Strategic Perspective on the Promotion of Methanol Gasoline

Hu Qianlin, deputy secretary-general of the China Petroleum and Chemical Industry Federation: There has been some blindness in the development of coal chemical industry in some localities. To solve this problem, we must strictly implement the coal chemical industry policy that has been issued by the National Development and Reform Commission. And the adjustment of the petrochemical industry guidance. Methanol should strictly control the total production capacity, and vigorously eliminate backward production capacity; calcium carbide must strictly enforce the industry access conditions, the next 3 to 5 years can not be newly built projects to expand production capacity. On the other hand, we must actively develop downstream products Relieve overcapacity. Promoting methanol fuel for vehicles is a way to develop methanol downstream products. It is necessary to accelerate the implementation of the two national standards of "vehicle fuel methanol" and "vehicle methanol gasoline (M85)". Inner Mongolia is rich in methanol resources. There are no oil fields and large refineries in the region, and the development of methanol vehicle fuels is promising.
Liu Shengquan, director of the Xi'an Experimental Testing Center of the National Alcohol Ether Fuels and Motor Vehicles Committee, is a strategic resource. Oil is not a product you can buy, or you can buy it if you have money. It often involves politics. Deep economic and military issues. At present, most of China's imported oil is transported through the Straits of Malacca, where we have no control. If regional conflicts are encountered, transportation security will be difficult to guarantee. This large-scale military exercise in the United States and South Korea, the United States The three nuclear submarines sent were all deployed on this imported oil road in China. Therefore, we must stand at the height of national energy security and look at the promotion of methanol gasoline. Only in this way can we have more initiatives. When oil prices rise, we can reduce imports and substitute petroleum ether fuels for oil; when international oil prices decline, we can purchase large quantities of oil and do a good job of strategic oil reserves.

The deputy secretary-general of the National Alcohol Ether Fuels and Motor Vehicles Committee, Fallen Lian: Alcohol ether fuel is the most feasible and most realistic choice for the transition from traditional energy sources to new energy sources. It fully embodies the national conditions based on coal. Alcohol ether fuels Relevant disputes have long existed and have not emerged recently. Therefore, the relevant law enforcement agencies can not just “fire brigade” and have problems to investigate. In fact, the standards for DME cooking stoves, storage tanks and other systems are The preparation, but because of the first standard, that is, the national standards for product applications have not yet come out, so the relevant standards will not be introduced. Therefore, the relevant functional departments should objectively identify the controversial issues. "Car methanol The submission of the national standard for gasoline (M15) has been completed and will be reported to the National Standards Committee after discussion by experts. Currently, companies in Shanxi, Shaanxi, Sichuan, Ningxia, Gansu and Inner Mongolia are discussing the establishment of 6 provinces and districts of coal-based alcohol ether fuels. Test demonstration area issues, through the joint promotion of methanol gasoline.

Zhou Xiujie, an energy industry researcher at China Investment Advisors Co., Ltd.: The advantages of methanol-gasoline are obvious, and it has been used in Shanxi for nearly 10 years. The pilot project in Zhejiang has also achieved initial results, but the national standard for the use of methanol-gasoline has not yet been introduced. The use of methanol gasoline is more prudent.

First of all, methanol gasoline has a corrosive effect on the engine and its components. American automakers such as GM, Ford, and Chrysler clearly stated in the user manual that damage to vehicles using methanol gasoline is not covered by the warranty. To promote methanol gasoline in China , put forward higher requirements for automotive metal materials and rubber materials.

Secondly, methanol is easy to delaminate with water, so when using methanol gasoline, the requirements for the sealing of vehicle fuel tanks, oil pipelines and other equipment are relatively high, and the waterproof work of methanol gasoline during storage and transportation must also be implemented.

Once again, methanol is a toxic substance that can cause harm to the human body if used carelessly. This requires the production, transportation, and sale of methanol gasoline to operate strictly in accordance with safety regulations.

Finally, in terms of market sales, with the exception of Shanxi, Sinopec, and CNPC, which jointly sell methanol gasoline, the sales channels for methanol in Quzhou, Zhejiang Province are limited. Only six private gas stations sell methanol gasoline. Visible, methanol gasoline is still in the cracks to survive The sales channel needs to be broadened. Methanol gasoline as a clean energy still needs the government to provide support in marketing. At the same time, the standard of methanol gasoline should be unified as soon as possible nationwide. Otherwise, vehicles using methanol gasoline can only be in this province. Driving inside, out of the province may be oil-free.

Cut Anchor

Functionally, there is no difference between a cut thread and a rolled thread. The difference enters in the manufacture of the bolt. Using 1" anchor bolts as an example the processes are:

Cut thread is created by a process that cuts away the steel from the round bar to form the threads. To cut thread, the process begins with a full 1" diameter round bar. The threads are cut into the round bar resulting in an anchor bolt with 1" diameter threads and a body of 1" diameter.

Rolled thread is created by a process that extrudes steel from the surface of the round bar to form the threads. To roll thread, the process begins with .912" round bar. The round bar is rolled through a set of dies that displace the steel to form the threads. The result is a bolt with 1" diameter thread and a .912" body.

Cut thread meets all ASTM specifications. Rolled thread meets ASTM specifications with the exception of A325 and A490. However, one thing to remember is that Architects and Engineers often specify cut thread for anchor bolts. Cut thread can usually be substituted for rolled thread but the opposite may not always be true.
