专利汇可以提供Apparatus for continuous manufacture of furfural and acetic acid专利检索,专利查询,专利分析的服务。并且An apparatus for continuously producing furfural and acetic acid by thermodecomposition of ligneous and similar raw materials in the presence of the catalyst and in an inert atmosphere. A source of raw material is provided, a source of catalyst and a source of heated inert gaseous carrier. A drier is provided. Means are provided for conveying raw material and catalyst from the respective sources to the drier and for impregnating such raw material with the catalyst. Reactor means are provided and means for conveying impregnated raw material from the drier into the reactor means in a first direction. Pneumatic conveyor means conveys heated carrier from the respective source through and beyond the reactor means in a direction counter to the first direction so that the impregnated material yields distillate and solid particulate matter which is entrained by the carrier. Means are provided for separating the solid particulate matter from the carrier downstream of the reactor means. Condensor means separate distillate from the carrier downstream of the reactor means.,下面是Apparatus for continuous manufacture of furfural and acetic acid专利的具体信息内容。

  • 2. In an apparatus for continuous production of furfural and acetic acid by thermal decomposition of ligneous and similar raw materials in the presence of a catalyst and in an inert atmosphere, a source of raw material; a source of catalyst; a source of heated inert gaseous medium; a drier; means for impregnating said raw material with said catalyst; means for pneumatically conveying catalyst-impregnated raw material to said drier; reactor means having a perforate floor; means for conveying catalyst-impregnated dried raw material from said drier into said reactor means and for discharging it above said floor to form a bed thereon; pneumatic conveyor means for conveying heated inert gaseous medium from said source of heated inert gaseous medium from beneath said floor through said bed and beyond said reactor means in a direction counter to said first direction whereby said impregnated material yields vapor and solid particulate matter both of which are entrained by said heated inert gaseous medium; outlet means in said reactor means for enabling continuous removal of excess bed material; means for separating solid particulate matter from said heated inert gaseous medium and said vapor downstream of said reactor means; and condenser means for condensing vapor into a distillate from said heated inert gaseous medium downstream of said reactor means.
  • 3. In an apparatus as defined in claim 2, and further comprising washing means downstream of said condenser means for separating residual distillate from said inert gaseous medium.
