palladium based catalyst JL-H-12 for first-stage hydrogenation of pyroysis gasoline

JL-H-12 serials catalysts for first-stage hydrogenation of pyroysis gasoline, composed of noble metal palladium as active component and aluminum oxide as support with adding of various additives, were mainly used in the selective hydrogenation of pyroysis gasoline C6~C7, C6~C8, C5~C9, which were the cracking byproducts in the process of ethylene production.

In order to meet the market demand, JL-H-12, a new brand catalyst for the first-stage hydrogenation of pyroysis gasoline, was developed by Zibo Jiulong Chemical Co., Ltd. at the beginning of this century.JL-H-12 made greater improvement in water resistant, anti-arsenic, sulfur-tolerant and hydrogenation stability, etc. It was industrial applied successfully in the petrol devices of Yanshan Petrochemical, Shanghai Petrochemical, Lanzhou Petrochemical.

4. Comparative Evaluation of PGH-10A with competitive Catalyst

1000 h Comparative evaluation test of PGH-10A and competitive catalyst were carried in 100ml Insulation installation. The details were showed in following:

4.1 Evaluation Device

catalyst bed temperature of the evaluation device which was imported from Xytel companies USA was controlled in three sessions. The temperature difference of insulation bed reactor was < ±0.5 ℃ between inside and outside. Raw materials oil, hydrogen were injected into the pre-heater and mixted. when the temperature of the mixture reached the target temperature,operating parameters were tracking controlled automatically by a computer. The reaction products were isolated after condensation: oil was injected into the product tank, exhaust gas was emptied after measurement and the bromine number and diene value of oil were analysized.

4.2 Conditions of technological Evaluation

Operating pressure 2.8MPa
Inlet temperature 35~65℃
Liquid hourly space velocity 3.5h-1
Hydrogen-oil ratio 80:1(Vol)

4.3 Evaluation Materials

Raw materials oil was the whole distillate oil C5~C9 pyrolysis gasoline and its properties were showed in Table 3.

1000 h Comparative evaluation test of JL-H-12 and competitive catalyst were carried in 100ml Insulation installation. The result was showed in following:

Figure 1 Comparative evaluation results of the hydrogenation product diene value with time on stream catalyzed by JL-H-12 and competitive catalyst

1000 hours operation process(the diene value of raw materials was up to 42.53gI/100g and bromine number to 104.2gBr2/100g) indicated PGH-10A was adapted to low-grade oil and good hydrogenation performance and its catalytic activity was considerable to competitive catalyst in Figure 1. JL-H-12 has a good hydrogenation performance and stability.
