Catalytic Reforming Catalyst For Removal Of Olefins In Reforming Aromatics

Description
RS-T-1-01 Catalysts for Removal of Olefins in Reforming Aromatics is the main replacement of activated clay employed in the pre-treatment equipments of PX process to remove the olefins from C8+ mixed aromatics. It is featured as wide operating temperature range, long life cycle and repeated regeneration capability.

1. Main Advantages of RS-T-1-01 Catalysts for Removal of Olefins in Reforming Aromatics
Due to frequent replacement, clay waste pollution, reduced clay resources and high security risks in frequent replacement, high activity Refining catalyst has become an inevitable choice to replace the conventional activated clay adsorbents.

Compared to the conventional activated clay adsorbents, RS-T-1-01 Refining catalyst has the following major advantages:
1.1 Longer cycle life
Under the same conditions of use, single cycle life is more than 8 times that of clay;

1.2 Wider temperature Range
RS-T-1-01 Refining catalyst can be activated at the temperature of 130 ℃.

1.3 Repeated regeneration
The catalyst can be used repeatedly by regeneration, thus the solid waste emissions will be reduced from 85% to 90%;

1.4 Decreased Bromine Index (BI)
The BI decrease can protect the subsequent equipments, and the extended operating cycle can reduce the frequency of maintenance.

2. RS-T-1-01 Refining Catalyst Specifications Descriptions
2.1 What’s RS-T-1-01 Refining Catalyst Appliance Principle?
The core active component of RS-T-1-01 is molecular sieve.

As with activated clay, molecular sieves Refining catalyst also adsorb the olefins with stronger polarity in reforming aromatics through porous material, so as to achieve the purpose of refining. However, molecular sieves have a longer operation cycle life than clay due to higher acid content, better acid distribution, and stronger and more stable acidity ; , meanwhile, due to their unique nature, sieves can be repeatedly regenerated.

2.2 The Main Physical Indexes of RS-T-1-01 Refining Catalyst
The Main Physical Indexes of RS-T-1-01 Refining Catalysts are listed as follows . They can also be customized.

3. Where Are RS-T-1-01 Refining Catalyst Applied?
   RS-T-1-01 is developed for PX front purification device, currently applicable to C8+ above feed refining process in the reforming tower bottom. Olefin and colloid content in feed have a great effect on single cycle life of Refining catalyst. Its applicable feed indicators are as follows:
   
   Table 3.1 indicators for reactor feed

Inlet temperature and bromine index affect single cycle life of Refining catalyst. Matching process should be paid attention to when used.

3.1 RS-T-1-01 Refining Catalyst Operating Conditions
According to RS-T-1-01 catalyst refining principle, temperature rising and pressure increasing benefit the operation, but in generalRS-T-1-01 catalyst become active at 130℃, in order to extend the life of Refining catalyst, operate at low temperature initially. Operating pressure requirements are similar to clay, but ensure the feed is in the liquid state, therefore the reaction pressure should be adjusted according to the catalyst operating temperature. The refining process recommends operating conditions to be at the maximum pressure the device allows, under high pressure, the single cycle life of the Refining catalyst can be appropriately extended.

3.2 Performance Guarantee
Oil Index after RS-T-1-01 Refining Catalyst Process as table below:

Table 2.4 Oil Index after RS-T-1-01 Refining Catalyst Process

According to preliminary tests, deactivated Refining catalyst can be reused after regeneration, with no significant decline in activity after regeneration, at the same time, according to the changes of physical indicators, we suggest that the frequency of regeneration can be more than 3 times.

4. Successful Cases
4.1 RS-T-1-01 Refining catalyst has achieved industrial applications in the 1 million tons / year PX devices of CNOOC Huizhou Refinery since November 2011, and has so far been running at low temperature. With conditions of feed Bromine index above 600 ~ 1900 mg Br/100g (an average of about 1200 mgBr/100g), Refining catalyst outlet Bromine Index is ≤ 20 mg Br/100g, xylene re-distillation tower top Bromine Index shows ≤ 1.0mgBr / 100g, other outlet indicators are basically the same as activated clay.

4.2 RS-T-1-01 is also widely used in China Petroleum & Chemical Corporation Shanghai Branch, China Petroleum & Chemical Corporation Tianjin Branch, China Petroleum & Chemical Corporation Jinling Branch, etc.
