China Rare Earth Catalytic Materials Analysis prospects

Light rare earth lanthanum, cerium and praseodymium and other elements 4f electron shell has a unique structure , with good co- catalytic properties in a chemical reaction , so it is used as an excellent catalytic materials . Has entered the industrial production of rare earth catalytic materials , including rare earth catalytic molecular sieve materials, rare earth perovskite catalytic materials, and ceria-zirconia solid solution catalytic materials , mainly used in oil catalytic cracking (FCC catalyst ) , motor vehicle exhaust purification, industrial organic waste gas purification , catalytic combustion , and solid oxide fuel cells and so on . 2011 Chinese rare earth catalytic materials yield 29,200 tons, 4,380 tons of rare earth consumption ( Chinese Rare Earth Society estimates ) . We expect the Chinese government to strengthen environmental governance , especially for urban waste gas treatment , 2013 - 2015 rare earth catalytic materials market size is expected to maintain a 20% compound annual growth rate .

Since 2013 the eastern part of the north of Guangzhou -Shenzhen and other major cities in China continued to encounter fog and haze , increased vehicle exhaust emissions is an important factor . 2002 Chinese private car ownership 9,689,800 , 2012 has reached 88.386 million , 10 -year compound growth rate of 25 percent between . Rapid growth in private car ownership makes exhaust become the main source of air pollution in cities .

September 2013 the Chinese government issued a " Atmospheric Pollution Prevention Action Plan ," referring to moves to strengthen pollution control, strengthen motor vehicle environmental management: environmental protection and other agencies to strengthen environmental regulation of new production vehicles to crack down on the production and sale of environmental non-compliance of the vehicle violations ; strengthening the annual inspection of motor vehicles in use , for non-compliance of the vehicle shall not be granted environmental approval mark shall not be driven on the road ; encourage taxi to replace the exhaust gas purification device annually. United States, Japan and European countries through the implementation of stringent vehicle emissions standards to control exhaust pollution. China also began in 2000 on car exhaust emissions control ( I implement national standards ) , in 2011 began the implementation of the national IV standard ( equivalent to Euro IV). Ministry of Environmental Protection plans before the end of 2014 to implement national IV diesel vehicles are also standard , Beijing, Tianjin , the Yangtze River Delta and Pearl River Delta gasoline and diesel vehicles for the country to improve the standard V to 2017 extended to the whole country.

The main vehicle exhaust emissions of harmful ingredients include carbon monoxide (CO), hydrocarbons (HC) and nitrogen oxides (NOx) , etc. The main principle is to purify exhaust gas through the oxidation and reduction reactions to these contaminants into carbon dioxide , water and nitrogen harmless substances. The effect of exhaust gas purification catalyst is a key factor . Autocatalyst currently the most widely used of the three way catalyst (TWC), the structure of the active ingredients, carriers , adjuvants , and the coating composition, wherein the noble metals platinum (Pt), rhodium (Rh) and palladium (Pd ) is the most important component of the catalytic activity of rare earth ( mainly cerium, lanthanum and praseodymium ) role in the catalytic process from the series : replace part of the precious metal as an active ingredient to enhance the activity of the catalytic conversion of CO and HC ; vehicle exhaust Pb and S catalyst poisoning and thus prone to cause failure , after adding rare earth catalysts can improve the ability of anti-poisoning ; coating material used to prevent the carrier γ-Al2O3 into α-Al2O3 resulting in reduced surface area ; cerium oxide oxidation / price change by the reduction reaction of oxygen storage and release , better control of air-fuel ratio (A / F) and improvement of catalytic effect .

According to the Chinese domestic market size calculations catalyst , the rapid development of China 's auto market , rapid increases in the domestic market share of automobile exhaust catalysts and catalyst , such as updating the failure will promote the continued rapid growth in demand .

2014 / 2015 China passenger car production is expected to increase by 12 % and 10 %, respectively , heavy truck commercial vehicle growth 0% and 5 %, respectively. According to Wind statistics, the average displacement of 1.74 liters Chinese passenger car exhaust catalyst loading amount of experience with engine displacement ratio of 0.9:1 ( your research Platinum 2013 rights issue prospectus ) , the average per The catalyst to be 1.57 l passenger . Assuming commercial vehicle emissions an average of 5 liters, 4.5 liters of catalyst that is required per vehicle . 2013-2015 domestic market share is expected catalyst gradually increased from 20% to 30% ( previous market share in China autocatalysts basic occupied by Umicore , Johnson Matthey and BASF three international giants ) . Obtain new cars in 2014 and 2015 purification catalyst market will reach 12.896 million liters and 16,727,000 liters respectively .

In addition, with the growth of car ownership in China , the update will also increase demand for autocatalyst demand . "Atmospheric Pollution Prevention Action Plan ," stressed vehicle inspection strengthen environmental testing, to encourage taxi efficient exhaust gas purification device replaced annually . Assuming 2014 and 2015 , respectively, 1.5 % and 2 % of the car after the failure of the catalyst to be updated , which estimates the domestic car demand purification catalyst update was 1,336,000 liters and 2,468,000 liters . Overall, China in 2014 and 2015, domestic demand for automotive catalysts will reach 14.231 million liters and 19,195,000 liters , respectively, an increase of 39 % and 35 %.

Another major source of urban emissions of industrial production ( petrochemicals, paints and coatings , etc. ) toxic and harmful exhaust emissions , particularly volatile organic emissions (VOC). According to " China Rare Earth " reported ( RE purification catalysis applications -2009/01/16 ) , rare earth catalytic materials because of the unique nature of the catalytic oxidation , can in high concentrations of organic waste to purify the environment . In addition , rare earth better level structure and spectral characteristics can be mixed with nano- TiO2 photocatalytic when effectively improve the efficiency of catalysis at room temperature to eliminate CO, O3 and other harmful gases. China is still less current application of rare earth in the industrial waste gas , but the size of the U.S. market in 1997 has reached $ 1 billion . With the Chinese government is expected to gradually industrial emissions stringent requirements will drive demand for rare earths in the field of growth.

Application of rare earth catalytic material in the petrochemical industry (FCC catalyst ) is currently in the most used areas of rare earth catalytic materials, the global consumption of about 3-4 million tonnes of lanthanum oxide and cerium oxide annually. China 's large-scale enterprises, including FCC catalyst Catalyst Company , Sinopec , PetroChina Lanzhou catalytic Company , Leshan Run and rare earth catalyst , Inc. ( a subsidiary of Sheng and resources ), etc. According to the company the scale of the production line under construction , FCC catalyst production capacity of over 50,000 tons / year in 2015 , it is considered FCC capacity growth is expected to drive demand for rare earths continue to grow.
