Future of bioethanol…

Bioethanol.

Alternatives to petroleum-derived fuels are being sought in order to reduce the world's dependence on non-renewable resources. The most common renewable fuel today is ethanol derived from corn grain (starch) and sugar cane (sucrose). It is expected that there will be limits to the supply of these raw materials in the near future, therefore lignocellulosic biomass is seen as an attractive feedst...

Capacity Development Programming of Bioethanol Fuel Refineries in Iran

The purpose of this paper is design a model for the capacity development of bioethanol refineries in Iran. Due to the variable weather condition, there is the uncertainty in the amount of raw materials, thus we suggest a deterministic programming model Based on probabilities for capacity development. The deterministic linear programming model is represented a signal period planning framework to...

Catalytic Hydrogen Production from Bioethanol

Flexibility in wheat bioethanol plants

Bioethanol is mostly produced from wheat starch in Sweden. Due to the increasing wheat price it is no longer profitable to produce bioethanol from wheat. In this paper the conditions for converting a wheat bioethanol plant to a lignocellulosic bioethanol plant are studied. The most suitable lignocellulosic feedstock is investigated and soft wood chips are chosen based on bioethanol ...

Process engineering economics of bioethanol production.

This work presents a review of studies on the process economics of ethanol production from lignocellulosic materials published since 1996. Our objective was to identify the most costly process steps and the impact of various parameters on the final production cost, e.g. plant capacity, raw material cost, and overall product yield, as well as process configuration. The variation in estimated eth...
