Abstract
A reactor for accommodating high contaminant feedstocks includes a reactor vessel having an inlet for introducing a feedstock containing contaminants into an interior of the reactor vessel. A basket is located within the reactor vessel interior and contains a particulate material for removing contaminants from the feedstock to form a purified feedstock that is discharged to a purified feedstock outlet. A catalyst is located within the reactor vessel and in fluid communication with the purified feedstock outlet of the basket for contacting the purified feedstock to form a desired product.
Claims20
A reactor for accommodating high contaminant liquid feedstocks comprising:
- a reactor vessel having an inlet for introducing a liquid feedstock containing contaminants into an interior of the reactor vessel, the interior being defined by an interior wall of the reactor vessel;
- a liquid distributor assembly located below and in fluid communication with the inlet for discharging the liquid feedstock radially outward towards the interior walls of the reactor vessel;
- a basket located within the reactor vessel interior and below the liquid distributor assembly, the basket having a fluid permeable outer wall and a first fluid permeable inner wall that is spaced radially inward from the outer wall to define a first annular interior space of the basket, the first annular interior space of the basket containing a particulate material for removing contaminants from the liquid feedstock, the outer wall of the basket being spaced radially inward from the interior wall of the reactor vessel to define an annular flow space between the outer wall of the basket and the interior wall of the reactor vessel, and wherein liquid feedstocks introduced into the reactor vessel from the liquid distributor assembly flow through the annular flow space and radially inward through the first annular interior space of the basket and through the particulate material to facilitate removal of contaminants from the liquid feedstock to form a purified feedstock, the first fluid permeable inner wall forming a purified feedstock outlet of the basket and defining a central conduit that extends along the length of the basket, the central conduit having a conduit outlet for discharging the purified feedstock;
- and
- a catalyst that is located within the reactor vessel and in fluid communication with the purified feedstock outlet of the basket for contacting the purified feedstock to form a desired product.
A method of producing a product from high contaminant liquid feedstocks, the method comprising:
- introducing fluids comprising a liquid feedstock containing contaminants into a reactor, the reactor comprising:
- a reactor vessel having an inlet for introducing the liquid feedstock into an interior of the reactor vessel, the interior being defined by an interior wall of the reactor vessel;
- a liquid distributor assembly located below and in fluid communication with the inlet for discharging the liquid feedstock radially outward towards the interior walls of the reactor vessel;
- a basket located within the reactor vessel interior and below the distributor assembly, the basket having a fluid permeable outer wall and a first fluid permeable inner wall that is spaced radially inward from the outer wall to define a first annular interior space of the basket, the first annular interior space of the basket containing a particulate material for removing contaminants from the liquid feedstock, the outer wall of the basket being spaced radially inward from the interior wall of the reactor vessel to define an annular flow space between the outer wall of the basket and the interior wall of the reactor vessel, the first fluid permeable inner wall forming a purified feedstock outlet of the basket and defining a central conduit that extends along the length of the basket, the central conduit having a conduit outlet for discharging the purified feedstock;
- and
- a catalyst that is located within the reactor vessel and in fluid communication with the purified feedstock outlet of the basket for contacting the purified feedstock to form a desired product;
- and
- introducing the liquid feedstock into the inlet of the reactor vessel and allowing the feedstock to flow into and through the liquid distributor assembly, the liquid feedstock being discharged radially outward towards the interior walls of the reactor vessel and through the annular flow space wherein the liquid feedstock flows radially inward through the first annular interior space of the basket and through the particulate material so that contaminants are removed from the liquid feedstock to form a purified feedstock;
- and
- contacting the purified feedstock with the catalyst to form a desired product.
