”Yao Yongkuan, the co president, said that after the launch of coke futures in 2011, its price discovery function played a positive role in guiding spot purchase, changing the previous environment of coal coke pricing lacking reference and opaque pricing. The company began to explore the procurement mode of the current linkage. With the gradual maturity of the derivatives operation of Nanjing Iron and Steel Group, it is one of the main varieties of furnace charge end hedging.
He said that at present, Nanjing Iron and Steel Group mainly uses coke futures to buy hedging on the cost side of lock price orders for forward delivery, so as to lock in processing profits. This model has become a normal hedging for Nanjing Iron and Steel Co., Ltd. to purchase coke, and a hedging process is initiated for qualified lock price orders. The hedging result is basically positive, managing price risk, improving customer stickiness and shaping enterprise competitiveness.
After 10 years of operation of futures instruments, Nanjing Iron and Steel Co., Ltd. has deeply realized the far-reaching significance of coke futures for the development of the industry. Yang Qing, General Manager of Galaxy Futures, told the reporter that for steel plants, the hedging of coke is more from the perspective of reducing procurement costs and coke inventory management. Especially after 2016, the spot price of coke was low and the price continued to rise. Some steel mills reduced the spot purchase price through panel purchase and achieved good hedging effect.
For example, when the price of raw materials rises, steel mills can buy coke hedging and make virtual inventory of coke through the futures market. When the coke rises to a high level, the futures price also rises. At this time, the steel plant can use hedging to make up for the loss caused by the rising coke purchase price. What the reporter deeply felt during the interview is that for the coal coke steel industry chain, as the traditional processing enterprises have a relatively fixed mode of procurement, processing and sales, they can obtain the average profit level of the industry as long as they operate normally in the past.
However, in recent years, after the baptism of big storms and waves in the market, the industry's profitability has fluctuated dramatically. Some steel and coking enterprises are on the edge of meager profits or even losses, and price fluctuations have had an impact on the survival of enterprises. Under this situation, using the futures market for hedging, with the goal of stable operation and hedging risks, industrial enterprises can no longer hesitate to swing, Instead, we should face up to the futures function and actively participate in the futures market to deal with risks.
"It is not easy for operators of coke enterprises to face up to and gradually participate in the use of futures to manage price risks, from the initial stage when we did not understand and dared not participate in futures." The relevant person in charge said that by participating in the futures market, we changed our business thinking, established our own futures team, took the initiative to understand the supply and demand situation of the industry, and refined the data, A rigorous price trend analysis system and futures hedging business system have been gradually formed.

In recent years, C9 petroleum resin has been widely used in paint, coating, adhesive and other industries, but the directly synthesized C9 petroleum resin has the disadvantage of poor color, which is difficult to meet the industrial use requirements. Catalytic hydrogenation is the main means of C9 petroleum resin modification at present. Hydrotalcite has become a molecular composite material with supramolecular structure due to its layered double hydroxides (LDHs) structure. In recent years, research on catalysts with hydrotalcite like structure has attracted much attention. This paper focuses on the preparation of nickel based catalyst with layered structure of hydrotalcite by coprecipitation and in-situ crystallization and its application in the catalytic hydrogenation modification of C9 petroleum resin. The effects of preparation and application conditions on the performance of C9 petroleum resin hydrogenation catalyst were systematically investigated by combining experimental evaluation with XRD, TPR, BET, SEM and other characterization methods. The experimental results of NiO/Al LDO catalyst prepared by coprecipitation method based on L_9 (3~4) orthogonal experimental design show that the significant factor affecting the preparation performance of the catalyst is the type of precipitant. The preparation conditions of the catalyst obtained are: ammonia as precipitant, the molar ratio of reactant to nickel salt is 3:1, the reaction temperature is 70 ℃
