Continuous countercurrent extraction of hemicellulose from pretreated wood residues.
Two-stage dilute acid pretreatment followed by enzymatic cellulose hydrolysis is an effective method for obtaining high sugar yields from wood residues such as softwood forest thinnings. In the first-stage hydrolysis step, most of the hemicellulose is solubilized using relatively mild conditions. The soluble hemicellulosic sugars are recovered from the hydrolysate slurry by washing with water. ...
متن کاملRecycle Oil Pyrolysis and Extraction of Tar Sand
Western Research Institute is developing a new pyrolysis process called ROPE© (Recycle Oil Pyrolysis and Extraction) for recovering products from tar sands that require a minimum of upgrading to produce finished, marketable fuels or that can be used as a diluent to decrease the pour point of bitumen for transportation. The concept consists of two pyrolysis steps: (1) retorting tar sand at a low...
متن کاملCoal tars and coal tar pitches.
Numerous studies, mostly case reports, have found that occupational exposure to coal tars or coal-tar pitches (coal-tar distillates) is associated with skin cancer, including scrotal cancer; workers in these studies have included patent-fuel (coal-briquette) workers, pitch loaders, workers in electrical trades, and optical-lens polishers (IARC 1985, 1987). A 1946 study in the United Kingdom fou...
متن کاملExperimental Investigation of Phase Inversion of Liquid-Liquid Systems in a Spray Extraction Column
An experimental study of the phase inversion behavior of liquid-liquid dispersion has been conducted in a spray extraction column for systems of toluene / water, n-hexane/water, CCl4/water, toluene /water + glycerol (25 % wt), toluene + CCl4 (25 % wt) / water and toluene / acetic acid (5 % wt)/water. The effects of physical properties, mass transfer and column geometry...
