its bio-gas and the integrated fertilizer, cellulosic ethanol production plan:

To develop an integrated solution, the engineers reflected on the trials and errors made in these processes, actively monitored the system feedback on the biomass composites by critical process readings. For more complex and nuanced processes such as those in the biogas production, achieving the energy efficiency relies on operational feedback from the real-time monitoring of the product gas composition, the blockage condition, as well as the heat recovery and exchange effectiveness.

Then it has been implemented into other biomass energy productions. To ensure the energy conversion efficiency and equipment operation are at their optimal capacity in the combined power and heat production, the engineers have collected the data from every step of the processes such as the feeding system, boiler temperature control, heat and power generators, dust removal system.

Given the coal-dependent energy reality in the local settings, this system was also applied to blend biomass with traditional energy transition production.

The final integrated Smart Energy Control Platform utilizes cutting edge Internet and computational capabilities of Longji Energy Corporation to closely analyze the system data for personnel notification and to automate the production, the maturity of this systematic capacity can assist LEDI to better screen viable technological and processual solutions.
