Abstract
The oxidation–extraction desulfurization of Saudi Arabian crudes was conducted with hydrogen
peroxide–acetic acid oxidation system. The selection of extractant, the
optimization of oxidation–extraction conditions, and the exploration of
desulfurization mechanism were studied. As DMF was used as the extractant, the
optimal desulfurization rate of 35.11 % and oil recovery of 95 % were obtained
at 70 °C with the molar ratio of peracetic acid to sulfur of 8:1, the molar
ratio of acetic acid to hydrogen peroxide of 2:1 and the volume ratio of
extractant to oil of 1:1. The desulfurization effect of different fractions in
the treated Saudi Arabian crudes was found to obey the following order:
gasoline–diesel fraction >VGO fraction >VR fraction, due to different
types and structures of sulfur compounds. The oil quality was less affected and
most sulfides were mainly extracted via DMF.

Anyone with a research interest in desulfurization and a curiosity as to how
Saudi Aramco is approaching this problem should consider attending this forum.
Presentations from the 4th Forum included …

KACST-King Abdulaziz City of Science and Technology- commissioned Thomson
Reuters to produce a report titled Strategic Review of the Petrochemicals and Oil Processing
Technology Landscape. The
report, which is available for free download at http://www.kacst.edu.sa/en/about/publications/Other%20Publications/STRATEGIC%20REVIEW%20OF%20THE%20PETROCHEMICALS%20AND%20OIL%20PROCESSING%20TECHNOLOGY%20LANDSCAPE.pdf
has so much to offer I hardly know where to begin. So, I will begin with the obvious. Its primary purpose is to help Saudi Arabia
position itself strategically within this global industry.
Using bibliometrics (http://en.wikipedia.org/wiki/Bibliometrics),
the authors of the report determine which entities produce the most peer
reviewed papers in each of 40 technology categories. They do the same for patents.
Table 20 of the report lists the top five entities in each technology in the
peer reviewed paper realm. Interestingly, the Chinese Academy of Sciences (http://english.cas.cn/) is the top producer
in 28 of the 40 technologies.
Table 37 lists the top five assignees of patents in each category. The top two entities in all categories
combined are China Petrochemical Co Ltd. and China Petro-Chem Corp., followed by
UOP in the U.S., and Japan's Sumitomo Chemicals.
For a bibliographic researcher, this is gold.
I can use these lists to focus my search on the organizations most
likely to produce results in any given category.
Table 5 lists the total papers produced from 1995-2011 in each of the 40
categories. The top two are …
Petrochemicals
Synthesis - Processes – Polymerization
Petrochemicals Synthesis - Processes - Oxidation
The keywords suggested by Table 5 are extremely useful in focusing my research
in such a way as to produce fruitful results.
In this post I have just scratched the surface in tips on how to mine this
resource. Take a look at it, and let me
know what you think.

KACST-Oxford Petrochemical Research Centre
KACST and the University of Oxford have created a joint research centre called
KACST – Oxford
Petrochemical Research Centre (KOPRC).
This joint scientific cooperation between KACST and University of Oxford
is the first of its type in the Arab world in the refining and petrochemical
fields and comes within the strategic plan set by KACST with the aim of
transferring and localizing petrochemicals technology in the Kingdom.
The work of the centre is focused on the following areas:
Developing a solid acid catalyst for
alkylation processes
Developing a process to convert the
fossil remains of distillation to olefins
Developing catalysts to convert carbon
dioxide to chemicals
Simulating the development of materials
for selective polymerization processes
Simulating the development of materials
for the process of burning clean fuel

Abstract
Zeolite materials have proved very useful as chemical catalysts and the search
for new zeolite structures with novel channel and pore shapes is ongoing. We
discuss a geometric feature of zeolite frameworks, the flexibility window,
which may provide a criterion to identify hypothetical structures which can be
synthesised as zeolites. In recent research using data on zeolite frameworks
under compression, we show strong links between this geometric feature and the
physics of zeolite frameworks.
