Abstract: The invention provides an intelligent quantitative microscopic identification system for whole rock polished sections, which can greatly improve the collection efficiency of whole rock polished sections by adopting a microscopic collecting apparatus. In a preferable technical solution, the microscopic collecting apparatus is combined with the production line for the automatic preparation of whole rock polished sections to form an integrated system, which realizes an automatic solution from preparation to collection, therefore further improves the production and collection efficiency of whole rock polished sections, and which can cope with production, image collection and automatic scanning and splicing of mass whole rock polished sections, so it greatly improves the collection efficiency of the microscopic images of organic components for whole rock polished sections. People can collect 500 to 1000 sample pieces of whole rock polished sections in 12 hours by adopting the solution of the invention.

Abstract: A two-channel burner includes a pulverized coal supply mechanism, a transition channel, an inner secondary air guide tube, an outer secondary air guide tube, a combustion stabilizing chamber, and a flow smoothing chamber. The outer secondary air guide tube, the combustion stabilizing chamber, and the flow smoothing chamber are sequentially connected to form a burner body. The pulverized coal supply mechanism passes through an interior of the burner body. The transition channel is fitted over the pulverized coal supply mechanism. The inner secondary air guide tube is disposed between the transition channel and the outer secondary air guide tube and forms an inner secondary air passage together with the transition channel, and forms an outer secondary air passage together with the outer secondary air guide tube. An outlet end of the inner secondary air guide tube is formed to have a flared opening.

Abstract: A metal-zeolite composition comprising: (i) a zeolite phase; and (ii) a metal, other than aluminum or silicon, nanoscopically dispersed throughout said zeolite phase, wherein, if agglomerations of said metal are present, the agglomerations have a size of no more than 1 micron, wherein the zeolite may be, for example, a dealuminated zeolite, and the metal may be selected from transition metals, main group metals, and lanthanide metals. Also described herein is a method for producing the metal-zeolite composition in which a zeolite phase and metal salt are mixed and ground by a solvent-less ball milling process to produce an initial mixture, and calcining the initial mixture to produce the metal-zeolite composition. Further described herein is a method for converting an oxygen-containing organic species to a hydrocarbon, the method comprising contacting the species with the above described metal-loaded zeolite catalyst at a temperature of at least 100° C. and up to 550° C.
