Multi-adaptive fast loading attached air-cooled dust removal equipment is disclosed. The equipment is mainly composed of five parts: a spindle clamping mechanism, a link mechanism, a bearing connecting mechanism, an axial telescopic mechanism and a dust treatment mechanism. The equipment is connected with a tool holder through an axial connecting mechanism and installed on a machine tool. The axial telescopic mechanism forms a cavity with a processing surface, the gas flow generated by a negative pressure vacuum cleaner forms negative pressure in the cavity, and the telescopic mechanism is fixed to a machine tool spindle housing through the link mechanism to prevent the rotation of the spindle from driving the equipment to rotate and interfere with a workpiece, finally realizing rapid collection and treatment of chips.

A catalyst for the desulfurization and deodorization of gasoline, which is expressed by the formula: QBH[AMO], where: Q denotes a quaternary ammonium cation consisting of RRRRN, in which R, R, R, and Reach denotes independently a Cto Csaturated alkyl group, respectively, provided that at least one of R, R, R, and Rdenotes a Cto Csaturated alkyl group; B denotes a metal cation of Naor/and K; H denotes a hydrogen atom; A denotes a central atom of B, P, As, Si or Al; M denotes a coordinated atom of W or Mo; O denotes an oxygen atom; 1&#x2266;l&#x2266;10, 0&#x2266;m&#x2266;3, 0&#x2266;n&#x2266;3, l+m+n&#x2266;14, x=1 or 2, 9&#x2266;y&#x2266;18, 34&#x2266;z&#x2266;62, and l, m, n, y and z all are integers. A method of the desulfurization and deodorization of gasoline by using the catalyst comprises the steps of: mixing the catalyst and an aqueous solution of hydrogen peroxide, and then adding the gasoline to react them with stirring under conditions of 25 to 90&#xb0; C. and 0.1 to 1 MPa for 10 to 180 min. An odorless gasoline can be obtained through settlement or centrifugation, and the catalyst is recovered.
