Operation Conditions Analysis of Higher Alcohol Synthesis via Syngas from High Temperature Gasification of Black Liquor
摘要
Abstract
The objective of the paper is to optimize the operation conditions of higher alcohol synthesis via raw syngas from high temperature gasification of black liquor. The process of CO2 removal from syngas is simulated by commercial software Aspen plus. The variations of H2S content, absorbent consumption and heat load for absorbent regeneration with CO2 content in clean singes (reactant) are analyzed. The synthesis process is analyzed based on the model of a fixed bed reactor and K/MoS2 catalyst. Products distributions and yields are predicted. The influence of operation conditions, including CO2 content in reactant, catalyst loading, reaction temperature and pressure on CO conversion ratio, selectivities of alcohol, hydrocarbon, CO2 and ester, mass content of C2 + alcohol and space time yield are studied by sensitive studies. Analysis results show that the optimum operation conditions of the reactor are: temperature 310~330℃ , pressure 9~11 MPa, catalyst loading ratio 20 ~30 g·h/mol and CO2 content 1. 6% .关键词
