摘要:
The present invention provides a process for producing chlorine by the catalytic gas phase oxidation of hydrogen chloride with oxygen, wherein the reaction is performed on at least two catalyst beds under adiabatic conditions, as well as a reactor system for performing the process.
摘要:
The present invention relates to a process comprising the steps a) synthesis of carbon nanotubes, b) optional inerting and c) cooling of the product. The process permits problem-free handling and packing of the carbon nanotube material that is produced.
摘要:
A cyclone reactor for producing a usable by-product as part of a recoverable slag layer, the reactor comprising a housing having an outer wall that defines a combustion chamber; an inlet configured to introduce a reactant into the reactor; a burner configured to combust the reactant in a flame zone near a central axis of the chamber; and an outlet configured to provide for the removal of the usable by-product from the housing; wherein the reactor is configured to combust a first portion of the reactant in an exothermic reaction in the flame zone; and wherein the reactor is configured to convert a second portion of the reactant in an endothermic reaction near the outer wall to produce the by-product as part of the slag layer.
摘要:
The invention relates to a process for esterifying free fatty acids in vegetable and animal fat with alcohols over heterogeneous acidic ion exchange resin catalysts at temperatures of 60 to 120° C.
摘要:
The present invention relates to the industrial production of vinylene carbonate (VC) by eliminating hydrogen chloride from chloroethylene glycol carbonate (CGC) or solid catalysts in the gas phase, the reaction being carried out over a catalyst bed agitated by thorough mixing.
摘要:
The present invention is based on a process for industrial scale synthesis of poly- and oligothiophenes, which works in concentrated solution. In this process, a solution which comprises an organometallic thiophene reagent is added to a second solution which comprises a catalyst.
