Chiyoda CT‐HBT

Novel Hybrid Titania Catalyst for Hydrodesulfurization in ULSD Production

On September 26, 2018, Anne Wong and Robert Schneider, both of Chiyoda’s Houston office, co-presented a paper on new technology developments at the Houston IRPC America’s Conference.

Chiyoda has developed and commercialized a highly activated hydrodesulfurization (HDS) catalyst, CT‐HBT, which can convert feedstocks containing highly concentrated hard‐to‐desulfurize middle distillate into high‐value‐added diesel oil with a sulfur content of 10‐15 ppm or less.  The key to this new development is the adoption of titania‐coated alumina as a support.

CT‐HBT has demonstrated itself to be a superior catalyst with an HDS activity 1.5 times that of a conventional alumina catalyst. Adopting a catalyst with high HDS activity allows refineries to improve profitability by converting light cycle oil (LCO), a hard‐to‐desulfurize middle distillate produced by fluid catalytic cracking (FCC), into more valuable diesel oil. For easy‐to‐desulfurize feedstocks, the catalyst life is extended which halves the frequency of catalyst replacement in certain conditions, boosting potential profits even further.

In 2014, Chiyoda demonstrated the catalyst’s high performance when processing a feedstock with high LCO content in the first commercial application of CT‐HBT in an HDS unit for kerosene and diesel oil at the Seibu Oil Company Limited in Japan. The unit was operated successfully for three consecutive years on an annual cycle of eight months for the production of diesel oil and four months for kerosene. During the diesel oil production period, a feedstock containing LCO up to a content of 30% was stably processed for two years. Based on these results, CT‐HBTwasadoptedin2016and2017atthreerefineriesinJapan. Seibu Oil has decided to replace their existing HDS catalyst for ULSD production with a second charge of CT-HBT.

Chiyoda Young Innovators’ Academy

The goal of the two-week Chiyoda Young Innovators’ Academy is to interest students entering 7th, 8th and 9th grade in topics of engineering, programming and inventions in an effort to cultivate their STEM skills.

Students will experience hands-on activities; design, build, and innovate ideas for inventions; and participate in the Summer Young Inventors’ Showcase hosted by the Inventors Association of America-Houston Chapter.


2018 Academy

University Of Houston Newsletter

During the Academy, students participated in an array of design challenges, building parachutes and bottle rockets and reverse engineering common objects, like coffee mugs. They also got involved in programming to create and develop games and learned to use microcontrollers that allowed them to make a robotic finger move.



Chiyoda International Corporation participated in “Fill a Backpack” drive to provide children in need with school supplies for the upcoming year. Our goal was to fill 20 backpacks, but our great employees exceeded expectations and filled 24 backpacks, volunteering time and monetary support to accomplish the task. The backpacks were donated to HISD Sylvan Rodriguez Elementary, home of the Space Rangers.


Sylvan Rodriguez was one of the first Texas Title 1 elementary schools to adopt the International Baccalaureate Primary Years Program. The school population is designated as being 98% economically disadvantaged, yet they report a 97% attendance rate and a 98.3% promotion rate. This year, the need for supplies was even greater due in part to Hurricane Harvey and to budget cuts in the school district. The school leaders, staff, and parents work together to help these children succeed in spite of the challenges and it was Chiyoda’s honor to support them.
