Fischer-Tropsch synthesis catalyst evaluation apparatus principle synthesis gas as a raw material, synthetic process with paraffin-based liquid fuels in the catalyst and appropriate reaction conditions. Coal and natural gas is converted to liquid fuel core technology. Process equipment design gas pretreatment unit, reaction unit and the acquisition unit. Feed gas preheated by a certain percentage mixed into the fixed bed reactor, the feed gas mass flow controller with metering, the use of three-stage reactor was electrically heated furnace, the reaction product from the reaction out of the first gas-liquid separation unit, liquid material into the liquid storage tank, exhaust filter is emptied or access on-line analyzers. Technical parameters reaction pressure: 0.1 ~ 10.0MPa control accuracy ± 1% FS reaction temperature: room temperature ~ 600 ℃ control accuracy ± 1 ℃ catalyst loading volume: 20ml gas flow: 0 ~ 200ml / min control accuracy of ± 1% FS functional characteristics - Instrumentation , pumps, valves using domestic brand-name products, to ensure system reliability and stability; - computer dual-mode automatic control and manual control combined with easy operation; - the establishment of the reaction conditions and low limit alarm interlock to ensure the safety device operation; - the components are modular design, versatility, ease of installation and maintenance; - to achieve the temperature, pressure, flow, level and other automatic control; - automatic data acquisition, storage, printing;
