peat wax[′pēt ‚waks] (materials) A hard, waxy material extracted from peat; it is similar to, and a substitute for, montan wax. Peat Wax a product obtained in the processing of peat tar. A distinction is made between crude peat wax, a dark brown to black pitchlike mass with a melting point of 50°–75°C; detarred peat wax; and refined peat wax. Most of the peat removed would be returned to the wetland once the resin and wax had been extracted. "The peat shrinks by about 10 per cent as a result of the resin and wax extraction process.
Plan to dig up ha of the Kaimaumau wetland to extract kauri resin and wax challenged. DOC joins opposition to Far North peat mining at Kaimaumau - NZ Herald New Zealand Herald. The extraction of coconut fiber from husks gives us this byproduct called coco-peat, which is a % natural growing medium. This cocopeat dried in the natural sun is processed to produce different items namely cocopeat block, coco peat briquettes, cocopeat tablets, etc. Loose coco peat is often referred as coco soil.
When first separated from petroleum, the lube oil fraction contains about % wax, depending on the source of the crude. Of course, in cold weather, a lubricating oil containing wax will solidify and prevent efficient engine lubrication. So the wax must be removed for the oil to work. One hundred years ago, wax was a nuisance and a by-product. The present study examined the modulatory effects of natural fiber substrates (agave fiber, coconut fiber and peat moss) and synthetic alternatives (capillary mat and cellulose sponge) on the nutritive and phytochemical composition of select microgreens species (coriander, kohlrabi and pak choi) grown in a controlled environment. Polyphenols were analyzed by UHPLC-Q-Orbitrap-HRMS, major.

The extraction and properties of crude peat wax were investigated. The composition of this wax obtained with various solvents was assessed in terms of the components: resin, asphalt, and wax.
It was concluded that extraction processes using benzene were likely to be of greatest value. Crude peat wax was further fractionated by chromatography to yield nine major by: 5.

The compositional profiles can be tuned by the manipulation of temperature and pressure and compared with the organic solvent extractions. Optimisation of. Procedures for extraction and purification of leaf wax biomarkers from peats J.E. Nichols Goddard Institute for Space Studies and Lamont-Doherty Earth Observatory, New York, USA In preparation for lipid extraction, peat samples must be freeze-dried.
Typically, lipids are extracted from lacustrine or marine sediments by. Peat: Industrial Chemistry and Technology explores the chemistry and chemical technology of peat as a chemical feedstock. The processes that generate peat chemicals, such as solvent extraction and acid hydrolysis, are discussed.
Some of the more important implications of peat use for humans and nature are also pointed out. This book describes alternative technologies for each of the major. These results indicate that extraction of peat waxes and production of high-energy peat fuels are compatible processes; although there is some loss of energy value after bitumen extraction, a benefit may be realized through the production of two products from the same feedstock.

SR/1. Oct EXECUTIVE SUMMARY. Peat deposits are common in Scotland and Northern Ireland and extraction for horticultural and fuel use, by a variety of methods, is concentrated in the Highlands and Islands of Scotland and in Northern Ireland.
The present invention relates to a method of extract composition control in peat extraction by carbon dioxide, in which method the extraction temperature is 5 - °C and pressure 70 - bar and the extraction is conducted in presence of a modifier.
The invention also relates to a peat extract comprising 1 - 60 w-% sterols and use of it in skin care or keratin fibre care products, general. An open trial with daily peat application showed benefit in patients suffering from chronic hand dermatitis and psoriasis palmaris.
Peat from the Altteicher Moor (Germany) was used as an adjunct to standard therapy [Figure 2]. Patients reported a more rapid relief from itch, inflammation was decreased and pustule formation was stopped earlier than usual.
Air-dried peats extracted with five different solvent systems yielded total bitumens of to wt.% of the dried peat and waxes ranging form to %. Hydrolysis and wet carbonization of peats prior to bitumen extraction resulted in yields which increased by factors of 2–3X.

The Act of is amended by the insertion of the following section: “82B. (1) In this section —. Peat Wax is a dark waxy substance extracted from peat using organic solvents.
It is very similar to the coal derived Montan wax and therefore has similar properties and uses. Raw peat wax is typically a mixture of three primary components, namely asphalt, resins and wax. Search the world's most comprehensive index of full-text books. My libraryMissing: extraction.

Nonetheless, the general reader will find some unfamiliar terms throughout the hook whieh are left undefined. The vagueness and subjectivity of some operational defini- tions further complicate assimilation and interpretation of the information presented.
Although Fuchsman strives to clarify the. the complex of processes carried out in working a peat deposit. In the excavation method, the raw peat is dug from an open pit, processed, and laid out to dry on a field in the form of strips.
In the milling method, the top layer of the peat bed is broken up to a depth of 8–25 mm. Peat bitumen obtained by solvent extraction of Irish high moor peat was subjected to chemical, structural and rheological characterisation.
The bitumen was fractionated on the basis of solubility in n‐heptane, toluene and ethyl acetate into wax, resin and asphaltene; each of these major constituent groups was further separated into sub‐fractions by column chromatography using solvents of.
