Abstract

Branched-preformed particle gel (B-PPG) is a novel agent for EOR application in mature reservoirs. To improve the enhanced oil recovery (EOR) performance of B-PPG, the heterogeneous combination flooding system composed of B-PPG, hydrolyzed polyacrylamide (HPAM), and surfactant was proposed. However, the synergistic mechanism of B-PPG and HPAM still remains unclear. Here, a series of experiments were performed to study the viscosities of HPAM, B-PPG, and mixture of HPAM and B-PPG, evaluate the suspension stability of B-PPG and mixture of HPAM and B-PPG, to investigate the propagation behavior of HPAM, B-PPG, and a mixture of HPAM and B-PPG through porous media, and to study the EOR performance of HPAM, B-PPG, and a mixture of HPAM and B-PPG in heterogeneous reservoirs by performing parallel sand pack flooding experiments. Results show that the suspension stability of B-PPG can be improved by adding polymer due to the increase in viscosity. The higher the HPAM concentration is, the higher viscosity of mixtu...

Abstract

Pyrolysis of dried sewage sludge is regarded as an effective treatment method as well as a promising technology for energy/fuel production. In this work, thermochemical conversion of dried sewage sludge in a continuous reactor at different pyrolysis temperatures (400–800 °C) and solid residence times (6–46 min) was conducted. The pyrolysis products obtained using different pyrolysis conditions were extensively investigated. It is indicated that high pyrolysis temperature (>700 °C) and long solid residence time (>23 min) could enhance secondary reactions and decrease the yield of bio-oil. The maximum yield of bio-oil of 16.69% was achieved at reaction temperature of 700 °C and solid residence time of 23 min. The FTIR and GC-MS analyses of the bio-oil obtained at optimum condition indicated that it contained large amounts of phenols and esters. H2 and CO2 were the main components of pyrolysis gas, with a total amount that exceeded 52.18%. The characteristics of the char, including elemental composition, fun...
