編號(hào)為GB/T 34700-2017的“稀土型選擇性催化還原(SCR)脫硝催化劑”作為此批次唯一稀土相關(guān)國(guó)家標(biāo)準(zhǔn)位列其中，將于2018年5月1日起開始實(shí)施。
據(jù)了解，稀土型脫硝催化劑，不含釩，可替代釩鈦體系，且失效催化劑不屬于危險(xiǎn)廢物，無二次污染，可廣泛應(yīng)用于電力、水泥、冶金、陶瓷、化工、玻璃等行業(yè)。此次國(guó)家標(biāo)準(zhǔn)的即將實(shí)施，將為稀土脫硝催化劑的產(chǎn)品優(yōu)化和推廣發(fā)展提供一定的支撐作用，同時(shí)，將會(huì)成為大范圍推動(dòng)高豐度稀土的多元化、高價(jià)值化利用途徑之一。
