“…Important works have been carried out in the last period to upgrade heavy cuts, like atmospheric or vacuum residues, into valuable distillates using catalysts (Shimada et al, 2009;Elizalde et al, 2009;Rana et al, 2007;Ancheyta et al, 2005;Zhang et al, 2005;Kressmann et al, 1998;Morel et al, 1997;Toulhoat et al, 1990). This conversion requires demetallation (Ni and V), sulfur and nitrogen subtraction.…”

Processing of Heavy Crude Oils - Challenges and Opportunities

View full text Add to dashboard Cite

With the increasing demand of petroleum-derived products due to the world population and development, upgrading of crude oil with heavier quality and petroleum residues is unavoidable. Hydroprocessing is a preferable process for heavy oil upgrading. The process is operated with the presence of a catalyst, and catalysis plays an important role in the process. An overview regarding the catalyst design such as the catalyst active metal, active phase, support properties, and catalyst structure for heavy oil hydroprocessing is provided. There also include some recent advancements related to catalytic hydroprocessing of heavy oils and residue processes. Further catalyst performance improvement will likely come from catalyst optimization and better catalyst deactivation resistance resulting from metal poisoning and coke formation.

“…Este último consiste em reatores trifásicos (gás-líquido-sólido) onde há presença de óleo a ser processado, hidrogênio pressurizado e partículas sólidas catalíticas. Destacam-se, então, para este estudo as colunas de bolha operando em leito de lama, que possuem a fase sólida agindo como meio catalítico do processo (MOREL et al, 1997 Neste trabalho faz-se o uso combinado das técnicas numérica (CFD) e experimental (Stereo-PIV) com o objetivo de avaliar a influência da fase sólida em uma coluna de bolhas com geometria diferenciada.…”

RESUMOEscoamentos multifásicos são amplamente utilizados em diversos setores industriais. Os resíduos pesados de petróleo podem ser hidrocraqueados em reatores trifásicos (gás-líquido-sólido) e a influência da fase sólida no escoamento é de grande importância nesse tipo de processo. O estudo da fluidodinâmica no interior dos equipamentos permite melhorias de projeto e, por consequência, maior eficiência na quebra dos resíduos. Neste trabalho são utilizadas duas técnicas de análise combinadas para avaliar e predizer o comportamento fluidodinâmico no interior de uma coluna de bolhas com expansão de diâmetro em casos bifásicos e trifásicos. São elas: Velocimetria por Imagem de Partícula (PIV) e Fluidodinâmica Computacional (CFD). Experimentalmente, na análise por PIV, foram avaliadas 5 vazões diferentes da fase gasosa com e sem a presença de material particulado e as duas vazões mais elevadas são comparadas com dados numéricos (CFD). Os resultados numéricos e experimentais apresentaram concordância e a presença de sólidos produziu mudanças nos campos e perfis de velocidade em todos os casos.
