catalytic

Under more strenuous conditions of temperature or catalyst the silanes bond chemically with the surface through siloxane linkage . 在加溫或催化劑的十分劇烈的條件下,硅烷通過硅氧烷鍵和表面化學結合起來。

The high production rate of modern reformers is due not only to good design but also to active and rugged catalyst . 現代化轉化爐產生高生產率,不僅因為設計良好,而且在于具有高活性和高強度的催化劑。

Catalyst returning to the reactor may not be completely regenerated because of insufficient time in the regenerator . 因為催化劑在再生器中停留時間不足,故返回反應器的催化劑可能未被完全再生。

The high production rate of modern reformers is due not only to good design but also to active and rugged catalyst . 生產率高的現代化轉化爐不只是由于好的設計而且在于高活性和高強度的催化劑。

Mechanical test results must be evaluated in conjunction with catalyst activity, selectivity, and stability data . 必須將機械測試結果和催化劑活性、選擇性和穩定性數據聯系起來進行綜合評價。

Impurities that promote deterioration of polymers can be foreign materials, such as residues from polymerization catalysts . 促使聚合物劣化的雜質可能是外加的物質,如殘存的聚合用催化劑。

The strength testing of extruded catalysts is complicated by three factors when compared to the testing ringformed catalysts . 擠條催化劑的強度測試與環狀催化劑相比,復雜的因素有三。

The explicitly stated reason for this study was to compare the quality of catalysts supplied from various manufacturers . 明確宣布這個研究是為了比較各個制造廠家生產的催化劑質量。

The physical resistance of catalysts plays a major role in catalyst selection and reactor design parameters . 催化劑的物理強度在催化劑選擇和反應器設計參數方面起著重要的作用。

In this manner a set of tests has evolved to the satisfaction of vendor and catalyst user for each catalyst . 用這種方式對每種催化劑建立一套催化劑賣主和用戶都滿意的測試方法。

We would like to measure the intrinsic selectivity behavior of a catalyst independent of any potential disguises . 我們很想去掉任何可能的假象以測定催化劑固有選擇性的可能。

In the thermal reactor it promotes corrosion, and in the catalystic reactor it tends to poison the catalyst . 在熱反應器中,它促進腐蝕,在催化反應器中,它能使催化劑中毒。

If the gas is processed in contact plants, this fluorine must be removed to prevent damage to the catalyst . 假若該氣體在接觸法工廠中加工,則氟必須除去,以免損害摧化劑。

A second more severe water test is to place the catalyst in boiling water and observe for any disintegration . 第二個更苛刻的泡水試驗是將催化劑放在開水中檢查有沒有開裂。

The swiss chemists think that the catalyst first draws the sensitizer to its surface and holds it there . 瑞士化學家認為,催化劑首先把敏化劑吸到它的表面并附著在那里。

On vaporization it reduces the bulk density of upflowing mixture and promotes the circulation of catalyst . 在汽化時使向上流動的混合物的松密度減少,并促使催化劑循環。

The setting of mechanical specifications for catalysts should take into consideration the needs of the user . 催化劑的機械測試技術規范的制定應考慮到用戶的需要。

For the catalyst producer, catalyst manufacturing cost and material limitations are paramount . 對于催化劑制造廠來說,催化劑生產成本和原料規格限定是最重要的。

In order to maintain the catalyst at a high level of activity the feedstock must be carefully purified . 為保持催化劑的高度靈活性,必須對進料精心加以凈化。
