Performance and Commercial Application of the Promoter LCC-A for Maximization of Propylene Yield

1 Introduction Propylene as an important feedstock for organic chemicals is mainly originated from steam cracking and catalytic cracking processes. During the FCC process the propylene content varies with the FCC catalyst and process technology adopted, resulting in significant difference in propylene concentration in the cracked product——LPG. The conventional FCC pro- cess generally gives a propylene yield of around 4%, while the FCC process with maximization of propylene yield can in…     

Study on Laboratory Method for Refining of SR Diesel Fuel

The method for refining the straight-run diesel fuel was studied in laboratory scale in order to make the acid number of diesel fraction comply with the standard while removing the naphthenic acids contained in diesel without causing environmental pollution. After comparing the effect of refining using three solvents, the isopropyl alcohol-HOA was specified as the best solvent. Meanwhile, the relationship between the acid number of diesel fraction and the amount of solvent used and the relationship between the concentration of solvent and temperature and the stability of diesel in terms of its acid number were also investigated. Experimental results had shown that when the mass fraction of the HOA-IPA solvent was 20% at a dosage of 17 mL of the solvent and a temperature of 30℃, the acid number of the refined diesel fraction was 0.015 mg KOH/g with a good stability of acidity in the diesel fraction,

Construction of One-Million-Ton-Class Ethylene Project Kicked off at Dushanzi

The construction of a 10-Mt/a oil refining and 1.0 Mt/a ethylene project at PetroChina Dushanzi Petrochemical Company （DPC） was kicked off in August 2005. This project includes 20 petroleum refining units and 12 chemical units with the budgeted investment amounting to 26.2 billion RMB. The construction of refining units is expected to be finished in 2007, while the construction of chemical units is slated for completion in 2008. After commissioning of the process units a production capacity of 5.5 Mt/a of finished petroleum products and 1.82 Mt/a of chemical products will be formed.
