Negro de humo de hornos
Spanish to English

Law: Taxation & Customs
Tariff lists
This appears in an alphabetical list with no further context. I suppose it's a shade, and thought it must be "smoke black", but I don't see where the "de hornos" bit fits in.
"Negro de acetileno.
Negro de humo de hornos.
Neopentilglicol."
"Negro de acetileno.
Negro de humo de hornos.
Neopentilglicol."

El negro de humo es otra materia petroquímica. Básicamente es carbón puro con una estructura muy semejante a la del grafito.
El tamaño de las partículas en el negro de humo es lo que determina su valor. Entre más pequeñas sean, más caro será el producto. Varían desde 10 hasta 500 mm (milésima parte de una micra que a su vez es la milésima parte de un milímetro).
Existen tres procesos generales para fabricar industrialmente el negro de humo, que son los siguientes; proceso de canal, proceso de horno y proceso térmico.

Furnace Black Process
This method forms carbon black by blowing petroleum oil or coal oil as raw material (feedstock oil) into high-temperature gases to combust them partially. This method is suitable for mass production due to its high yield, and allows wide control over its properties such as particle size or structure. This is currently the most common method used for manufacturing carbon black for various applications from rubber reinforcement to coloring.
Acetylene Black Process
This process obtains carbon black by thermally decomposing acetylene gas. It provides carbon black with higher structures and higher crystallinity, and is mainly used for electric conductive agents.

El negro de humo es un material inorgánico y coloidal producido por la combustión incompleta de gas natural gas u otros productos del petróleo. También se conoce como negro de hollín, negro de carbón, negro de acetileno, negro de lámpara, negro de horno, negro de canal, negro térmico o negro de gas dependiendo del proceso que lo produce. El negro de humo es fabricado por cierta forma de combustión que permite que la flama choque sobre una superficie fría, dejando un residuo negro. Este residuo se recolecta posteriormente como negro de carbón.

Carbon black is an inorganic, colloidal material produced by the incomplete combustion of natural gas or other petroleum products. It may also be known as lamp black, furnace black, acetylene black, channel black, thermal black or gas black depending on the process that produces it. Carbon black is manufactured by some form of combustion that allows the flame to impinge on a cool surface, leaving a black residue. This residue is then collected as carbon black.

Production
Two carbon black manufacturing processes (furnace black and thermal black) produce nearly all of the world's carbon blacks, with the furnace black process being the most common.

I always prefer to work with the Term Search, that way I find glossary entries, KudoZ, KOG and Wikiwords.
Anyway, it's your query and you're the boss ;-)

'Negro de humo de hornos' is 'furnace black'. The different types of black are substances that look like soot.
Carbon black (subtypes are acetylene black, channel black, furnace black, lamp black and thermal black) is a material produced by the incomplete combustion of heavy petroleum products such as FCC tar, coal tar, ethylene cracking tar, and a small amount from vegetable oil.
