Abstract: A process for producing liquid hydrocarbon products from a solid feedstock includes feeding the solid feedstock and hydrogen to a first stage hydropyrolysis reactor having one or more deoxygenation catalyst, and the solid feedstock includes biomass, waste plastic, or a combination thereof. The process also includes hydropyrolysing the solid feedstock in the first stage hydropyrolysis reactor to generate a process gas stream having partially deoxygenated hydropyrolysis product, H2O, H2, CO2, CO, C1-C3 gases, and char and catalyst fines and feeding the process gas stream to a solid separation system having a hot gas filtration unit having a plurality of filter elements that may separate the char and catalyst fines from the process gas to generate a vapour phase product and a dust filter cake.

Abstract: A system for hydroprocessing of a solid feedstock includes a solid feedstock feeding system disposed upstream from a hydropyrolysis reactor. The solid feedstock feeding system includes a piston feeder having an inlet, an outlet, at least one piston disposed between the inlet and the outlet, the at least one piston includes a chamber and a barrel disposed in and translocates within the chamber, the barrel includes a terminal end having a seal, and the seal includes an annular ring having a first wall and a second wall, the second wall is orthogonal to and extends from the first wall such that a first portion of the first wall protrudes away from the second wall in a first direction and a second portion of the first wall protrudes away from the second wall in a second direction.

Abstract: A piston having a chamber and a barrel disposed in and that may translocate within the chamber. The barrel includes a terminal end having a seal, and the seal has an annular ring having a first wall and a second wall, the second wall is orthogonal to and extends from the first wall such that a first portion of the first wall protrudes away from the second wall in a first direction and a second portion of the first wall protrudes away from the second wall in a second direction that is substantially opposite to the first direction.

Abstract: A residue stream comprising liquid hydrocarbons and metal-rich solid particles is reacted with an oxidant stream in a gasifier to produce a syngas stream that is quenched in a water bath. The risk of plugging in the water lines is reduced by removing solids from the recycled water streams. Acid gases are stripped from at least a portion of the recycled water to reduce the risk of precipitates forming from the reaction of dissolved acid gases with metal ions.

Abstract: The invention comprises a gasification reactor which comprises a vessel having at its upper end a downwardly directed burner and a combustion chamber located in the upper half of the vessel. The wall of the combustion chamber comprises an arrangement of interconnected parallel arranged tubes running from a common lower arranged distributor to a higher arranged common header. The distributor is connected to a cooling water supply conduit and the header is connected to a steam discharge conduit. Both the steam discharge conduit and the water supply conduit are fluidly connected to a steam drum. The steam drum is provided with a supply conduit for fresh water and the steam drum is positioned at a higher elevation than the common header.
