Patent number: 9951278Abstract: Processes for controlling afterburn in a reheater and loss of entrained solid particles in reheater flue gas are provided. Carbonaceous biomass feedstock is pyrolyzed using a heat transfer medium forming pyrolysis products and a spent heat transfer medium comprising combustible solid particles. The spent heat transfer medium is introduced into a fluidizing dense bed. The combustible solid particles of the spent heat transfer medium are combusted forming combustion product flue gas in a dilute phase above the fluidizing dense bed. The combustion product flue gas comprises flue gas and solid particles entrained therein. The solid particles are separated from the combustion product flue gas to form separated solid particles. At least a portion of the separated solid particles are returned to the fluidizing dense bed.Type: GrantFiled: February 24, 2016Date of Patent: April 24, 2018Assignee: Ensyn Renewables, Inc.Inventors: Paul A.

Patent number: 9441887Abstract: Pyrolysis methods and apparatuses that allow effective heat removal, for example when necessary to achieve a desired throughput or process a desired type of biomass, are disclosed. According to representative methods, the use of a quench medium (e.g., water), either as a primary or a secondary type of heat removal, allows greater control of process temperatures, particularly in the reheater where char, as a solid byproduct of pyrolysis, is combusted. Quench medium may be distributed to one or more locations within the reheater vessel, such as above and/or within a dense phase bed of fluidized particles of a solid heat carrier (e.g., sand) to better control heat removal.Type: GrantFiled: February 22, 2011Date of Patent: September 13, 2016Assignee: Ensyn Renewables, Inc.Inventors: Sathit Kulprathipanja, Paolo Palmas, Daniel N Myers

Patent number: 9422478Abstract: Char-handling processes for controlling overall heat balance, ash accumulation, and afterburn in a reheater are provided. Carbonaceous biomass feedstock is pyrolyzed using a heat transfer medium forming pyrolysis products and a spent heat transfer medium. The spent heat transfer medium is separated into segregated char and char-depleted spent heat transfer medium. The char-depleted spent heat transfer medium is introduced into a dense bed of heat transfer medium fluidized by a stream of oxygen-containing regeneration gas. All or a portion of the segregated char is combusted in the dense bed using the stream of oxygen-containing regeneration gas. A portion of the segregated char may be exported out of the pyrolysis system to control the overall heat balance and ash accumulation.Type: GrantFiled: July 8, 2011Date of Patent: August 23, 2016Assignee: Ensyn Renewables, Inc.Inventors: Paolo Palmas, Paul A.

Patent number: 8961743Abstract: An improved rapid thermal conversion process for efficiently converting wood, other biomass materials, and other carbonaceous feedstock (including hydrocarbons) into high yields of valuable liquid product, e.g., bio-oil, on a large scale production, is disclosed. In the process, biomass material, e.g., wood, is fed to a conversion system where the biomass material is mixed with an upward stream of hot heat carriers, e.g., sand, that thermally convert the biomass into a hot vapor stream. The hot vapor stream is rapidly quenched with quench media in one or more condensing chambers located downstream of the conversion system. The rapid quenching condenses the vapor stream into liquid product, which is collected from the condensing chambers as a valuable liquid product.Type: GrantFiled: February 4, 2011Date of Patent: February 24, 2015Assignee: Ensyn Renewables, Inc.Inventor: Barry Freel
