Description
まず、図1を参照して、流動接触分解システム1の構成について説明する。流動接触分解システム1は、反応器10と、再生塔12と、磁気分離装置14とを備える。なお、図1中、原料油及びガソリンの流れは破線で表されており、FCC触媒の流れは実線で表されている。
ここで、本発明に係るFCC触媒の移送方法により、移送配管の摩耗が低減されることを確認するための試験を行った。試験としては、ASTM−C 704「Standard Test Method Abrasion Resistance of Refractory Materials atRoom Temperature」に準拠し、試験片20の耐摩耗性を測定した。具体的には、図3に示されるように、鉛直方向に対する傾斜角φ[°]の変更が可能な試験片20に向けて、この試験片20の上方に配置したノズル22から鉛直方向に沿ってSiC粒子を圧縮乾燥空気と共に噴射して、SiC粒子を試験片20に衝突させることで、試験片20の摩耗率[%]を算出した。試験条件は、
試験片20の材質:SUS−304BA及びSUS−316BAの二種類
試験片20の大きさ:100mm×100mm×2mm
圧縮乾燥空気の吹付圧力:0.01MPa〜0.5MPa
SiC粒子の噴射量:500g〜3kg
SiCの粒径:0.3mm〜0.85mm
噴射ノズル20の口径:4.74mm
噴射ノズル20と試験片20との直線距離:203mm
とした。なお、摩耗率は、試験前の試験片20の重量をW0[g]、試験後の試験片20の重量をW1[g]としたときに、(W0−W1)/W0×100にて算出した。
