In this work, thermo-oxidative behavior, kinetic triplet, and free radical mechanism of ultraheavy oil during an in situ combustion (ISC) process were systematically surveyed via multiple thermal analysis techniques (TG/DTG/DSC/PDSC), model-free methods, related mathematical simulation. First, specific mass loss, exothermic intensity, corresponding temperature intervals respectively determined low-/high-temperature oxidation (LTO/HTO) regions. addition, the comparison atmospheric/pressurized...
Waste engine oil as industrial hazardous waste poses a great threat to the environment. It can be effectively converted into hydrogen by two-stage pyrolysis–reforming. In this work, charcoal-oil-water slurry was used for co-pyrolysis produce hydrogen-rich gas due its multi-component synergism. First, thermogravimetric analysis and kinetic calculation investigated synergistic effect of heat mass transfer in pyrolysis stage. After that, reforming experiments explored advantages reactions terms...
Chaotic pulse group (CPG) electric field has already been proposed to achieve demulsification of water-in-oil (W/O) emulsions; however, the parameters CPG for efficient emulsions are unknown. Therefore, in this study, numerical model droplet deformation under action was established by coupling flow and field, effectiveness verified comparing with experimental results. In model, optimized deformation; moreover, influence surface tension oil viscosity on optimal is discussed; droplets...
Removing particles dispersed in fluid through drops is widely presented various fields, and the critical factor captured by droplets. Drop rotation effects play a dominant role capture process. However, their influences on collection characteristics remain unclear. Thus, particle model was developed to simultaneously consider translation fine an individual droplet. The finite volume method used solve for flow field efficiency, proposed verified comparison with experimental published results....
Plastic pyrolysis is an efficient and economical method of treating plastic waste, the main products which are oil, gas coke. Oil production from waste plastics a promising technology, co-pyrolysis multicomponent material can partly promote reaction optimize products. So far, coupling mechanism between other substances remains to be further studied. Therefore, this paper examines another hazardous waste-engine oil with plastics, performance was evaluated, TG-DTG curve analyzed dynamically,...
The pyrolysis of waste plastics alleviates the ecological pollution plastics. In addition to high-quality oil component target product, there are solid residues from incomplete pyrolysis. These have a great potential as fuels due their high carbon content and partial content. Currently, few studies focused on rational utilization by-products, especially simultaneous combustion coupled mechanisms. this paper, performance plastic with different particle sizes was firstly evaluated TG-DTG...
γ-Valerolactone (GVL) is considered as a versatile platform chemical obtained from biomass refinery. In this study, eco-friendly group III metal (Sc, Y, La) triflates were examined homogeneous catalysts for microwave-assisted transfer hydrogenation of ethyl levulinate (EL) to GVL under mild conditions. Experimental results revealed that the selectivity has positive relationship with Lewis acidity ion, which related effective charge density center (3.23, 2.81, 2.60 Sc3+, Y3+, La3+,...
