Oxidative coupling of methane (OCM) is an economically valuable and promising reaction because it can directly convert the abundant feedstock natural gas into valuable C
2 hydrocarbons. The commercialization of OCM, however, is hampered by the low yield of C
2 products, which is associated with OCM reaction mechanism. It is generally accepted that traditional OCM reaction follows a heterogeneous-homogeneous mechanism, which consists of a heterogeneous activation of methane at the surface of catalysts to generate methyl radicals (CH

SHENYANG, April 17 (Xinhua) The Chinese Ministry of Public Security has passed an appraisal of a hand-held drug detector developed by researchers of the Chinese Academy of Sciences (CAS).
The device can give quick test results to identify morphine, methamphetamine and ketamine and assess the quantity.
Independently developed by scientists with the Dalian Institute of Chemical Physics affiliated to the CAS, the portable device is fitted with a small fluorescence detection module and uses a fluorescence labeling reagent to show the test results.
The device is able to detect as little as one nanogram of morphine in one milliliter of substance. It takes just over five minutes to analyze a sample, and the device has a 96 percent accuracy rate.

China’s Baofeng Soars on Plan to Build USD10.3 Billion Coal-to-Olefins Plant Tang Shihua China’s Baofeng Soars on Plan to Build USD10.3 Billion Coal-to-Olefins Plant
(Yicai Global) March 8 Shares in Baofeng Energy Group surged as much as 9 percent today after the coal chemical producer announced that it will invest CNY67.3 billion (USD10.3 billion) in a giant olefins factory, a substance used in the production of plastics, in the coal-rich Inner Mongolia Autonomous Region.
The firm’s stock price [SHA:600989] gained 1.43 percent today to close at CNY15.61 (USD2.40). Earlier in the day it had reached CNY16.83.
The Ordos-based plant, which should be up and running by late 2023, will have four olefin production lines, each with an annual output of one million tons, and five methanol production lines, with an output of 2.2 million tons a year each, the company said yesterday. It will use clean and efficient coal utilization technology developed by the Dalian Institute of C
