Platinum nanocatalysts supported on Vulcan XC-72 carbon have been synthesized through the reduction of chloroplatinic acid with formic acid, using surfactant tetraoctylammonium bromide (TOAB) as stabilizer in solvent tetrahydrofuran (THF). These are by changing molar ratio TOAB to i.e., N/Pt 0.76, 0.38, and 0.19. A control catalyst that does not contain is also this method for comparison purposes. Comparison morphological properties these catalysts transmission electron microscopy (TEM)...

This paper presents a solution algorithm and effective mathematical formulations for short-term scheduling of crude oil unloading, storage, processing with multiple types, berths, units. The problem can be formulated as mixed-integer nonlinear programming (MINLP) model. However, solving MINLP model directly results in inconsistency quality time. proposes that iteratively solves two linear (MIP) models (NLP) model, resulting better quality, stability, efficiency than the directly. proposed...

Abstract Energy optimization is a hot research topic for design and operation of crude oil distillation plants. Optimum energy utilization in multistage process achieved by optimizing the load each column as well yield sidestreams columns. A generalized consumption model proposed, optimal distribution accomplished minimizing total consumption. Based on loads, nonlinear programming then formulated to determine yields maximizing thermal exergy recovery plant. Finally, four‐stage plant...

Well-dispersed Pt nanoparticles of an average size 2.2 nm were produced on multiwalled carbon nanotubes (MWNTs) pretreated by concentrated sulfuric and nitric acids to improve the catalyst adsorption. Reduction chloroplatinic acid was done methanol. A zwitterionic surfactant 3-(N,N-dimethyldodecylammonio)propanesulfonate used stabilize nanocatalyst. This method is simple reproducible. The resultant exhibits a slightly higher performance for oxygen reduction reaction than corresponding Pt/C....

Some independent plants making up a chemical or petrochemical site are linked by process streams. Linking streams are, in general, cooled up-plants and reheated down-plants to satisfy requirements. These streams, even more, travel from storage tanks and, then, down-plants, which results low energy-use efficiency. Up-plants with multiple hot discharges feeds proposed this paper, T–Q graphic method is presented target the temperature of discharges/feeds between plants. The diagram composed...
