A review on the production of glycol from glycerol

by mpob_admin

Crude glycerol is the primary by-product of the biodiesel industry and too costly to purify it into a higher quality product. However, glycerol can be converted into other useful products used in the pharmaceutical and cosmetics industries such as trimethylene glycol (1,3-propanediol), propylene glycol (1,2-propanediol), ethylene glycol and ethanol through the hydrogenation process and the microbial fermentation process. This article reviews factors affecting glycerol conversion, glycol selectivity, concentration and conversion yield through both the hydrogenation and microbial fermentation processes.

 
Gliserol mentah merupakan hasil sampingan utama industri biodiesel yang terlalu mahal untuk ditukar menjadi produk yang bermutu tinggi. Gliserol boleh ditukarkan kepada beberapa produk berguna untuk industri farmaseutikal dan kosmetik seperti trimetilena glikol (1,3-propanediol), propilena glikol (1,2-propanediol), etilena glikol dan etanol melalui proses penghidrogenan dan proses fermentasi mikroorganisma. Artikel ini melaporkan faktor yang mempengaruhi penukaran gliserol, pemilihan kepekatan dan penghasilan glikol melalui proses penghidrogenan dan fermentasi mikroorganisma.

Material flow cost accounting (MFCA): a brief introduction

Since the advent of the Industrial Revolution in the early 19th century, man has started to pollute the environment. This was accelerated after the Second World War when synthetic materials began to appear. The production of these materials and other new inventions that greatly impact on the socio-economic conditions of the populace also greatly accelerated […]
