Definitions
- the present disclosure relates to a fluid catalytic cracking (FCC) process.
- FCC fluid catalytic cracking
- Propylene is an unsaturated organic compound having the chemical formula C33 ⁇ 4. It is the second most important starting product in the petrochemical industry after ethylene. It is used as a raw material for a wide variety of products. Nearly two-third of the demand for propylene is from plastic polypropylene manufacturers.
- Propylene is obtained as a component of natural gas during oil and gas extraction.
- propylene can also be produced by catalytic cracking of the leftover of vacuum distillation of crude oil, i.e. Vacuum Gas Oil (VGO).
- VGO Vacuum Gas Oil
- Other competing products obtained during the catalytic cracking of VGO include gaseous olefins, light cycle oil (LCO), gasoline and allied products.
- a fluid catalytic cracking (FCC) process comprises contacting a feedstock containing vacuum gas oil (VGO) with a catalyst composition in an FCC reactor at pre-determined conditions to obtain a resultant product comprising 7 % to 16 % propylene.
- the catalyst composition comprises an FCC catalyst and an additive.
- the present disclosure provides an FCC process using a catalyst composition resulting in a product having 7 % to 16 % propylene.
- the process includes the step of contacting a feedstock containing vacuum gas oil (VGO) with a catalyst composition in an FCC reactor at a pre-determined feed flow rate, a pre-determined weight hourly space velocity, a pre-determined temperature and a pre-determined pressure to obtain a product having 7 % to 16 % propylene.
- VGO vacuum gas oil
- the catalyst composition includes an FCC catalyst and an additive.
- the FCC catalyst is FCC-e-Cat.
- the ratio of the FCC catalyst to the additive is in the range of 90: 10 to 95:5, preferably, 93:7.
- the additive used in the catalyst composition comprises:
- the Group V element is phosphorus.
- the metal promoter is at least one element selected from the group consisting of magnesium, calcium, strontium, barium, copper, iron, nickel, zinc, gallium, indium, thallium and any of the lanthanide series metals.
- the metal promoter is at least one element selected from the group consisting of magnesium, calcium, strontium and barium.
- the metal promoter is a combination of zinc and gallium.
- the zeolite is at least one selected from the group consisting of ZSM-5, ZSM-11, ZSM-12, ZSM-48, ZSM-57, SAPO-5, SAPO-11, SAPO-17, SAPO-18, SAPO-34, SAPO-44, MCM- 22, an intergrowth of ZSM-11, zeolite Y and zeolite Beta.
- an excipient in a ratio of 1.1 to 2.5:1 with respect to the zeolite is also present in the catalyst composition of the present disclosure.
- the excipient in accordance with the present disclosure is at least one selected from the group consisting of a binder, a filler and a matrix.
- the binder is pseudoboehmite.
- the filler is alpha alumina. In an embodiment of the present disclosure, the matrix is silica.
- the process in accordance with the present disclosure is carried out in the temperature range of 500 °C to 550 °C and pressure range of 0.5 atm to 2 atm.
- An inert gas such as, nitrogen is used as a carrier gas.
- the feed flow rate is in the range of 5 ML/h to 7 ML/h and the weight hourly space velocity (WHSV) is in the range of 5.2 h "1 to 5.3 h "1 .
- WHSV weight hourly space velocity
- the ratio of the FCC catalyst to the additive is 93:7, from experiments 2 onwards. Experiments 2 to 6:
- ZSM-5 loaded with phosphorus along with metal promoters (Group II metals) magnesium, calcium, strontium and barium in varying amounts were used as the additive along with the FCC catalyst as given in Table-5 below.
- Five grams of dried zeolite was mixed with the solution of nitrate of metal promoter (magnesium, calcium, strontium and barium) and orthophosphoric acid.
- the slurry obtained was stirred at room temperature for 3 hours. After 3 hours, the slurry was evaporated in a rotary evaporator that was maintained at 75 °C under vacuum.
- the dried sample obtained was calcined at 550 °C for 5 hours.
- the calcined sample obtained was then ground into fine powder and sieved to obtain particles in size ranging from 600 ⁇ to 800 ⁇ . Thereafter, the fine powder was pressed into pellets and used along with the FCC catalyst, as the catalyst composition.
- the catalyst compositions of experiments 11 to 13 were prepared similarly as in experiments 7 to 10, except that instead of Group II metal salts, salts of nickel, iron and copper as the Metal Promoters were used, as given in Table-7 below.
- Cat/oil the catalyst to the feedstock weight ratio
