Catalytic pyrolysis is a promising thermochemical conversion route for lignocellulosic biomass that produces chemicals and fuels compatible with current, petrochemical infrastructure. Catalytic modifications to pyrolysis bio-oils are geared towards the elimination and substitution of oxygen and oxygen-containing functionalities in addition to increasing the hydrogen to carbon ratio of the final...
Diesel fuels of 50 and 15 ppm of sulfur content were produced in a pilot plant by upgrading light catalytic cracking gas oil (LCO) during 10 weeks of continuous operation. The end-of-run catalysts were characterized before and after soluble coke extraction by CH2Cl2. The cokes were characterized by CNMR, TPO, GC-MS, and elemental analysis. Catalyst surfaces were characterized by XPS, CO adsorpt...
Ñ Anticoking Coatings for High Temperature Petrochemical Reactors Ñ Coke deposition is a major problem for several refinery and petrochemical processes, among which steam cracking for ethylene production. Decreasing coking rates will reduce decoking frequency and will also decrease heat transfer degradation. For these processes, a means of reducing coking phenomena is the application of anticok...
Oil testing has found widespread use in assessing the quality of the insulation system of a transformer. Techniques such as Dissolved Gas Analysis (DGA) have been proven to be reliable in this task, but are expensive, laborious and time consuming. It is also not available for field use. This paper proposes the combined use of gas and optical sensing technology for the testing of transformer oil...
Fluid catalytic cracking (FCC) is a method of vegetable oils into simpler fractions and green fuel oils. One component the FCC system furnace. The furnace where combustion process occurs provides high heat transfer throughout system, especially for heating reactor. reactor temperature catalyst temperature. depends on feed oil used in process, such as crude palm at 450‒550 °C or bio-oil 300 °C. ...
Biodiesel production through transesterification or catalytic hydrogenation using vegetable oil is a sustainable method, but it has the downsides of by-product generation and higher cost. Therefore, in this study, waste cooking was selected as raw material, fluidized cracking carried out on catalyst (LDO-75) fixed-fluidized-bed (FFB) reactor. The effects reaction temperature, catalyst–oil ratio...
whereas American industry has available large supplies of natural gas; the refiner in the U.S.A. can therefore produce high quality fuels partly by catalytic cracking of heavy distillates, but his European counterpart has no such opportunity and must rely to a much greater extent on catalytic reforming processes to produce high quality fuels from straightrun naphthas. Again, while demand for hi...
At present no company develops oil and gas fields without constructing geologic and hydrodynamic models. This is due in particular to the fact that recently the emphasis in design, planning and monitoring has shifted to overdissected and low-permeability reservoirs. To assess economic efficiency and optimal placement of wells and to predict hydrocarbon production levels, it is important to have...
