(Hong Kong, 7 March 2023) ? China Risun Group Limited (“China Risun”, or the “Group”, stock code: 1907), a leading global integrated coke, coking chemicals and refined chemicals producer and supplier and relevant operation management services provider in China, announced today that the 100kg-test coke oven* at its Sulawesi Production Base in Indonesia has begun operation as scheduled on 4 March 2023. The oven, which is part of the Risun Wei Shan coking chemical project with annual output capacity of 4.8 million tonnes, started production on the day after operating well-coordinated with quality, safety and progress meticulously controlled by participating personnel.

The Risun Wei Shan project under construction adopts the model of first operating the test coke oven, then the large coke oven, another example of the Group putting into actual practice the concept of R&D-first, followed by research and production integration. The approach helps lay the foundation for the project to raise coke quality and reduce coal blending costs, while serving as model for the coking industry of Indonesia to learn from in raising standard.

The 100kg-test coke oven employs more advanced technologies and boasts higher degree of automation, and the test data are closer to those of large coke ovens. The completion and commissioning of the 100kg-test coke oven apparatus can not only fully fulfill the coal blending experimental needs of Risun Wei Shan project, but also provide direct technical support for other related coking enterprises. It simulates the single-hole carbonization chamber of an industrial coke oven, uses [side-filling sample oven] and [single-side circular dual fire lanes] plus dual temperature measurement mode to achieve a uniform temperature field, high precision temperature control and coking results that correlate well with coke producing oven]. It also affords coke strength index of high intuitiveness and test results of high repeatability. It is another important R&D apparatus for coal blending innovation at the Group’s Sulawesi Production Base in Indonesia and also the first test coke oven of that scale in Indonesia.

In the future, the Group's production base in Sulawesi, Indonesia will focus on construction of the Risun Wei Shan project, to ensure it will be completed and in operation as planned within the year, and quickly meet production and efficiency targets. At the same time, with two test coke ovens operating, it can accumulate overseas coal research data and results to help build the Risun Wei Shan project into a world-class project and see the Group’s coking chemical production bases and coal blending and coking standard climb to matching international standards.

*For test only. The project will be equipped with large coke oven afterwards.
