據(jù)美國鉆井網(wǎng)站2023年7月27日報道，由雪佛龍公司和格雷斯公司合資成立的先進精煉技術(shù)公司(ART)日前推出了一種加氫處理催化劑解決方案——ENDEAVOR?，這種解決方案可以100%利用植物油、成品油、動物脂肪和潤滑脂等可再生資源生產(chǎn)可再生柴油(RD)和可持續(xù)航空燃料(SAF)。

ART在周二的新聞發(fā)布會上表示：“這個聲明是在可再生運輸燃料需求大幅增長的背景下發(fā)布的。”

ART總經(jīng)理Nathan Ergonul表示：“ENDEAVOR?催化劑是一項廣泛研發(fā)計劃的成果，已經(jīng)在多個煉油廠應(yīng)用中展示了一流的性能。ART將繼續(xù)投資于這一令人興奮的領(lǐng)域，以我們在污染物去除和脫蠟方面的技術(shù)領(lǐng)先地位為基礎(chǔ)，使客戶能夠最大限度地提高各種生物飼料的產(chǎn)量和利潤。我們與領(lǐng)先的工藝許可商雪佛龍Lummus Global (CLG)合作，使我們能夠充分優(yōu)化可再生能源工藝。” 

ART說：“催化劑在可再生原料加氫加工中起著至關(guān)重要的作用。用于污染物捕獲、脫氧和異構(gòu)化的催化劑是處理更廣泛的生物飼料以提高產(chǎn)品產(chǎn)量和確保滿足產(chǎn)品規(guī)格的關(guān)鍵。”

ENDEAVOR?催化劑體系由EnRich保護和加氫處理催化劑組成，包括雪佛龍的EnHance?異構(gòu)化催化劑，這些催化劑都是專門為處理可再生原料而開發(fā)的。

RD和SAF等可再生燃料有望在重型運輸?shù)拿撎贾邪l(fā)揮關(guān)鍵作用。ART表示，根據(jù)美國能源部(DOE)的數(shù)據(jù)，與基于化石燃料的同行相比，RD和SAF的最終用戶顯著減少了溫室氣體排放。

美國能源部今年早些時候表示，到2025年底前，目前的可再生柴油產(chǎn)能可能會增加一倍以上。據(jù)估計，到去年年底，美國可再生柴油的日生產(chǎn)能力達到17萬桶，或每年26億加侖。盡管美國能源部預(yù)計一些已宣布的項目將被推遲或取消，但如果所有項目按計劃開始運營，到2025年底前，美國可再生柴油的日產(chǎn)能將達到38.4萬桶，即59億加侖年產(chǎn)能。

Chevron Launches Solution to Make Renewables-based Diesel, Aircraft Fuel

A joint venture by Chevron and W.R. Grace & Co., Advanced Refining Technologies (ART), launched ENDEAVOR?, a hydroprocessing catalyst solution to produce renewable diesel (RD) and sustainable aviation fuel (SAF) from 100 percent renewable sources, such as vegetable oils, refined oils, animal fats, and greases.

“The announcement comes against the backdrop of significant demand growth for renewable transportation fuels”, ART said in a press release Tuesday.

"ENDEAVOR? catalysts are the culmination of an extensive R&D program and have already demonstrated top-tier performance in several refinery applications,” said ART’s Managing Director Nathan Ergonul. “ART will continue to invest in this exciting segment, building on our technology leadership in contaminant removal and dewaxing to enable customers to maximize yields and profits from a wider variety of biofeeds. Our collaboration with Chevron Lummus Global (CLG), a leading process licensor, allows us to fully optimize the renewables process."

“Catalysts play a critical role in the hydroprocessing of renewable feedstocks. Catalysts for contaminant capture, deoxygenation and isomerization are key for processing a wider range of biofeeds to increase product yields and to ensure product specifications are met”, ART said.

The ENDEAVOR? catalyst system consists of EnRich guard and hydrotreating catalysts and includes Chevron's EnHance? isomerization catalysts, all developed specifically for processing renewable feeds.

Renewable fuels such as RD and SAF are expected to play a key role in the decarbonization of heavy-duty transportation. According to the U.S. Department of Energy (DOE), end-users of RD and SAF significantly reduce their greenhouse gas emissions compared to their fossil fuel-based counterparts, the company said.

The DOE said earlier this year that current renewable diesel production capacity could more than double by the end of 2025. It estimates USA renewable diesel production capacity was 170,000 barrels per day (b/d), or 2.6 billion gallons per year (gal/y), at the end of 2022. Although the DOE expects some announced projects to be delayed or canceled, if all projects begin operations as scheduled, USA renewable diesel production capacity could reach 384,000 b/d, or 5.9 billion gal/y, by the end of 2025.
