摘要: A two or particularly three-phase process, and corresponding apparatus, desulfurizes sour hydrocarbon gas, e.g., natural gas, generally better than known, using a fixed-bed, two-phase processes in terms of the amount of H2S scavenged and the breakthrough time of H2S. The three-phase process is effective in scavenging H2S at ambient temperature and pressure, using a copper salt catalyst impregnated on alumina or other generally inert support, which is regenerable.

摘要: Disclosed herein is a mixed phosphate catalyst for converting lactic acid to acrylic acid, which is characterized by a high conversion of lactic acid, a high selectivity for acrylic acid, a high yield of acrylic acid, and correspondingly low selectivity and molar yields for undesired by-products. This is achieved with a particular class of catalysts defined by a mixture of metal-containing phosphate salts. Further, the catalyst is believed to be stable and active for lengthy periods heretofore unseen in the art for such dehydration processes.

摘要: A catalyst composition for preparing o-phenylphenol is provided. The catalyst composition includes a carrier; and a first active metal, a second active metal, and a catalytic promoter carried by the carrier. The first active metal is platinum, and the second active metal is selected from the first, second and third rows of transition metals of groups VIB and VIIIB. The present disclosure utilizes the carrier to carry the first active metal, the second active metal and the catalytic promoter so as to increase the selectivity of o-phenylphenol and the service life of a catalyst.

摘要: Processes, methods, and compositions for synthesizing carbon-based materials are provided. The method of synthesizing carbon-based materials includes providing precursors, forming carbon-encapsulated metal structures from the precursors, and forming nano-shell structure-based graphene materials from the carbon-encapsulated metal structures. The precursors are formed from a biomass and a catalyst, and may be pretreated prior to the forming of the carbon-encapsulated metal structures.
