In 2011, global demand for platinum and palladium inautocatalyst applications increased by 4.4% and 5.2%respectively. These gains lifted autocatalyst consumptionof platinum to a total of 3.02M ounces (94.0 tonnes) lastyear, with palladium reaching a ten year high of 5.53M ounces (172.0 tonnes). While palladium has staged animpressive recovery since the auto industry recession of2009 (with demand now well in excess of pre-recession levels), platinum’s situation remains problematic. Although demand for platinum has improved considerably from its low of 2.52M ounces (78.3 tonnes) in 2009, last year’s total of 3.0M ounces (94.0 tonnes) remains well adrift of the record high 4.01M ounces (124.8 tonnes) which platinum enjoyed in 2007 prior to the economic downturn.
2011年，全球鉑、鈀催化劑需求分別增加了4.4%和5.2%，使去年鉑催化劑總消耗量達(dá)到302萬(wàn)盎司（約94噸），而鈀催化劑消耗量達(dá)到553萬(wàn)盎司（172噸），創(chuàng)10年歷史新高。自2009年汽車(chē)行業(yè)衰退以來(lái)，鈀催化劑的需求有了顯著回升（目前需求量已超過(guò)經(jīng)濟(jì)衰退前的水平），但鉑催化劑的狀況仍不容樂(lè)觀。和2009年252萬(wàn)盎司（78.3噸）鉑催化劑總消耗量相比，去年300萬(wàn)盎司的總消耗量確實(shí)有了大幅上漲，但與2007年經(jīng)濟(jì)危機(jī)之前歷史最高的401萬(wàn)盎司（124.8噸）相比，仍存在較大差距。
In the main, platinum’s difficulties in autocatalyst can be ascribed to two main factors, both of which relate to light vehicle applications and in particular, light duty diesels. First, notwithstanding the growing importance of the heavy duty sector, light duty diesels account for two-thirds of global platinum autocatalyst demand, with the vast majority of this being concentrated in Europe where diesel’s share of light vehicle production is disproportionately large. While light diesel production globally has re-attained pre-recession levels, this is not entirely the case in Europe where leading edge emission standards and generally higher PGM loadings apply. Meanwhile, diesel’s share of light vehicle production elsewhere in the world remains moderate and although production gains have occurred in recent years, these have been concentrated in areas where emissions regulation is weaker, with correspondingly lower PGM loadings.

總體而言，造成鉑催化劑市場(chǎng)困境的原因可以歸結(jié)為兩個(gè)方面，并且這兩個(gè)方面均與輕型汽車(chē)應(yīng)用，尤其是輕型柴油汽車(chē)有關(guān)。首先，雖然重型汽車(chē)的重要性日益凸顯，但輕型柴油汽車(chē)卻占全球鉑催化劑需求的三分之二，其中大部分集中在歐洲。歐洲輕型柴油汽車(chē)在輕型汽車(chē)產(chǎn)量中的比例偏高，且超出正常比例。雖然全球輕型柴油汽車(chē)產(chǎn)量已經(jīng)恢復(fù)到經(jīng)濟(jì)危機(jī)之前的水平，但歐洲市場(chǎng)卻并未完全恢復(fù)，因?yàn)闅W洲采取了最為嚴(yán)格的排放標(biāo)準(zhǔn)和更高的PMG載量要求。此外，世界其他地區(qū)柴油汽車(chē)在輕型車(chē)產(chǎn)量中的比例保持穩(wěn)定，雖然近幾年柴油汽車(chē)產(chǎn)量增加，但增長(zhǎng)主要集中在排放監(jiān)管較為薄弱，PGM載量相對(duì)較低的地區(qū)。
