Title
(EN) PRODUCTION METHOD FOR BRIQUETTE
(FR) PROCÉDÉ DE PRODUCTION DE BRIQUETTE
(JA) 成型炭の製造方法
Abstract
(EN)
Provided is a production method that is for a briquette and that comprises a step for obtaining a briquette having a water content of 5 wt% or less by molding a molding raw material containing a powder carbonized coal and a binder and drying the same at 60-100°C. The binder contains an aqueous solution of a polyvinyl alcohol having a saponification degree of more than 99.3 mol% and a polymerization degree of 1700 or more. The powder carbonized coal is a pulverized coal obtained by drying and carbonizing a coal including brown coal and/or subbituminous coal.

L'invention concerne un procédé de production d'une briquette comprenant une étape consistant à obtenir une briquette ayant une teneur en eau de 5 % en poids ou moins par moulage d'une matière première de moulage contenant un charbon carbonisé en poudre et un liant et le séchage de celle-ci à 60-100 °C. Le liant contient une solution aqueuse d'un alcool polyvinylique ayant un degré de saponification supérieur à 99,3 % en moles et un degré de polymérisation de 1700 ou plus. Le charbon carbonisé en poudre est un charbon pulvérisé obtenu par séchage et carbonisation d'un charbon comprenant du charbon brun et/ou du charbon sous-bitumineux.
(JA)
粉状の乾留炭とバインダとを含む成型原料を成型して60~100℃で乾燥し、水分が5重量%以下である成型炭を得る工程を有する成型炭の製造方法を提供する。バインダは、けん化度が99.3mol%を超え、重合度が1700以上であるポリビニルアルコールの水溶液を含有する。粉状の乾留炭は、褐炭及び亜瀝青炭の少なくとも一方を含む石炭を乾燥し乾留した微粉炭である。
