Shrinking the Haber-Bosch process

C&EN Global Enterprise, 2019
The Haber-Bosch process is responsible for over 1% of global carbon dioxide emissions every year, making it the biggest CO2 belcher among industrial chemical reactions.

Optimization of the Bosch CO2 Reduction Process

SAE Technical Paper Series, 1991
<div class="htmlview paragraph">Extensive development testing to support the design of the Space Station Freedom (SSF) Carbon Dioxide (CO₂) Reduction Assembly (CReA) has been conducted. Both dual and single reactor eight-person capacity systems, supported by experimental test setups, have been used to broaden the design ...

Influence of operation parameters on BOSCH-process technological characteristics

Materials Today: Proceedings, 2020
Abstract Authors investigated direct plasmachemical etching of silicon with Bosch-process using installation for inductively coupled plasma (PLATRAN-100) in gas area consist of SF6 and CHF3 gases in etching and deposition steps respectively. Defined correlations of etching rate, selectivity Si/photoresist, anisotropy, etch uniformity and sidewall ...

A modified Bosch-type process for precise surface micromachining of polysilicon

Journal of Micromechanics and Microengineering, 2002
We report on the study of a new plasma process for precise surface micromachining of polysilicon. The principle is based on the adaptation of the well-known Bosch process to polysilicon, alternating etch and passivation steps under inductively coupled plasmas (ICPs).

Optimization of Bosch etch process for through wafer interconnects

Proceedings of the 15th Biennial University/Government/ Industry Microelectronics Symposium (Cat. No.03CH37488), 2004
The Bosch etch process was utilized to create 50 micrometer vias with an aspect ration of 10:1 in silicon wafers for through wafer interconnects. The process is complex with twenty-two separate parameters required to control the process. Deviating from the standard process and flowing SF/sub 6/ during the deposition process resulted in a more stable ...

Understanding and Predicting Process Performance Variations of a Balanced Manufacturing Line at Bosch

2022
Industry 4.0 takes advantage of data-driven approaches to improve manufacturing processes. Root cause analysis (RCA) techniques are naturally required to support the identification of reasons for (in)efficiency processes. However, RCA methods tend to be sensitive to data perturbations and outliers, compromising the confidence of the results and ...

Haber-Bosch and Other Industrial Processes

2004
The Haber process, in the past more often referred to as the Haber-Bosch process, is one of the towering achievements of industrial chemistry. It has enabled us to produce enough nitrogen fertiliser to feed the current world population, to provide enough explosive to fight as many minor wars as seems desirable to desperate enough people, and to be able

Bosch: Process Mining—A Corporate Consulting Perspective

2020
As a large corporation and global player, Bosch has several Process Mining use cases implemented, in different business divisions, across different continents, and in various process types, e.g. P2P, O2C, production, and ticketing. The Bosch Process Mining setup can be characterized as a top-management-driven central approach. Planning and execution is

(Invited) Ammonia Production Beyond Haber-Bosch Process

ECS Meeting Abstracts, 2019
Ammonia has been an important chemical precursor for agriculture and other applications for about a century. It is estimated that about 180 million tons of ammonia is produced annually, and over 90% of the ammonia is produced via the Haber-Bosch (HB) process.
