Pd catalystとは 意味・読み方・使い方

A maldistribution part 3 having a Pd area 31 which is the outer peripheral part of this catalyst and in which Pd of high concentration is deposited and a Pt area 30 which is the inner peripheral part of the Pd area and in which Pt of high concentration is deposited is formed in this catalyst at least on the upstream side of exhaust gas.例文帳に追加

外周部にPdを高濃度担持したPd領域31と、Pd領域の内周部にPtを高濃度担持したPt領域30と、をもつ偏在部３を、少なくとも排ガス上流側に形成した。 - 特許庁

The front stage upper catalyst layer 3 bears Pd.例文帳に追加

前段上触媒層３は、Ｐｄを担持している。 - 特許庁

This reaction occurs in the low temperature of around 200 to 300°C, and NO_x is thereby stored in the Pd catalyst 1.例文帳に追加

この反応は約 200℃〜約 300℃の低温で生じ、これによりPd触媒１にNO_x が吸蔵される。 - 特許庁

To further enhance the oxidation activity of a saturated hydrocarbon of a catalyst having Pd supported thereon and to enhance even the high temperature durability of the catalyst.例文帳に追加
