Comments[edit]

As a layperson, I can't yet understand the explanation given to distinguish NExBTL from biodiesel. For example links to an explanation of alkene.

I hope the author could more simply explain for us the basic process of making NExBTL and how it is different and how the end result is different from biodiesel.

In very simple terms, e.g. biodiesel, in my mind, takes a molecule of oil produced by plants, which is very long in comparison to diesel oil, and, using other chemicals, breaks it into shorter strands that makes molecules very similar to diesel (and some byproducts from the reaction). Could you make an explanation equally simple for NExBTL?

  • I understand that this is made without the transesterification step, but my biggest question is "what is the gel point", particularly compared with petrodiesel and biodiesel. Also, will it blend with either the two? Does it have the lube qualities that biodiesel has over petrodiesel? Article really needs some expanding. Pharmboy 16:44, 30 November 2007 (UTC)[reply]
    • Went and dug up the info on gel point/cloud point. If anyone has any data on use with traditional biodiesel to lower the cloud point when blended, I would love to hear it. That could fix one problem with biodiesel here in the US. Pharmboy 14:47, 1 December 2007 (UTC)[reply]

NExBTL is a pure hydrocarbon and as such does not contain oxygen. Biodiesel or FAME is an ester produced by reacting methanol with the veg oil (triglyceride). The cloud point of a molecule is determined by the length of the molecule and how many branches and double bonds it has.

Patents?[edit]

Vuo and others, it would be helpful to have some info on the patents involved, as I am assuming this is a patented process, whereby others can't duplicate this process with a license. I think that is necessary in an article like this, or if it isn't covered by patents, clarifying this would be helpful. I looked a little bit and didn't find enough info to be sure on this point. Pharmboy (talk) 20:07, 22 January 2008 (UTC)[reply]

It is most certainly propertiary process so it it extensively patented. Im pretty sure i spotted the right U.S patent from esp@cenet. If i understood the patent right it covers any means of converting feedstock containing more than 10% of fatty acids to diesel range hydrocarbon chains. —Preceding unsigned comment added by 88.114.30.102 (talk) 16:26, 1 February 2008 (UTC)[reply]

If anyone knows the patent numbers involved (US or otherwise), please list them. Patents are a matter of public record (by design!), and would serve as an ultimate reference to their process. --Mr z (talk) 05:01, 18 April 2015 (UTC)[reply]

Renewable diesel[edit]

I think that this process is one example of a relatively new category of processes for making "renewable diesel" (NOT biodiesel). I know of a least one other major effort which is a partnership between Cononco-Philips and Tyson Foods. If anyone knows about renewable diesel in general, we should also have an article on this. ike9898 (talk) 15:07, 20 February 2008 (UTC)[reply]

  • If anyone knows of another example of a company making renewable diesel, then we would have a reason for a separate article on Renewable diesel as well, since this is compatible with, but very different from biodiesel. PHARMBOY (TALK) 18:42, 20 February 2008 (UTC)[reply]
  • Other names for the same product are: HVO �Hydrotreated Vegetable Oil; Renewable Diesel; HDRD (Hydrogenation Derived Renewable Diesel) and NERD (non ester renewable diesel)

UOP, Conocco, BP, Nippon Oil, PetroBras, Eni, Galp, Syntroleum/Tyson all have announced at one time projects. Not many have gone ahead to investment decisions. SeveriG (talk) 11:55, 17 September 2008 (UTC)[reply]

Feedstocks[edit]

Is this the right place to discuss if or if not the government of Indonesia is corrupt? It bothers me that Wikipedia pages are used for political comment. —Preceding unsigned comment added by SeveriG (talk • contribs) 12:34, 20 August 2008 (UTC)[reply]

It is a part of Greenpeace's argument and contributes to the explanation of why the organization is attacking Neste. Its inclusion is not an indication that Wikipedia or its editors agree with the statement. The point of an encyclopedia is not to consists of an "unbroken wall" of officially true and politically correct statements, but to neutrally explain the motivations of involved parties. --Vuo (talk) 19:33, 20 August 2008 (UTC)[reply]

NExBTL → NEXBTL – Neste Oil has changed the name of the product family in 2014. 132.155.58.203 (talk) 07:04, 5 June 2014 (UTC)[reply]
