We have done a lot of development and experimental work in this area, and made great progress. We have
developed the vertical continuous production equipment for advanced carburant and process technology which is currently in a leading position at home and abroad.
Its main core technical features are:
1 The requirements for raw materials are not as strict as the traditional technical requirements. Ordinary medium
sulfur petroleum coke and even high sulfur petroleum coke can also be used as its main raw material. When use high sulfur petroleum coke as the raw material , equipment investment will be increased, production capacity decreased, and production costs increased including the consumption of productive raw materials,such as lime consumption, which is the raw material required for desulfurization, which is greatly increased in the case of high sulfur raw materials.
2 The production process is continuous and stable, unlike the intermittent production of traditional production process.
3 It is convenient and feasible for the discharge and collection of impurities in the production process, from the
original unorganized discharge to continuous and stable centralized discharge, which is convenient for collection and
treatment.
4 The waste heat can be fully utilized. The discharged flue gas can be used for waste heat power generation, and the
cooling water can be used for staff bathing and office heating and factory heating.
2.1,Storage and transfer equipment for raw materials and semi-finished products . Such as bucket elevator, horizontal
screw conveyor, belt conveyor, vibration feeder and vibration conveyor, wind conveyor, etc.
2.2,Calcination furnace:to complete the calcination process of petroleum coke, and its important task is to remove the
volatile matter in the raw materials. The calcination furnace adopts continuous discharge mode, which is characterized by energy saving and high efficiency. Raw materials is required to be 6000 tons / year.
2.3,Graphitization furnace: a new type of internal heated vertical continuous graphitization furnace is used in this
project to produce advanced carburant by using post-calcined petroleum coke. Its characteristics are: the strong dc current directly acts on the production raw materials, the use of its
own conductive resistance to make the material heating, so that its temperature quickly increased to the graphitization
temperature of nearly 3000 ºC, so as to generate graphite products.At the same time, volatiles, ash and other impurities are discharged under high temperature environment.
It is characterized by energy saving, high efficiency,environmental protection and high yield; The capacity of a
single furnace is about 10tons per day when the sulphur content of petroleum coke is 1%-3%. The capacity of a single furnace s about 6- 7tons per day or even lower when the sulphur content of petroleum coke is 7%-8%. The specific capacity is directly related to the sulfur content in raw materials.
Vertical continuous graphitization furnace is the core equipment of the project. The use of vertical continuous
graphitization furnace has the characteristics of power saving, small investment and convenient waste gas recovery.
2.4,Desulfurization device can be selected according to output and sulfur content in raw materials.
2.5,Cooling circulating water system.
2.6,Dust removal system: recycle the dust generated at each material transfer point during the production process and
improve the production and working environment.
2.7,Waste heat utilization part: this part is specially designed in combination with the utilization characteristics
of heat energy of the project investment unit.
