This standard replaces the mandatory chemical industry standards HG3546-1989 "B110-2 Type-·Carbon Monoxide Medium Temperature Shift Catalyst", HG3547-1989 "B111 Type-·Carbon Monoxide Medium Temperature Shift Catalyst", HG35481989 "B112 Type-·Carbon Monoxide Medium Temperature Shift Catalyst", HC3549-1989 "B107, B107-1, B108, B109 Type-·Carbon Monoxide Medium Temperature Shift Catalyst" and HG2090-1991 "B113 Type-·Carbon Monoxide Medium Temperature Shift Catalyst". The main differences between this standard and HG3546~3549-1989 and HG2090-1991 are: the standard name is revised to "Carbon Monoxide High Temperature Shift Catalyst". The standard scope has been expanded to include B116, B117, B118 Type-·Carbon Monoxide High Temperature Shift Catalyst. - The content of "main physical properties and chemical longitudinal classification" in the technical requirements has been cancelled. - The radial crushing strength of particles has been renamed as the radial crushing force of particles and is measured according to HG/T2782--1996, and the corresponding technical index values have been adjusted.
The wear rate has been changed to be measured according to HIG/T2976-1999, and the corresponding technical index values have been adjusted. The content of the inspection rules has been modified.
This standard was proposed by the Policy and Regulations Department of the former State Administration of Petroleum and Chemical Industry. This standard is under the jurisdiction of the National Fertilizer Catalyst Standardization Technical Committee (CSBTS/TC105/SC1). The drafting unit of this standard is the South Chemical Group Research Institute, and the main drafters of this standard are Yi Shibin, Chen Xuemei, and Chen Yanhao. The previous versions of the standards replaced by this standard are: -HG3546-1989 (the original professional standard number is 2BG75006-1989); HG3547-1989 (the original professional standard number is ZBG75007--1989); HG3548.-1989 (the original professional standard number is ZBG75008--1989); HG3549-1989 (the original professional standard number is ZBG75009--1989) HG 2090-1991.

4 Test methods
4.1 Determination of activity
According to the provisions of Chapter 3 of HG/T3544, the determination of the activity of B113, B116, B117, and B118 catalysts is the same as that of B107, B107-1, B108, B109, B110-2, and B112 catalysts. 4.2 Determination of radial crushing resistance of particles
According to the provisions of HG/T2782, the range of the particle strength testing machine is 0N~500N, and the number of particles in the sample is 40. 4.3 Determination of abrasion rate
According to the provisions of HG/T2976, the sample preparation shall be placed in an oven and dried at (120±5)℃ for 2h. 4.4 Determination of loss on ignition
4.4.1 Preparation of samples
Mix the catalyst sample evenly, divide it into about 40 parts by quartering method, crush it all in a porcelain mortar, and then take about 20g by quartering method, and continue to grind it until it all passes through a 150μIH sample sieve (in accordance with the provisions of GB/T60031). Place it in a weighing bottle for use. 4.4.2 Determination steps
Weigh 1g~2g of sample (accurate to 0.0001g), place it in a porcelain crucible that has been calcined to constant weight at 600℃, and place the lid on the crucible obliquely. Place it in a high-temperature furnace and gradually heat it from low temperature to 600℃ and keep it for 2h. Take out the crucible, cool it slightly, put it in a dryer, cool it to room temperature and weigh it (accurate to 0.0001g). 4.4.3 Calculation of results
The ignition loss expressed as mass fraction u(%) is calculated according to formula (1): m--mz×100%
Where:
is the mass of the sample and crucible before calcination, in grams (g); - is the mass of the sample and crucible after calcination, in grams (g); - is the mass of the sample, in grams (g). The arithmetic mean of the results of two parallel determinations is taken as the determination result. 4.4.4 Allowable difference
The allowable absolute difference of the parallel determination results shall comply with the provisions of Table 2. Table 2 Allowable difference of loss on ignition

5.1. The quality of the product shall be inspected by the quality supervision and inspection department of the manufacturer. Products shall not be allowed to leave the factory without passing the inspection. Products leaving the factory shall be accompanied by a quality certificate, which includes the product name, model, batch number, production date, manufacturer name, product quality certificate, implementation standard number, etc. 2
HG3546-2002
5.2 Products shall be inspected in batches, and each batch shall not exceed 30t. An inspection batch may be composed of several production batches manufactured under the same conditions of materials, technology, equipment, etc., but the time for the next production batch to constitute an inspection batch shall not exceed two months. 5.3 The number of sampling units for products shall be determined in accordance with the provisions of CB/T6678 (see Table 3). Take out no less than 100mL of sample from each randomly selected sampling unit, and take out a total of about 3L of sample from each batch of products, mix them thoroughly, divide them into test samples and reserved samples by quartering, and seal them in sample bottles respectively. The sample bottles should be labeled with product name, model, batch number, lot size, sampling date, sampler, etc. The reserved samples should be kept for one year for inspection.

5.4 If any of the following indicators do not meet the requirements of Table 1 in the inspection results, re-sampling and re-inspection are allowed according to the provisions of 5.3. When the total number of packaging units does not exceed 22, the number of sampling units is the total number of packaging units. When the total number of packaging units is greater than 22, the number of sampling units is twice the number of corresponding sampling units in Table 3. If any of the indicators in the re-inspection results does not meet the requirements of Table 1, the batch of products shall be judged as unqualified products.
5.5 The purchaser shall have the right to inspect the products according to the test methods and inspection rules specified in this standard. When the supply and demand parties have disputes over product quality, they shall comply with the relevant provisions of the "Product Quality Arbitration Inspection and Quality Adjustment Management Measures". 5.6 Determine whether the inspection results comply with this standard according to the "rounded value comparison method" specified in GB/T1250. 6 Packaging, marking, storage, transportation
6.1 Products should be packaged in iron drums or plastic drums. A quality certificate should be attached, including product name, model, batch number, production period, manufacturer name, qualified poor stamp, etc. Pay attention to sealing and moisture-proof when packaging. 6.2 The packaging barrels should be clearly and firmly marked with the product name, model, trademark, net content, manufacturer name and address, and the "afraid of moisture" and "no rolling" signs specified in GB191. 6.3 The packaged products should be stored in a dry warehouse to prevent contamination and moisture. 6.4 It is strictly forbidden to drop, roll or hit during transportation and loading and unloading.
