Talk:Hydrothermal liquefaction

Merge
I've been doing some web research in this area, and AFAICT, Thermal depolymerization is a less-used synonym for Hydrothermal liquefaction.

The only reference I can find is http://newoilresources.com/process.html which I don't think is notable, but the descriptions of the process are essentially the same - heat wet biomass to a high temperature, under pressure, such that the water is critical, for a relatively short period of time. --Chriswaterguy talk 05:17, 12 November 2013 (UTC)


 * Oppose: HL definition given involves "wet biomass". TD, while clearly related, can involve synthetic feedstock: note TD ref which lists e.g. "turkey offal, tires, plastic bottles, harbor-dredged muck, old computers, municipal garbage, cornstalks, paper-pulp effluent, infectious medical waste, oil-refinery residues" -- Limulus (talk) 18:49, 24 February 2014 (UTC)


 * Oppose: Not only do they not match inputs, but the processes seem to be somewhat different. There's not enough information on HTL to begin with.  This article should be filled out first. Martin Blank (talk) 20:15, 16 May 2014 (UTC)


 * Oppose: they are two different processes. Maybe they can be thought as synonyms in few cases, but they are different in general case. --Daniele Pugliesi (talk) 12:19, 14 May 2015 (UTC)

Catalytic Hydrothermal Reactor
I saw a company called Licella that has a factory process based around their "Catalytic Hydrothermal Reactor" (Cat-HTR) device that they are going to use in the UK for recycling plastics. They speak about it being new and revolutionary but then google and this artical seem to point to it instead being an evolution of HL. Should plastics as a feedstock be added to this artical or is what they are doing actually revolutionary Back ache (talk) 18:59, 6 March 2020 (UTC)

Merger proposal
Hydrous pyrolysis appears to be the same process. I suggest that the pages be merged. --Project Osprey (talk) 23:47, 26 April 2021 (UTC)
 * I went through all the refs on hydrous pyrolysis. Many are 404. There seems to be only one where 'hydrous pyrolysis' is mentioned. Multiple cites here use "hydrothermal liquefaction" in the title and spot checked a few to find it in the content. It really seems that "hydrothermal liquefaction" is more standard.Maneesh (talk) 20:57, 29 April 2021 (UTC)


 * Support merging Hydrous pyrolysis into Hydrothermal liquefaction. Hydrous pyrolysis is a bit of an oxymoron and to my knowledge is not a widespread term. While there is a lot of variability to what actual chemical processes these terms refer, I think these two are probably sufficiently closely related to be merged.
