Patent number: 11639477Abstract: A gasification process may include (a) introducing a liquid hydrocarbon feedstock and at least one of a dry feedstock or a first slurried feedstock into a reactor lower section, wherein the at least one dry feedstock or first slurried feedstock is introduced through two primary feed nozzles while the liquid hydrocarbon feedstock is introduced through at least two secondary feed nozzles; (b) partially combusting the feedstocks in the reactor lower section with a gas stream comprising an oxygen-containing gas or steam to evolve heat and form products comprising hot synthesis gas; (c) passing said hot synthesis gas from step (b) upward into a reactor upper section; (d) and introducing a second slurried feedstock into said reactor upper section, whereby heat from said hot synthesis gas supports reaction of the second slurried feedstock by pyrolysis and gasification reactions.Type: GrantFiled: August 9, 2021Date of Patent: May 2, 2023Assignee: LUMMUS TECHNOLOGY, LLCInventors: Chancelor L. Williams, Albert C. Tsang, Philip Rodney Amick, Jayesh Shah, Paul Edgar Michaud, Shrinivas Lokare

Patent number: 9611437Abstract: The present disclosure relates generally to a method for obtaining synthesis gas from a gasifier that has a low methane content. The synthesis gas is obtained as an extraction gas from the quench section of the gasifier, and can be utilized as feedstock for a variety of chemical production processes without the need for expensive pre-treatment to remove methane.Type: GrantFiled: January 5, 2011Date of Patent: April 4, 2017Assignee: Lummus Technology Inc.Inventors: Shuncheng Ji, Chancelor L. Williams, Ron W. Herbanek

Patent number: 9567538Abstract: Improved two-stage entrained-flow gasification systems and processes that reduce the cost and complexity of the design and increase the reliability, while maintaining the efficiency by implementing a first chemical quench followed by a second water quench of the produced syngas. The quenched syngas is maintained above the condensation temperature of at least one condensable component of the syngas, allowing residual particulates to be removed by dry particulate filtration.Type: GrantFiled: June 26, 2013Date of Patent: February 14, 2017Assignee: Lummus Technology Inc.Inventors: Clifton G. Keeler, Chancelor L. Williams, Ivan O. Bustamante

Patent number: 8888876Abstract: The present invention relates to a system and process for gasifying feedstock such as carbonaceous materials. The invention includes partial combustion of dry solids and pyrolysis of carbonaceous material slurry in two separate reactor sections and produce mixture products comprising synthesis gas. The invention employs one or more catalytic or sorbent bed for removing tar from the synthesis gas. The inventive system and process allow a gasification to be carried out under higher slurry feeding rate and lower temperature with the provision to manage the tar being produced, therefore to increase the conversion efficiency of the overall gasification.Type: GrantFiled: May 8, 2013Date of Patent: November 18, 2014Assignee: Lummus Technology Inc.Inventors: Albert C.
