Apr 26, 2021 · Besides feedstock property and catalyst, the main operating parameters of DCC-I and DCC-II are reaction temperature, residence time, catalyst to oil ratio, and steam dilution. The reaction temperatures of DCC-I and DCC-II are around 560 ℃ and 530 ℃ respectively.

Jan 26, 2019 · Deep catalytic cracking (DCC) is a fluidized process for selectively cracking a wide variety of feedstocks to light olefins. Propylene yields over 24 wt% are achievable with paraffinic feeds. DCC uses a conventional traditional reactor/regenerator unit design with a catalyst that has physical properties similar to traditional FCC catalyst.

Deep catalytic cracking (DCC) is a commercially well-proven FCC process for cracking a wide range of hydrocarbon feedstocks, such as gasoils and paraffinic residues to propylene, butylenes, high-octane aromatic-rich gasoline, and ethylene.

Jun 11, 2018 · The DCC process selectively cracks a wide variety of feedstocks into light olefins, with a reactor/regenerator configuration similar to traditional fluid catalytic cracking (FCC) units (see figure).

Jan 11, 1998 · In May 1997, the Thai Petrochemical Industry Public Co. Ltd. (TPI) deep catalytic cracking (DCC) plant in Rayong started producing propylene, exceeding design values. DCC is now a mature, proven...

Jul 21, 2022 · Catalytic Cracking (Deep Catalytic Cracking, DCC for short) is a technology developed by Sinopec Petrochemical Research Institute (referred to as Petrochemical Research Institute) to maximize...

Nov 30, 2022 · DCC-pro (RTC) makes use of a new reactor design (Fig. 2) with: Higher catalyst concentration improving catalyst and oil molecular contact. Constant gas phase velocity ( v ), strenghthening diffusion and mass transfer, achieving stable fluidization state in the whole reactor.

Nov 30, 2022 · Deep Catalytic Cracking (DCC) process is very similar to conventional FCC process, but the operating condition of DCC process is regulated to realize deep cracking reactions, so the DCC unit has more severity on operating condition compared to that of …

Oct 28, 2022 · The new DCC reactor cyclone will allow IRPC to optimise the process of distillation of crude oil by transforming long residue - the remains resulting from the crude oil process - into propylene.

Nov 4, 2022 · The new DCC reactor cyclone unit is not only expected to revitalize the production of Propylene by crude oil distillation but is also anticipated to contribute to the production of a multitude of other value-added products.
