DME synthesis technology exchange meeting held in May

At present, China has obtained a batch of dimethyl ether synthesis patented technologies and industrialization achievements with independent intellectual property rights and advanced world standards. In order to analyze and discuss the development trend of dimethyl ether synthesis technology, exchange and summarize successful experiences and issues, and further promote the domestic dimethyl ether synthesis technology innovation and large-scale promotion. China Petroleum and Chemical Industry Association is scheduled to be held from May 20 to May 22. Chengdu held the “2008 National Dimethyl Ether Synthesis Technology Exchange Seminar and Promotion Conference” to comprehensively promote the innovation of our country's dimethyl ether synthesis technology and the rational development of the DME industry.

The theme of the conference was the economics, scale and innovation of DME synthesis technology. Leaders and experts of relevant departments will interpret China's coal chemical industry policy at the meeting, analyze the status quo and trends of dimethyl ether industry development, and introduce the progress of alcohol fuels. The conference will also introduce new dimethyl ether synthesis reactors and industrial plant operation experience; exchange innovative technologies for dimethyl ether synthesis catalysts; discuss the feasibility of building a large-scale, cost-effective dimethyl ether synthesis project in China and a new reactor technology program.

Lifting Jack

Jack is one of the most simple lifting equipment with lifting height of less than 1 m, using jacking rigidity as a working device, through the top bracket or hold claw in the schedule at the bottom of the light and small lifting heavy lifting equipment.Divide into two kinds, mechanical and hydraulic jack is mainly used in mines, transportation and other departments as vehicle repair and other lifting, support, etc.The structure light and strong, flexible and reliable, one man can carry and operation.

Jack is divided into mechanical jacks and hydraulic jack, principle is different. In principle, the principle of hydraulic jack is based on PASCAL's principle, namely: the liquid pressure is the same everywhere, so, in a balanced system, the smaller piston top pressure is small, and the big pressure on the piston is bigger, it can keep the liquid stationary. Through liquid, so can be different on the different pressure, so that you can achieve the goal of a transformation.We are common to the hydraulic jack is to use the principle to achieve the force transfer.Mechanical jacks, using mechanical principle, in the past after pull (handle, claw namely rotary driving ratchet clearance, pull small bevel gear drive big bevel gear, make weight lifting screw rotation, so that the lifting socket for lifting or falling, and achieve the function of the lifting force. But not as easy hydraulic jack.
