On October 18th, the Dalian Institute of Chemicals of the Chinese Academy of Sciences announced that it has signed a proprietary technology contract for the DMTO-II project and its supporting technology package (PDP) with the emerging company of Shaanxi Pucheng Clean Energy Chemical Co., Ltd. †This is the first foreign license of DMTO-II technology. This project is also the world’s first commercial demonstration device of DMTO-II technology.
Pucheng Clean Energy Chemical Co., Ltd. will use DMTO-II technology to build 1.8 million tons/year of methanol to 670,000 tons/year olefin project in Pucheng County, Weinan City, Shaanxi Province. The project will have an investment of about 15 billion yuan. It is expected to be completed and put into operation by the end of 2013. Project design has started.
According to the deputy director of Dalian Institute of Chemical Industry, Liu Zhongmin, in order to further enhance the economics of the process of methanol to olefins, DAL has begun to develop DMTO-II technology while developing DMTO technology. The DMTO-II technology uses the same catalyst to simultaneously achieve efficient conversion of methanol and C4+ to the target product olefins, and both reactions use a fluidized bed reaction process. According to the strong exothermic character of the methanol conversion reaction and the strong endothermic character of hydrocarbon catalytic cracking, the DMTO-II technology further improves the olefin selectivity; the strong endothermic reaction of C4 conversion is coupled with the strong exothermic reaction of methanol conversion and can achieve the heat Reasonable use; both reactions use fluidized bed reaction process and use the same catalyst, so that they can share the regenerator, simplify the system structure, and facilitate the upgrading of DMTO devices. Compared with traditional DMTO technology, DMTO-II technology uses more reasonable heat, yields higher olefins and reduces the methanol consumption per ton of olefin by more than 10%.
The DMTO-II technology was used for an industrial test with a methanol treatment capacity of 50 tons/day at the Shaanxi Coal Chemical Engineering Technology Center Co., Ltd. test site. From July 2009 to May 2010, the test device has undergone two phases, accumulatively completing over 800 hours of operational testing. The data show that the methanol conversion rate of the technology is 99.97%, the selectivity of ethylene + propylene is 85.68%, and the methanol consumption per ton of ethylene + propylene is 2.67 tons. The success of DMTO-II industrial tests laid the foundation for the construction of DMTO-II large-scale industrial production devices.
Deputy Director Liu Zhongmin told reporters that in order to ensure that China’s DMTO technology continues to maintain its leading position in the world, the Institute is currently planning to research and develop a new generation of methanol to olefin technology. The target is to achieve a single conversion of methanol 100%, ethylene + propylene selectivity Up to 85% to 90%, without the need for heavy product recovery of C4 or more, it is expected that industrial testing can be completed in about two years.

The valve is a series of gas emergency shut off solenoid valves, specially designed as gas pipe breaker for emergency use. It can be connected with gas leaking detection sensor, fire alarm circuit or other intelligent sensor modules so that on site or remote shut down on gas supply (manually or automatically) is possible, hence ensuring the safety on gas usage. The valve features an auto-close when strong vibration is detected. After close, manual operation is required to turn on the valve. This feature meets safety regulations in the event of an accident.
