    Abstract: The disclosure discloses a catalyst capable of simultaneously removing COS and H2S in garbage gasification and a preparation method thereof, and belongs to the technical field of preparation of desulfurization catalysts. The method includes the following steps: pretreating an SBA-15 molecular sieve with a templating agent unremoved, which primarily includes the steps of removing the templating agent and introducing halogen atoms to modify the molecular sieve; then synthesizing an active component solution; and finally introducing active components into channels of the pretreated molecular sieve via surface tension by adopting an impregnation method, performing washing and drying, and performing calcining under an N2 atmosphere, so as to obtain the catalyst. An H2S and COS removal experiment is performed on the catalyst prepared according to the present disclosure under a simulated garbage gasification atmosphere, and a desulfurization experiment is performed as a control, so as to evaluate the desulfurization efficiency. The catalyst prepared according to the present disclosure can load the active components in fixed positions inside and outside the channels, and the components are easy to obtain, thereby having the advantages of low cost and good desulfurization effects.

    Abstract: Two photoelectric circuit sets each have a light source, two light switches, optical fibers, photoelectric sensor and computer. The light source emits visible light to the first switch, which is continuously deflected and reflected by a torsional micro-mirror. The light respectively irradiates each of the optical fibers in a composite material optical fiber prepreg layer. If the material is normal, the optical fiber is not damaged, the visible light passes through the optical fiber and irradiates the second switch, and is continuously deflected and reflected by a second torsional micro-mirror, the light irradiates the photoelectric sensor. The sensor outputs an electric signal to the computer. If the material is damaged, the optical fiber here is damaged, another corresponding optical fiber path at an intersection point is also damaged without electric signal output. The computer gives breaking position coordinates at the intersection point of two paths of optical fiber arrays.
