Propane dehydrogenation is a process where propane is converted to propylene with the option to use the by-product hydrogen for fuel or export for other uses. A PDH unit is easily integrated at a propane source or at a downstream polypropylene production plant. Various companies are developing PDH technology to be more efficient and economical.

This document contains information on the elements of an effective Export Compliance Program (ECP) and how to build a program suitable for your company or organization. The purpose of an ECP is to create a series of procedures that help organizations operate their export activities in accordance with the Export Administration Regulations (EAR).

2025年2月24日 · PDH（Plesiochronous Digital Hierarchy），即准同步数字体系。 作为第一代 光通信 的标准，规定了一系列的速率等级和等级间的复用方法。 PDH的各速率等级称为一次群、二次群…五次群，将 数字信号 以固定的速率进行传输。 简单来说，就是PDH规定了一系列大小不同的 容器 （次群）来容纳不同数量的信号，可以满足不同业务需求。 可以把次群当做是粗细不同的水管，细的水管（低次群）流速（传输速率）较慢，粗的水管（高次群）流速（传输速率）较 …

Bis (triphenylphosphine)palladium chloride is a coordination compound of palladium containing two triphenylphosphine and two chloride ligands. It is a yellow solid that is soluble in some organic solvents. It is used for palladium-catalyzed coupling reactions, e.g. the Sonogashira–Hagihara reaction. The complex is square planar.

PDH是典型的多酶体系，将催化连续反应的几种酶结合成复杂有序的结构，以提高效率。 原核生物的复合体较为简单，大肠杆菌的PDH含有12个E1二聚体，24个E2和6个E3二聚体。 真核生物的复合体结构更加复杂，比如人的复合体除含有30个E1四聚体（α2 β 2），60个E2和12个E3二聚体外，还含有三种调控蛋白，包括E3结合蛋白（E3BP），丙酮酸脱氢酶激酶（PDK）和丙酮酸脱氢酶磷酸酶（PDP）。 原核生物的PDH直径30纳米，真核的直径50纳米，而核糖体的直径才20纳 …

2021年7月9日 · We developed a PDH catalyst that operates at thermodynamically limited conversion levels without the addition of hydrogen to the feed and exhibits excellent stability and selectivity to propylene (>99%).
