Title (EN) FILTRATION OF A COAL LIQUID SLURRY USING POLYISOBUTYLENE AND AN ALCOHOL
(FR) FILTRATION D"UNE BOUE LIQUIDE DE CHARBON PAR UTILISATION D"UN POLY-ISOBUTYLENE ET D"UN ALCOOL
Abstract: front page image
(EN)The rate of filtration of a coal liquid slurry is increased by adding polyisobutylene and an alcohol containing 2 to 10 carbon atoms to the slurry prior to filtration or by adding the alcohol to the slurry and washing a precoat cake of filter aid with an oil solution of polyisobutylene prior to filtration. Although the polyisobutylene and the alcohol each provides a filtration rate improving effect when used alone, a synergistic improvement in filtration rate is achieved by their combined use.
(FR)Le taux de filtration d"une boue liquide de charbon est augmente par addition d"un poly-isobutylene et d"un alcool contenant 2 a 10 atomes de carbone a la boue avant la filtration ou par addition de l"alcool a la boue et lavage d"un gateau de precouche d"aide de filtration avec une solution d"huile de poly-isobutylene avant la filtration. Bien que le poly-isobutylene et l"alcool aient chacun un effet d"amelioration de la vitesse de filtration lorsqu"ils sont utilises individuellement, une amelioration par synergie de la vitesse de filtration est obtenue en les combinant.
