摘要: A purification apparatus and purification method of a non-metallic semiconductor material relate to the field of preparation of high-purity materials, and are especially applicable to preparation of high-purity non-metal materials, in particular to an apparatus and method for purifying a non-metallic semiconductor material by means of a metal melt. The apparatus includes a furnace body, a pressure balance valve, a crucible disposed in the middle of the lower part of the furnace body, a heating and supporting structure for the crucible, a liftable injection mechanism disposed right above the crucible, and a liftable and rotatable recovery mechanism disposed next to the liftable injection mechanism. The method is completed based on the purification apparatus, and includes: injecting the gasified non-metal material into the metal melt under a high pressure environment; reducing the ambient pressure, and collecting the bubbles volatilized from the metal melt to obtain the purified non-metal material. The technical solution proposed in the present invention can be used to effectively remove impurities in the non-metal material, especially remove elements of similar properties. The apparatus is highly integrated and easy to control, and the method is simple.

摘要: A bottom fraction of a product of a hydrocatalytic reaction is gasified to generate hydrogen for use in further hydrocatalytic reactions. In one embodiment, an overhead fraction of the hydrocatalytic reaction is further processed to generate higher molecular weight compounds. In another embodiment, a product of the further processing is separated into a bottom fraction and an overhead fraction, where the bottom fraction is also gasified to generate hydrogen for use in further hydrocatalytic reactions.

摘要: The present disclosure provides a process for controlling syngas composition from an internal combustion engine-based syngas generator. While air is typically used as an oxidant, with nitrogen (N2) as a diluent, this results in expensive downstream compression, and low feedstock conversion efficiencies. This disclosure provides CO2 as a diluent to reduce N2 concentration in the syngas. In some embodiments, the CO2 diluent may be from either a biogas processing coupled with methanol, DME, and/or hydrocarbon production; or natural gas processing coupled with Fischer-Tropsch (FT) synthesis and/or other hydrocarbon synthesis.
