Waste Determination of platinum reforming catalysts ignition loss rate
1 Scope
This standard specifies the method for determination of petrochemical waste platinum reforming catalyst (platinum-tin catalyst) ignition loss rates.
This standard applies to the determination of petrochemical waste platinum reforming catalyst (platinum-tin catalyst) ignition loss rates. Measuring range. ≥0.50%.
2 Method summary
High temperature burning sample to calculate the sample according to the sample rate LOI losing quality.
3 Instruments and Materials
3.1 porcelain crucible (with lid). Specification 30mL.
3.2 crucible tongs.
3.3 dryer. Built valid silica gel desiccant.
3.4 Balance. accurate to 0.0001g.
3.5 box-type resistance furnace. capable of holding 820 ℃ ± 20 ℃.
Step 4 Analysis
4.1 Sample
Weigh 2.0g sample, accurate to 0.0001g.
4.2 Number of measurements
Independently measured twice and averaged.
4.3 Determination
4.3.1 The porcelain crucible and lid (3.1) in box-type resistance furnace, temperature controlled burning at 820 ℃ 30min. Remove coolish in a dry
Is (3.3), cooled to room temperature, weigh, to the nearest 0.0001g (m1), weighing is repeated to constant weight (mass difference of two weights ± 0.0005g).
4.3.2 added to the porcelain crucible 2.0g sample (4.1), stamped weighing, accurate to 0.0001g (m2).
4.3.3 The porcelain crucible lid partially open, placed in box-type resistance furnace (3.5), the control temperature at 820 ℃, burning 3h ± 0.5h.
4.3.4 Remove coolish, capped placed in a desiccator (3.3), cooled to room temperature and weigh to the nearest 0.0001g (m3). Repeat to
Constant weight.
